Code Cleanup

Apply file layout

Reorders type members in files according to the rules configurable on the Code Editing | C# | File Layout page of ReSharper options. For more information, see File and Type Layout.

Code Styles

Use explicit or implicit modifier definitions for type members

Applies the rule for type member modifiers - whether on not to use the private modifier explicitly. The rule is configurable on the Code Editing | C# | Code Style page of ReSharper options. For more information, see Code Syntax Style: Modifiers.

Apply arguments style (named | positional)

Applies the preferences for named/positional arguments for specific types of parameters. The preferences are configurable on the Code Editing | C# | Code Style page of ReSharper options. For more information, see Code Syntax Style: Named/Positional Arguments.

Add parentheses to explicitly specify operation precedence

Adds optional parentheses to clarify precedence of operations in cases specified on the Code Editing | C# | Code Style page of ReSharper options. For more information, see Code Syntax Style: Optional Parentheses.

Arrange attributes

Applies the rules for multiple attributes as specified on the Code Editing | C# | Code Style page of ReSharper options. For more information, see Code Syntax Style: Multiple Attributes.

Remove code redundancies

• 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.

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.

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.

Optimize 'using' directives

• 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.

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.

ASP.NET

HTML

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.

Terminates statements

Terminates JavaScript statements with the semicolon.

Correct 'var' to 'let'/'const' where possible

• In JavaScript code, if the target JavaScript language level is ECMAScript 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.

Convert string concatenations to template strings

In JavaScript code, if the target JavaScript language level is ECMAScript 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:

Reformat embedded XML doc comments

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

Remove redundant qualifiers

Use this option to remove redundant type name qualifiers.

Optimize reference comments

Use this option to remove redundant reference comments.

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.

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.

XAML

XML

C++

Apply Clang-tidy fix-its

In this node, you can choose all or specific fixes that will be applied according to the Clang-Tidy checks.

The selected fixes will be applied even if the corresponding inspections are turned off on the Code Inspection | Inspection Severity page of ReSharper options. Please be careful when enabling too many checks at once — code cleanup runs Clang-Tidy only once for a given file, so if multiple fixes touch the same block of code, the changes might conflict with each other.

Update file header

Inserts or updates the file header comment that you can configure on the Code Editing | File Header Text page of ReSharper options. For more information, see File Header Style.

Remove code redundancies

Removes redundant code the same way as for C# Language

Shorten qualified references

Replaces fully qualified names with short names when possible by importing namespaces, implementing settings configured on the Code Editing | VB.NET | Inspections page of ReSharper options.

Reformat embedded XML doc comments

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

Alphabetize properties

Rearranges CSS properties in the alphabetical order.
