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.

To invoke smart code completion
  1. Place the caret at the position where you're going to type your code.
  2. Press Ctrl+Shift+SpaceCtrl+Alt+Space.

Note

The Use CamelHumps check box on the Editor page of the Options dialog box doesn't have any impact on how CamelHumps works in completion.

Since ReSharper 8.0 smart completion items are included in basic completion list. All appropriate types or symbols are displayed and have higher priorities in basic completion list. But you can still invoke smart completion in order to get a short list of suitable items.

You can use the following examples to get an idea of how Smart Code Completion works with various code items:

After a return statement

Coding_Assistance__Code_Completion__Smart__smart_return

In the right-hand side of assignments

Coding_Assistance__Code_Completion__Smart__smart_dot

In cast expressions

Before:

Coding_Assistance__Code_Completion__Smart__smart_cast_01

After launching Smart Completion (since there's a single option in this case, ReSharper inserts the expected type without displaying a drop-down list):

Coding_Assistance__Code_Completion__Smart__smart_cast_02

In object initializers

ReSharper provides Smart Completion for setting properties in object initializers that were not previously set for a particular object:

Coding_Assistance__Code_Completion__Smart__object_initializer

In lambda expressions

In addition to traditional anonymous and named methods, Smart Completion readily generates lambda-expression syntax:

Coding_Assistance__Code_Completion__Smart__lambdas

Creating a local variable in place of an out parameter

Coding_Assistance__Code_Completion__Smart__local_variable

Using camelhumps

Coding_Assistance__Code_Completion__Smart__CamelHumps
