Question

I’m trying to write a validation to check that an Object instance can be cast to a variable Type. I have a Type instance for the type of object they need to provide. But the Type can vary. This is basically what I want to do.

        Object obj = new object();         Type typ = typeof(string); //just a sample, really typ is a variable          if(obj is typ) //this is wrong 'is' does not work like this         {             //do something         } 

The type object itself has the IsSubClassOf, and IsInstanceOfType methods. But what I really want to check is if obj is either an instance of typ or any class derived from typ.

Seems like a simple question, but I can’t seem to figure it out.

Answer 1

How about this:

      MyObject myObject = new MyObject();     Type type = myObject.GetType();      if(typeof(YourBaseObject).IsAssignableFrom(type))     {          //Do your casting.        YourBaseObject baseobject = (YourBaseObject)myObject;     }     

This tells you if that object can be casted to that certain type.
