I am trying to inherit from MessageBox and i get error in
compilation time.

The code is:
public class MyMessageBox : MessageBox
{
public static DialogResult Show(int errorCode)
{
return DialogResult.OK;
}
}

The error is:
System.Windows.Forms.MessageBox.MessageBox() is
inaccessible due to its protection level

I guess it because the constructor of MessageBox is privte.
My question is, is there anyway to inherit from messagebox?

Thanks,
Adam

No. Unless a class has at least one protected or public (or internal if
you're in the same assembly) constructor, you can't inherit from it (in
C# at least).

No, the class has only a private constructor, so you can't derive from nor create an instance of the class.
