Basic Completion

ReSharper | Edit | Complete Symbol
Ctrl+Space
ReSharper_CompleteCodeBasic

ReSharper's basic completion suggests names of classes, methods, variables, keywords, and any other symbols that are available within the current visibility scope including extension methods that were previously imported. Many other context-specific suggestions, like live templates, code generation suggestions, unit test categories are also available in the completion list.
By default, suggestions of basic completion also include items from Smart Completion and Import Symbol Completion. If you want to change the default behavior, use the corresponding controls on the Environment | IntelliSense | Completion Behavior options page The list of suggestions is similar to that of Automatic Completion.

To invoke basic completion

  1. Place the caret at the position where you're going to type your code.
  2. Press Ctrl+Space.
  3. Select a suggestion from the list and press Enter or start typing the initial letters of the identifier or its CamelHumps abbreviation to narrow down the list of suggestions.

You can also invoke basic completion on an existing identifier. In this case, there are two ways to apply the selected completion suggestion; press Enter to insert it and leave the existing item or press Tab to replace the existing item (If necessary, you can change the default shortcuts on the Environment | IntelliSense | Completion Characters options page).

Examples of basic completion

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

Suggesting type-based variable names

Commonly used names for fields and variables are suggested depending on their type. After entering the type of a variable, press Ctrl+Space. The look-up list displays the suggested names:

Coding_Assistance__Code_Completion__Symbol__01

If you enter a variable name prefix, ReSharper will append it to each suggested name:
Coding_Assistance__Code_Completion__Symbol__02

You can specify a prefix and/or a suffix for all new variable names in Options | Code Editing | C# | C# Naming Style. If you do that, completion items will be modified accordingly:
Coding_Assistance__Code_Completion__Symbol__06

Suggesting members of a class

Coding_Assistance__Code_Completion__Symbol__03

Suggesting visible types

Coding_Assistance__Code_Completion__Symbol__04

Suggesting c# keywords

Coding_Assistance__Code_Completion__Symbol__05

Suggesting this keyword for static methods in static classes

Coding_Assistance__Code_Completion__Symbol__this

Completion for enum members

Coding_Assistance__Code_Completion__Symbol__enum_members_01
Coding_Assistance__Code_Completion__Symbol__enum_members_02

Basic completion using camelhumps

Coding_Assistance__Code_Completion__Symbol__07

Completion for unresolved symbols

Early used names of data types and their members are suggested, even if they are not declared anywhere in the code and cannot be resolved.

Coding_Assistance__Code_Completion__Symbol__unresolved

Completion for argument names

Coding_Assistance__Code_Completion__Argument_names

Suggesting members of a dynamic type

Coding_Assistance__Code_Completion__Dynamic_members

Suggesting existing partial classes

When you type partial class, names of partial classes in the current scope are added to the suggestions list, thus helping you to quickly create new parts of existing partial classes.
