Public DataSet GetDataSet (string v_strConn) {SqlConnection conn = new SqlConnection (v_strConn); string strSql = "Select * from tbClass; Select * from tbBoard "; // create the SqlDataAdapter object SqlDataAdapter da = new SqlDataAdapter (strSql, conn); DataSet dt = new DataSet (); DataTableMapping dtmClass = da. tableMappings. add ("Table", "Forum category Table"); dtmClass. columnMappings. add ("ClassID", "category ID"); dtmClass. columnMappings. add ("ClassName", "category name"); DataTableMapping dtmBoard = da. tableMappings. add ("Table1", "forum table"); dtmBoard. columnMappings. add ("BoardID", "Forum ID"); dtmBoard. columnMappings. add ("BoardName", "Forum name"); dtmBoard. columnMappings. add ("BoardClassID", "category ID"); da. fill (dt); return dt ;}
