Gets the unique identifier of the reference.

Namespace: VSLangProj80
Assembly: VSLangProj80 (in VSLangProj80.dll)

Syntax

'Declaration
ReadOnly Property Identity As String

string Identity { get; }

property String^ Identity {
    String^ get ();
}

abstract Identity : string

function get Identity () : String

Property Value

Type: System.String
The returned string depends on the reference type.

Reference Type	Value Returned
Assembly	Assembly name (assembly name without path or extension)
COM	The 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.
Native	Assembly identity of the assembly being referenced.

Assembly

Assembly name (assembly name without path or extension)

COM

The 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.

Native

Assembly identity of the assembly being referenced.

Implements

Reference2.Identity

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.

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.
