Type.IsCOMObject Property
Assembly: mscorlib (in mscorlib.dll)
This method returns false for COM interfaces because they are not objects. COM interfaces can be implemented by Microsoft .NET Framework objects.
You can also load a COM class and get a Type object for that COM class by using the [<topic://cpgrftypelibraryimportertlbimpexe>] tool.
If the current Type represents a constructed generic type, this property applies to the generic type definition from which the type was constructed. For example, if the current Type represents MyGenericType<int> (MyGenericType(Of Integer) in Visual Basic), the value of this property is determined by MyGenericType<T>.
If the current Type represents a type parameter in the definition of a generic type or generic method, this property always returns false.
The following example shows a use of the IsCOMObject property.
public ref class MarshalWrapper { public: [SecurityPermissionAttribute(SecurityAction::Demand, Flags=SecurityPermissionFlag::UnmanagedCode)] void MarshalMethod() { Object^ obj; obj = Marshal::GetActiveObject( "Excel.Application" ); if ( Marshal::IsComObject( obj ) ) { Marshal::ReleaseComObject( obj ); } } };
