Marshal.GetTypeLibVersionForAssembly Method

Retrieves the version number of a type library that will be exported from the specified assembly.

Namespace:  System.Runtime.InteropServices
Assembly:  mscorlib (in mscorlib.dll)

static member GetTypeLibVersionForAssembly : 
        inputAssembly:Assembly * 
        majorVersion:int byref * 
        minorVersion:int byref -> unit 


Type: System.Reflection.Assembly
A managed assembly.
Type: System.Int32%
The major version number.
Type: System.Int32%
The minor version number.


inputAssembly is a null reference (Nothing in Visual Basic).

Before exporting an assembly by using TypeLibExporterFlags with the CallerResolvedReferences value, you can use this method to retrieve the type library version from the assembly.

If you do not apply the TypeLibVersionAttribute attribute to an exported assembly to explicitly control the version number of the generated type library, the type library will have the same version number as the assembly.
