Smart Code Completion filters the list of types, methods, and variables to match the expected type of an expression. It works anywhere as long as ReSharper can determine the expected type of the expression, for example, right-hand sides of assignments, variable initializers, or return statements. If several return types are possible, ReSharper detects the most recently used symbol of an applicable type and automatically selects it in the lookup list. Smart Completion can also suggest creating anonymous delegates, lambda expressions, and regular methods, as well as local variables for out parameters. In addition to that, in object initializers, Smart Completion suggests fields/properties that were not yet assigned a value.
- Place the caret at the position where you're going to type your code.
- Press Ctrl+Shift+Space.
TipTo make sure that CamelHumps works with Code Completion, clear the Case-sensitive prefix matching check box in ReSharper | Options | Environment | IntelliSense | Completion Behavior. Note that the Use CamelHumps check box in ReSharper | Options | Environment | Editor doesn't have any impact on how CamelHumps works in completion.
You can use the following examples to get an idea of how Smart Code Completion works with various code items:
After a return statement
In the right-hand side of assignments
After "new" keyword
In cast expressions
In object initializers
In lambda expressions
Creating a local variable in place of an out parameter
After a Return Statement
In the Right-Hand Side of Assignments
After "new" Keyword
In Cast Expressions
After launching Smart Completion (since there's a single option in this case, ReSharper inserts the expected type without displaying a drop-down list):
In Object Initializers
ReSharper provides Smart Completion for setting properties in object initializers that were not
previously set for a particular
In Lambda Expressions
In addition to traditional anonymous and named methods, Smart Completion readily generates
Creating a Local Variable in Place of An Out Parameter
Suppose that you typed the following code:
- Press Ctrl+Shift+Space or choose ReSharper | Edit | Smart Code Completion.
The following drop-down list appears:
- Choose the appropriate method from the list and press Enter:
The caret is placed so that you can resume typing the tag code.
