Question

I have two data tables as follows

dtOne
-------------------------
  ID  |   Name 
--------------------------
 101  |  ABC
 102  |  XYZ
 103  |  MNO
--------------------------

dtTwo
-------------------------
  ID  |   Name 
--------------------------
 101  |  ABC
 102  |  XYZ
--------------------------

I just want the result as data which is in dtOne and not in dtTwo (dtOne-dtTwo)

dtResult
-------------------------
  ID  |   Name 
--------------------------
 103  |  MNO
--------------------------

How can i achieve this .

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);
