ReSharper 2022.1 Help

Import Symbol Completion

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, smart completion items in C# and VB.NET are included in 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 basic completion

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

  2. Press Control+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.

When you use code completion over existing code items, you can either insert the selected completion suggestion before the existing item by pressing Enter or replace the existing identifier with the selected suggestion by pressing Tab. If necessary, you can change the default shortcuts on the Environment | IntelliSense | Completion Characters page of ReSharper options (Alt+R, O).

Exclude types and namespaces 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 items from the suggestions, add them to the Exclude from import and completion list on the Code Editing | Type 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.
