Answer 1

@Prem: Use this code its working fine, check it out.

var combinedrows = from dt1 in DsResults.Tables[0].AsEnumerable()
                              join dt2 in DsResults.Tables[1].AsEnumerable() on        dt1.Field("MethodName") equals dt2.Field("MethodName")
                           select new { sp = dt1.Field("Tab1_col1"), Method = dt1.Field("MethodName"), _class = dt1.Field("Class"),
                                        BLLMethod = dt1.Field("Tab2_col2")
                           }; 


        DataTable finaldt = new DataTable("FinalTable");
        finaldt.Columns.Add(new DataColumn("sp", typeof(string)));
        finaldt.Columns.Add(new DataColumn("Method", typeof(string)));
        finaldt.Columns.Add(new DataColumn("Class", typeof(string)));
        finaldt.Columns.Add(new DataColumn("BLLMethod", typeof(string)));
        DataRow newrow = finaldt.NewRow();           
        foreach (var row in combinedrows)
        {
            DataRow dr = finaldt.NewRow();
            dr["sp"] = row.sp;
            dr["Method"] = row.Method;
            dr["Class"] = row._class;
            dr["BLLMethod"] = row.BLLMethod;
            finaldt.Rows.Add(dr);
        }
