Check if instance is of a type

Question

Using this to check if c is an instance of TForm.

c.GetType().Name.CompareTo("TForm") == 0

Is there a more type safe way to do it besides using a string as a param to CompareTo()?

A little more compact than the other answers if you want to use c as a TForm:

if(c is TForm form){
    form.DoStuff();
}
