Type Asserts (NUnit 2.2.3)

These methods allow us to make assertions about the type of an object.

Assert.IsInstanceOfType( Type expected, object actual );
Assert.IsInstanceOfType( Type expected, object actual, 
                string message );
Assert.IsInstanceOfType( Type expected, object actual, 
                string message, params object[] parms );
				
Assert.IsNotInstanceOfType( Type expected, object actual );
Assert.IsNotInstanceOfType( Type expected, object actual, 
                string message );
Assert.IsNotInstanceOfType( Type expected, object actual, 
                string message, params object[] parms );
			
Assert.IsAssignableFrom( Type expected, object actual );
Assert.IsAssignableFrom( Type expected, object actual, 
                string message );
Assert.IsAssignableFrom( Type expected, object actual, 
                string message, params object[] parms );
				
Assert.IsNotAssignableFrom( Type expected, object actual );
Assert.IsNotAssignableFrom( Type expected, object actual, 
                string message );
Assert.IsNotAssignableFrom( Type expected, object actual, 
                string message, params object[] parms );
