    When would be the best time in your own opinion to use the ref in C#? :) "To teach is to learn twice"

      When you need to modify the source variable rather than a copy of it. Example:

      void Test()
      {
      string str="UnModified";
      RefTest(ref str);
      //str now == "Modified!"
      }

      void RefTest(ref string s)
      {
      s="Modified!";
      }

      "Blessed are the peacemakers, for they shall be called sons of God." - Jesus
      "You must be the change you wish to see in the world." - Mahatma Gandhi
