    When you say

    string a;

    a _is_ a reference. Perhaps if you would give more information about
    what you hope to do with string references, we could give you more
    help.

    By the way, if what you want is to pass a string into a method, and
    upon return have it change to a different string, you can do this using
    ref:

    private void MyMethod(ref string x)
    {
        x = "Goodbye";
    }

    string a = "Hello";
    MyMethod(ref a);
    // At this point a will be "Goodbye".
