Answer 1

simply return null value in the else statement in the calling method compare the return value if is null give the access id denied message (or) you create the one dataset which contain the this error message as follows and return that value

 DataSet ds = new DataSet();
        DataTable dt = new DataTable("msg");
        DataColumn dc = new DataColumn("col1");
        dc.DataType = typeof(string);
        dc.ColumnName = "msg";
        dt.Columns.Add(dc);
        ds.Tables.Add(dt);
        DataRow dr = dt.NewRow();
        dr[0] = "Access is denied";
        ds.Tables["msg"].Rows.Add(dr);
        return ds;
