Isn't MyClass just something like

public class MyObject {
public virtual void DoSomething() {
Console.WriteLine("I did something!");
}

public void Process() {
((MyObject)this).DoSomething(); // MyClass.DoSomething()
}
}

?

No - just casting doesn't remove the fact that the call is made polymorphically. (i.e. if a subclass overrides DoSomething, then calls Process, it's the subclass's version of DoSomething which will be called.)

Wow, I did not realize that... Is there any way to actually call this classes method instead of the overriden one?

# Jon Skeet said on March 12, 2004 9:45 AM:

Only by making it non-virtual.

Is there a reason this was added to VB.NET and not C#? I looked at the difference between the code, the VB.NET IL does a call MyObject.Process while the C# IL does a callvirt MyObject.Process

Obvious why this happens, but what about adding it to C#, or is a bad feature to have? I have never used it, just wondering why ...

Do you know if MyClass is something that the VB team went out of their way to provide by doing lots of work or is this natively supported in CIL?

Adam :
You can use "base" but you need a new class :)

public class YourObject : MyObject {
public void Process() {
base.DoSomething(); // base and this make a lot of difference here
}
}

public class HisObject : YourObject {
public override void DoSomething() {
Console.WriteLine("Process never calls it!");
}
