This is sample LINQ method syntax join where single column used in join condition.
DataTable _dtMaster = dt();
_dtMaster.Columns.Add("Discription");
DataTable _dtChild = dttt();
_dtMaster.AsEnumerable().Join(_dtChild.AsEnumerable(), _dtmater => Convert.ToString(_dtmater["id"]),
_dtchild => Convert.ToString(_dtchild["id"]), (_dtmater, _dtchild) => new { _dtmater, _dtchild }).ToList().ForEach(o=>o._dtmater.SetField("Discription",o._dtchild["Discription"].ToString()));
Please tell me how to mention multiple columns in join when i will follow above approach method syntax?
please give me a sample code using above approach kind of LINQ where multiple columns will be used in join.
Thanks
