Code Cleanup

ReSharper | Options | Code Editing | Code Cleanup

This page of ReSharper options allows you to manage and configure custom cleanup profiles, as well as to assign a cleanup profile for the silent code cleanup. The two default profiles (Full Cleanup and Reformat Code) are also shown here. You cannot modify modify them, but you can clone them to make new custom profiles.

Toolbar controls

Use the following controls to configure the selected cleanup profile:

ItemDescription
/help/img/dotnet/2017.2/ThemedIcon.CodeCleanupOptionPage.Screen.[Gray].png Set as default Click this button to use the selected profile for silent cleanup. The profile used for silent cleanup is marked with the /help/img/dotnet/2017.2/ThemedIcon.CodeCleanupOptionPage.Screen.[Gray].png icon.
/help/img/dotnet/2017.2/ThemedIcon.Duplicate.Screen.[Gray].png Duplicate Click this button to create a copy of the selected profile. If you have default settings, you will need to duplicate one of the default cleanup profiles to create a custom cleanup profile. As soon as a new profile is created, it opens in the editing mode, where you can configure the list of cleanup tasks.
/help/img/dotnet/2017.2/ThemedIcon.Behaivior.Screen.[Gray].png Configure Click this button to enable the editing mode for the selected custom profile. Note that default profiles (Full Cleanup and Reformat Code) cannot be edited.
/help/img/dotnet/2017.2/ThemedIcon.Edit.Screen.[Gray].png Rename Click this button to rename the selected custom profile. Note that default profiles (Full Cleanup and Reformat Code) cannot be renamed.
/help/img/dotnet/2017.2/ThemedIcon.Remove.Screen.[Gray].png Remove Click this button to remove the selected custom profile. Note that default profiles (Full Cleanup and Reformat Code) cannot be removed.
/help/img/dotnet/2017.2/ThemedIcon.Success.Screen.[Gray].png Done Click this button exit the editing mode and go back to the preview of the selected profile. Note that your modifications will not be applied unless you click Save.

Code cleanup tasks for selected profile

These tasks become configurable when you switch the editing mode (/help/img/dotnet/2017.2/ThemedIcon.Behaivior.Screen.[Gray].png Configure) for the selected custom cleanup profile. Initially, there are no custom profiles and tasks of the default profiles cannot be edited. You can click /help/img/dotnet/2017.2/ThemedIcon.Duplicate.Screen.[Gray].png Duplicate to create an editable copy of one of the default profiles and then edit its tasks.

Enforce 'var' keyword usage settings Applies the rules for 'var' usage during the cleanup. The rules are configurable on the Code Editing | C# | Code Style page of ReSharper options .
Remove code redundancies On the Code Inspection | Inspection Severity page of ReSharper options , in the Redundancies in Code categories for most languages, ReSharper lists over 50 redundancies that have associated code inspections. Some of them require special attention, and you simply cannot process them in the batch mode. That leaves Code Cleanup with about 30 redundancies that it is able to remove automatically whenever you select Remove code redundancies in your cleanup profile.
Specifically, code cleanup:
  • Removes:
    • Redundant empty constructors.
    • Explicit integer type specifiers in enumerations.
    • true specifiers in for statements.
    • Redundant type casts.
    • Redundant parentheses from attributes without arguments.
    • Explicit calls to base class constructors without arguments.
    • Redundant boolean comparisons.
    • Redundant braces from collection initializers with a single expression.
    • Redundant explicit delegate creation expressions.
    • Empty argument lists from object/collection initializers.
    • Redundant new keywords.
    • Redundant partial modifiers on type declarations where a type has a single part.
    • Redundant unsafe contexts and statements.
    • Redundant object.ToString() calls (for example, in a concatenation with a string or as an argument of a string.Format() call).
    • Redundant string.ToCharArray() calls.
    • Redundant specifications of argument types.
    • Signatures in anonymous methods where its parameters are not used in the method body.
    • Non-referenced labels.
    • Redundant field initializers.
    • Redundant explicit names in anonymous type properties.
    • Redundant nullable types where value type is implicitly convertible to nullable.
  • Converts:
    • Nullable types to short form Nullable<T> to T?).
    • Static method invocations to extension method calls where extension methods are invoked as static methods.
    • To implicitly typed array creation expressions when array type can be inferred from initializer.
  • Fixes:
    • Occurrences where static members of a type are accessed via derived members of the type.
Use auto-property, if possible Replaces simple properties and corresponding backing fields with auto-properties. For more information, see Using Auto-Properties.
Make field read-only, if possible Adds the 'readonly' keyword to fields that are assigned in the declaration or in a constructor and only have read usages. For more information, see Making Fields Readonly.
Make auto-property get-only, if possible Removes the redundant set accessor on auto-properties that are initialized from the constructor/initializer and have no write usages. Note that this task only works for C# 6.0. By default, ReSharper automatically detects C# version based on the associated compiler. However, you can specify the target C# version explicitly by selecting the project in the Solution Explorer and using the C# Language Level property in the Visual Studio's Properties window (choose View | Properties Window in the menu) .
Arrange qualifiers Applies the rules for qualifying type members. The rules are configurable on the Code Editing | C# | Code Style page of ReSharper options . For more information, see Code Syntax Style: Optional Member Qualifiers.
Fix built-in type references Applies the rule for built-in type names (C# keyword or CLR type name). The rule is configurable on the Code Editing | C# | Code Style page of ReSharper options . For more information, see Code Syntax Style: Built-In Type References.
Optimize 'using' directives Provides the following configurable options:
  • Optimize 'using' directives
    Removes unused namespace import directives by implementing the rules that you can configure on the Code Editing | C# | Namespace Imports and Code Editing | C# | Code Style options pages and sorts the namespace import directives: all System.* namespaces go first, sorted alphabetically by the second word after the dot; all other namespaces go next, in alphabetical order. . For more information, see Code Syntax Style: Namespace Imports.
  • Embrace 'using' directives in region
    If this check box is selected, a new region for wrapping all namespace import directives is created during cleanup.
  • Region name
    Allows specifying a name for the region wrapping namespace import directives.
Shorten qualified references Replaces fully qualified names with short names when possible by importing namespaces, implementing settings configured on the Code Editing | C# | Code Style page of ReSharper options .
Reformat code Reformats your code according to the preferences that you can configure on the Code Editing | C# | Code Style page of ReSharper options . For more information, see Managing and Applying Code Formatting Rules.
Reformat embedded XML doc comments Reformats XML doc comments according to options configurable on the Code Editing | XML Doc Comments | Formatting Style page of ReSharper options .

Note that ReSharper does not reformat plain comments like:
// A plain single-line comment
or
/* A plain multi-line comment */

ASP.NET
Optimize @Register directives Removes unused @Register directives.
HTML
Reformat code Reformats your code according to the preferences that you can configure on the Code Editing | HTML | Code Style page of ReSharper options . For more information, see Managing and Applying Code Formatting Rules.
Normalize quotes around attribute value Applies the preferred quote style: single quote (') or double quote (") , configurable on the Code Editing | HTML | Code Style page of ReSharper options .
JavaScript/TypeScript
Terminates statements Terminates JavaScript statements with the semicolon.
Normalize quotes around string literal Applies the preferred quote style: single quote (') or double quote ("). The preference can be configured on the Code Editing | TypeScript | Code Style page of ReSharper options . For more information, see Code Style Assistance in JavaScript.
Correct 'var' to 'let'/'const' where possible let and const are supported in the following cases:
  • In JavaScript code, if the target JavaScript language level is ECMAScropt 6 (you can choose it on the Code Editing | JavaScript | Inspections page of ReSharper options )
  • In TypeScript 1.4, if the target ECMAScript 6 is selected in the project properties.
  • In TypeScript 1.5 or above.
Move block-scope variables to most possible inner scopes Moves variables defined outside of a function/compound statement, etc. closer to their usages if there are no other usages in outer scopes.
Convert string concatenations to template strings In JavaScript code, if the target JavaScript language level is ECMAScropt 6 (you can choose it on the Code Editing | JavaScript | Inspections page of ReSharper options ) , as well as in TypeScript 1.4 or above, this option will convert string concatenations to template strings. For example:
var str1 = "Hello,"; var str2 = "Test: " + str1 + " World1";
will be converted to
const str1 = "Hello, "; const str2 = `Test: ${str1} World1`;
Reformat code Reformats your code according to the preferences that you can configure on the Code Editing | JavaScript | Code Style page of ReSharper options . For more information, see Managing and Applying Code Formatting Rules.

// A plain single-line comment
or
/* A plain multi-line comment */

TypeScript specific
Remove redundant qualifiers Use this option to remove redundant type name qualifiers.
Optimize 'import' statements Use this option to remove redundant 'import' statements or fully-qualified names according to the settings configurable on the Code Editing | TypeScript | Inspections page of ReSharper options .

Add explicit 'any' type annotation if needed This options lets you add explicit 'any' annotation to types according to settings configurable on the Code Editing | TypeScript | Inspections page of ReSharper options .
Synchronize type annotation presence with code style This options lets you enforce explicit/implicit typing according to settings configurable on the Code Editing | TypeScript | Inspections page of ReSharper options .
Fix relative path style in 'require' if needed Applies the Relative file reference style in 'require' code style preference for relative paths in the require keyword. For example, import X = require("file1") or import X = require("./file1"). You can configure this preference on the Code Editing | TypeScript | Inspections page of ReSharper options .
Use 'as' instead of type assertions Replaces
var bar = <string> foo;
with
var bar = foo as string;
which is a recommended way to avoid ambiguity with JSX syntax.
