Brian Keller posed a question to the readers of his blog asking what we thought, if there were such a thing, the “that” keyword should do in C#. What a fantastic idea! My suggestion – the that keyword would be used to allow access to inherited classes from the base class. IE:

public class MyBase
{
    public MyBase()
    {
 	//only call CallToMethod() in a specific class
 	if( typeof(that).ToString().Equals("MyChild") )
 		that.CallToMethod();
    }
}

public class MyChild : MyBase
{
    public void CallToMethod()
    {
        // more code goes here...
    }
}

Yeah I know it’s really dangerous and would definitely have some overhead associated with it but the functionality would be awesome!
