Introduce Alias

Introduces a new file-scoped alias for the current type or namespace name, and replaces it with the newly-created alias.

Availability

Available from the context menu or via shortcuts:

• when the caret is on a reference to a type. This reference should contain namespace information.

Notes

• When applying this refactoring, you can choose whether to create an alias for the namespace where the referenced type is, or for the entire type reference.
• Once an alias has been created, Rename is automatically invoked, so you can provide a proper alias name.
• If you want to replace all matching references with the newly declared alias, use the Introduce Alias (replace all) refactoring.
• This refactoring is the opposite of Replace with Alias.

Example

C#

using System;

namespace MyApplication
{
    class TestClass
    {
        private │System.Drawing.Rectangle MyRec = new System.Drawing.Rectangle();
    }
}

VB.NET

Namespace MyApplication
    Public Class TestClass
        Private MyRec As │System.Drawing.Rectangle = New System.Drawing.Rectangle()
    End Class
End Namespace

Result:

C#

using System;
using RectangleAlias = System.Drawing.Rectangle;

namespace MyApplication
{
    class TestClass
    {
        private │RectangleAlias MyRec = new RectangleAlias();
    }
}

VB.NET

Imports RectangleAlias = System.Drawing.Rectangle
Namespace MyApplication
    Public Class TestClass
        Private MyRec As │RectangleAlias = New RectangleAlias()
    End Class
End Namespace
