Question

Is there a way to get code like this print “Test”;

DecendedTextBox myControl = new DecendedTextbox();

if (myControl is "TextBox")
{
   Debug.WriteLine("Test");
}

The point here is that I need to see if myControl inherits from a type that I don’t have a reference to at Compile Time.

If you don’t have a reference to the type, you can do this:

DecendedTextBox myControl = new DecendedTextbox();

if (myControl.GetType().Name == "TextBox")
{
   Debug.WriteLine("Test");
}

If you want to know the full type name, including namespace, you can use GetType().FullName

As far as checking to see if it inherits from the type, something like this:

DecendedTextBox myControl = new DecendedTextbox();
Type typeToCheck = Type.GetType("TextBox");
if (myControl.GetType().IsSubclassOf(typeToCheck))
{
   Debug.WriteLine("Test");
}

Note that Type.GetType takes an AssemblyQualifiedName, so you’ll need to know the full type name.
