What is the C# equivalent of VB.Net's

VB Code:
  1. MyBase.New(...)

??

I'm inheriting from ApplicationException and the normal practice in VB.net is to call the the base class constructor from within the derived class's constructor.

At the moment I have this, where I have shown the line I want to change...

Code:
public class SudokuGridIllegalException : ApplicationException 
{
	//constructor of my derived class
	public SudokuGridIllegalException(String message)
	{
		// call the base's constructor
		/* wrong */ mybase.New(message);
	}
}
Is this even the way you do this in C#? *noobz*
