dtOne
-------------------------

--------------------------
 101  |  ABC
 102  |  XYZ
 103  |  MNO
---------         


        

Answer 1

TO get it work its better to use Linq To DataSet will resolve it easily..

DataTable table1= ds.Tables["table1"];
DataTable table2= ds.Tables["table2"];
var diff= table1.AsEnumerable().Except(table2.AsEnumerable(),
                                                    DataRowComparer.Default);

Answer 2

Starting with the solution showed under LINQ query on a DataTable, I'd try it with:

var dtOneData = from myRow in dtOne.AsEnumerable();
var dtTwoData = from myRow in dtOne.AsEnumerable();
var difference = dtOneData.Except(dtTwoData);
