Refactored to try to pass a 2 dime array by reference

CD "c:\users\pagan\documents\visual studio 2010\projects\glwebservice\glwebservice\bin\debug"
ACTIVATE WINDOW watch
SET STEP ON 
lows = CREATEOBJECT("glwebservice.glclient")
lows.login("mquigley@sba-list.org", "Sbalist123!", "RUIbS9BPsZ7TkyCRCl6B89Gi")
DIMENSION foo(4,2)


foo(1,1)="dan@primarydatasolutions.com"
foo(2,1)="charleshankey@f1tech.com"
foo(3,1) = "raferris@hsonline.net"
foo(4,1) = "foo@foo.net"
foo(1,2) = 0
foo(2,2) = 0
foo(3,2) = 0
foo(4,2) = 0
comarray(lows,0)

* doesn't this pass the array by reference ???

=lows.FindIdsByEmails(@foo)

lows.logout
lows = null

RETURN

Here is the refactored C# - once again works like a charm inside C# test harness

        public void FindIdsByEmails(object[,] emailarray)
        {
            int emailslen = emailarray.GetLength(0);

            for (int i = 0; i < emailslen; i++)
            {
                string email = (string)emailarray[i,0];
                long? id = this.FindIdByEmail(email);

                
                if (id != null)
                {
                    emailarray[i, 1] = id;
                }
                else
                {
                    emailarray[i, 1] = 00000;
                }
            }
        }
