3.1

Code Completion

ReSharper complements and extends Visual Studio's native code completion of C# and VB.NET code (IntelliSense) with more advanced capabilities. For example, it narrows down the list of suggestions based on your typing, adds parentheses when completing method names, completes variable and field names depending on their types, and so on.

Symbol Code Completion (C# only)

Use Ctrl + Space for completing C# variables and methods, currently visible type names, C# keywords, and more. ReSharper can also automatically suggest prefixes when declaring identifiers, according to your coding guidelines.

Smart Code Completion

Smart Code Completion, invoked with Ctrl + Shift + Space, filters the list of methods and variables to match the expected type of an expression. For example, when you use Smart Completion for method call arguments, the list of suggested values is narrowed down only to the required parameter type.

Type Name Completion

Type Name Completion is invoked with Ctrl + Alt + Space. Unlike basic completion (which only completes types accessible at the current location), ReSharper completes the names of types available in the current project, and automatically adds the appropriate namespace import directives when necessary.

Context actions

Context actions are intended for local code transformations that you may want to perform in a certain context. ReSharper automatically indicates when one or more context actions are available at the current caret position with the yellow light bulb screenshot to the left of the code line. Context actions are applied just like quick-fixes. You can either click the bulb or press Alt + Enter, and then select the desired action.

Context action for concatenated string

Generated format string

Context action for splitting declaration and assignment

Declaration split from assignment

Context actions can be disabled and enabled via the Options dialog.

Quick Documentation Lookup

To see the documentation for a certain class, function or other symbol right in the editor, position the caret on the symbol name and press Ctrl + Q. The documentation shows in a popup window with clickable links to other resources.

Parameter Info

This part of Visual Studio's IntelliSense is also extended in ReSharper. When you call a method, it shows you all possible method signatures and parameters with relevant documentation (the tooltip appears automatically while you type, or you can display it by pressing Ctrl + P). While you are adding new arguments, ReSharper grays out all incompatible signatures.

Parentheses Matching

Matching parentheses/brackets/braces are highlighted whenever you place the caret immediately before/after the closing character (in C#). In Visual Basic, the matching Sub or Function are highlighted when the caret is placed anywhere within or after End Sub or End Function. Similarly, the matching parenthesis/bracket/brace is highlighted whenever you place the caret immediately before/after an opening character (this option is configurable).

•  

•  

Parentheses and Quotes Auto-Insertion

When you type (, [, ", or ' in the editor, a paired character is inserted automatically (whenever appropriate). This feature may be easily switched off, but you don't be afraid of inserting too many closing parentheses, brackets, or quotes by mistake: ReSharper will recognize the closing parenthesis or quote already exists and will leave only one character printed.

Comment/Uncomment Code

Promptly comment or uncomment any block of C# or Visual Basic code by selecting it in the editor and pressing Ctrl + / (for line comment) or Ctrl + Shift + / (for block comments in C#).

You can also use Ctrl + / to quickly comment or uncomment the line of code where the caret is located in the editor if no block code has been selected. In the same circumstance, pressing Ctrl + Shift + / inserts the opening block comment /* and the closing block comment */ immediately before and immediately after the caret's position, or removes them if the caret is positioned inside the commented code block.

Extend/Shrink Selection

Extend Selection feature allows the user to successively select expanding blocks of code so that you may easily select any expression in the code by placing the caret somewhere inside it and pressing Ctrl + W a few times. Shrink Selection works in the opposite way and can be applied by pressing the Ctrl + Shift + W shortcut.

Duplicate Line/Block

Quickly duplicate any line (block) of code by placing the caret at this line in the editor (respectively, selecting the desired block) and pressing Ctrl + D.

Code Completion

ReSharper complements and extends Visual Studio's native code completion (IntelliSense) with more advanced capabilities. For example, it narrows down the list of suggestions based on your typing, adds parentheses when completing method names, completes variable and field names depending on their types, and so on.

Matching parentheses/brackets/braces are highlighted whenever you place the caret immediately before/after the closing character. Similarly, the matching parenthesis/bracket/brace is highlighted whenever you place the caret immediately before/after an opening character (this option is configurable).

If the matching piece of code scrolls off the screen, an appropriate popup appears for your convenience.

When you type (, [, ", or ' in the editor, a paired character is inserted automatically (whenever appropriate).

Smart Code Completion

For example, when you use Smart Completion for method call arguments, the list of suggested values is narrowed down only to the required parameter type.
