Creating a method with a reference argument.

    
using  System;
class  MainClass  {
        static  void  Main()  {
                int  x  =  10;

                Console.WriteLine("Before  calling  non-ref  function,  x  =  {0}",  x);
                NonRefFunction(x);
                Console.WriteLine("After  calling  non-ref  function,  x  =  {0}",  x);
                RefFunction(ref  x);
                Console.WriteLine("After  calling  ref  function,  x  =  {0}",  x);
        }

        static  void  NonRefFunction(int  x)  {
                Console.WriteLine("Top  of  NonRefFunction.  X  =  {0}",  x);
                x  =  x  +  10;
                Console.WriteLine("Bottom  of  NonRefFunction.  X  =  {0}",  x);
        }

        static  void  RefFunction(ref  int  x)  {
                Console.WriteLine("Top  of  RefFunction.  X  =  {0}",  x);
                x  =  x  +  10;
                Console.WriteLine("Bottom  of  RefFunction.  X  =  {0}",  x);
        }
}
