Reference3.Identity Property

Definition

Namespace:

VSLangProj80

Assembly:

Microsoft.VisualStudio.Interop.dll

Gets the unique identifier of the reference.

public:
 property System::String ^ Identity { System::String ^ get(); };

public:
 property Platform::String ^ Identity { Platform::String ^ get(); };

[System.Runtime.InteropServices.DispId(7)]
public string Identity { [System.Runtime.InteropServices.DispId(7)] get; }

[<get: System.Runtime.InteropServices.DispId(7)>]
member this.Identity : string

Public ReadOnly Property Identity As String

Property Value

String

The returned string depends on the reference type.Reference TypeValue ReturnedAssemblyAssembly name (assembly name without path or extension)COMThe format is:"GUID\major.minor\localeid\wrappertool"For example,"{00000205-0000-0010-8000-00AA006D2EA4}\2.5\409\tlbimp"is returned for ActiveX Data Objects 2.5.NativeAssembly identity of the assembly being referenced.

Implements

Identity

Attributes

DispIdAttribute

Examples

This example adds an Assembly and a COM reference to an open Visual Basic or Visual C# project and displays the Identity property for each. To run this example as an add-in, see How to: Compile and Run the Automation Object Model Code Examples.

The default paths for the reference added are: <installation root>\Program Files\Microsoft.NET\Primary Interop Assemblies for adodb.dll, and <installation root>\Program Files\Common Files\SpeechEngines\Microsoft for spcommon.dll. Replace <file path> in the example with these or other appropriate file paths.

Remarks

All components have a unique identifier. The Identity property gets that information. This property is unique for each reference, as an exception is raised if you attempt to add a reference with the same identity as a reference that is already in the collection. This property is suitable for indexing the Reference3 collection by using the Item method.
