Compare current DataTable row with previous using C# in ASP.Net

Hi @Mudassar,

Thanks for your reply. I have solved my issue with the below code

                                DataTable dt_Chk_First_Table =  Chk_Current_Data;
                                DataTable dt_Chk_Second_Table =  Chk_Current_Data;                             

                                decimal Current_Prcnt_Climing = 0;                              
                                decimal Currnt_Suply_Qty = 0;                              

                                for (int l = 0; l <= dt_Chk_First_Table.Rows.Count - 1; l++)
                                {                                   
                                    Current_Prcnt_Climing = Convert.ToDecimal(dt_Chk_First_Table.Rows[l]["Prcnt_Claim"].ToString());
                                    Currnt_Suply_Qty = Convert.ToDecimal(dt_Chk_First_Table.Rows[l]["Suply_Qty"].ToString());
                                    decimal Remaing_Claimng = 100 - Current_Prcnt_Climing;
                                 

                                    for (int m = 0; m <= dt_Chk_Second_Table.Rows.Count - 1; m++)
                                    {
                                        decimal Chk_Prcnt_Claim = Convert.ToDecimal(dt_Chk_Second_Table.Rows[m]["Prcnt_Claim"].ToString());
                                        decimal Chk_Suply_Qty = Convert.ToDecimal(dt_Chk_Second_Table.Rows[m]["Suply_Qty"].ToString());

                                        if ((Currnt_Suply_Qty == Chk_Suply_Qty) && (Remaing_Claimng == Chk_Prcnt_Claim))
                                        {
                                            dt_Chk_Second_Table.Rows[l].Delete();
                                            dt_Chk_Second_Table.Rows[m].Delete();
                                            dt_Chk_Second_Table.AcceptChanges();                                           
                                            break;
                                        }
                                    }
                                }                               
                                DataTable dt_Chk_Trns = dt_Chk_Second_Table;
