    string[,] cmdArr = new string[2,3] {
    {"quit | exit", "Ends the program."},
    {"list", "Prints out the current text list."},

    [WebMethod]
    public Tool[] getToolList(string s)
    {

    Tool[] a = new Tool[2];

    Tool a[0]=new Tool();
    // the above throws an error. WHY?

    a[0].ToolID = "1";
    a[0].Description = "TOOL1";

    a[1].ToolID = "2";
    a[1].Description = "TOOL2";

    // Console.WriteLine(a[0]);

    return a;
    }

    public class Tool
    {
    public string ToolID;
    public string Description;
    }
