Dim value As String
 
value = instance.Name

public string Name {get;}

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

The device name.

The returned string can be used to uniquely identify a device. A program can save this value to persistent storage and use it later with the Devices.IndexOf and Devices.Selection methods to restore the device's selection.
