Marshal.GetTypeLibVersionForAssembly Method (Assembly, Int32, Int32)


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)

public static void GetTypeLibVersionForAssembly(
	Assembly inputAssembly,
	out int majorVersion,
	out int minorVersion


Type: System.Reflection.Assembly

A managed assembly.

Type: System.Int32

The major version number.

Type: System.Int32

The minor version number.

inputAssembly is null.

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.
