System.Web.Services. Protocols.SoapException: Server was unable to process request. ---> System.InvalidOperationException: There was an error generating the XML document. ---> System.InvalidOperationException: Cannot serialize the DataTable. DataTable name is not set.

below is my webservice's code for fetching.

    [WebMethod]
    public DataTable Select_Employee_By_Sno(string Emp_Code)
    {
        Business_Logic bl = new Business_Logic();
        DataTable dt = new DataTable();
        dt= bl.Select_Employee_By_Sno(Emp_Code);
        return dt;
    }
