C Sharp Type Comparison
From Leo's Notes
Last edited on 2 June 2013, at 04:59.
When comparing object/class types, rather than using typeof(), use TypeHandle.
RuntimeTypeHandle t1 = typeof(ClassName).TypeHandle;
RuntimeTypeHandle t2 = Type.GetTypeHandle(objectName);
if (t1.Equals(t2)) {
// they are the same type
}
The justification is that TypeHandle is a wrapper around an unmanaged pointer to the type which can be compared directly rather than creating the Type object in the case of the 'is' operator.
