Name Property (Renderer)

Summary

Gets the renderer's unique name.

Syntax

C++

public string Name {get;}

Public ReadOnly Property Name As String

public: 
property String^ Name { 
   String^ get(); 
}

Property Value

A string that represents the renderer's unique name

Remarks

The returned string can be used to uniquely identify a renderer. A program can save this value to persistent storage and use it later with the Renderers.IndexOf method to locate and restore the renderer selection.
