Import Symbol Completion

ReSharper | Edit | Import Symbol

This command suggests types and extension methods from modules referenced in the current project regardless of whether their namespaces are imported in the current file. The namespace of each suggested item is displayed on its right in the suggestion list. As soon as you select a non-imported type, the required namespace import directives are added automatically.

By default, import symbol completion items in C# and VB.NET are included into the suggestion lists of automatic and basic completion. If you want to change the default behavior, use the corresponding controls on the Environment | IntelliSense | Completion Behavior page of ReSharper options.

Invoke import symbol completion

  1. Place the caret at the position where you're going to type your code.

  2. Press Control+Alt+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 import symbol 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 page of ReSharper options).

Exclude items from completion suggestions

You may want some types or namespaces not to be suggested, for example, if you have something similar to a system type in your solution, say MyFramework.MyCollections.List, but you are not actually using it. To exclude such symbols from the suggestions, add them to the Exclude from import and completion list on the Code Inspection | Settings | Auto Import page of ReSharper options (Alt+R, O). The format of the entries is Fully.Qualified.Name, Fully.Qualified.Name.Prefix*, or *Fully.Qualified.Name.Suffix. Generic types are specified as List`1.
