I have to add row value to particular column depending on flag.getting error as
Unable to cast object of type 'System.Data.DataRow' to type 'System.IConvertible'.Couldn't store <system.data.datarow> in AMOUNT Column. Expected type is Decimal.

What I have tried:

C#

DataTable dt = new DataTable();
         dt.Columns.AddRange(new DataColumn[5] {
 new DataColumn("AMOUNT", typeof(decimal)),
 new DataColumn("DUE DATE", typeof(string)),
  new DataColumn("PAYMENT DATE", typeof(decimal)),
 new DataColumn("EMI RECEIVED", typeof(decimal)),
 new DataColumn("OD CHRGS RECEIVED", typeof(decimal))
});
           //dt.Columns.Add("DATE", typeof(string));
           // dt.Columns.Add("DUE AMOUNT", typeof(decimal));
           // dt.Columns.Add("PAYMENT", typeof(decimal));
           // dt.Columns.Add("OD CHRGS RECEIVED", typeof(decimal));

         DataRow dr;
         dr = dt.NewRow();
            for (int i = 0; i < dsreq.Tables[0].Rows.Count; i++)
            {

                dr["AMOUNT"] = dt.Rows.Add(dsreq.Tables[0].Rows[i]["AMT"]);
                if (dsreq.Tables[0].Rows[i]["FLAG"].ToString() == "D")
                {
                    dr["DUE DATE"] = dt.Rows.Add(dsreq.Tables[0].Rows[i]["DATE1"].ToString());
                }
                else
                {
                    dr["PAYMENT DATE"] = dt.Rows.Add(dsreq.Tables[0].Rows[i]["DATE1"].ToString());
                }
                dr["EMI RECEIVED"] = dt.Rows.Add(dsreq.Tables[0].Rows[i]["INSTALLMENT AMOUNT"]);
                dr["OD CHRGS RECEIVED"] = dt.Rows.Add(dsreq.Tables[0].Rows[i]["AFC/OTHER AMOUNT"]);

try this

C#

for (int i = 0; i < dsreq.Tables[0].Rows.Count; i++)
           {
               DataRow  dr = dt.NewRow();
               dr["AMOUNT"] = Convert.ToDecimal(dsreq.Tables[0].Rows[i]["AMT"]);
               if (dsreq.Tables[0].Rows[i]["FLAG"].ToString() == "D")
               {
                   dr["DUE DATE"] = dsreq.Tables[0].Rows[i]["DATE1"].ToString();
               }
               else
               {
                   dr["PAYMENT DATE"] = Convert.ToDecimal(dsreq.Tables[0].Rows[i]["DATE1"].ToString());
               }
               dr["EMI RECEIVED"] = Convert.ToDecimal(dsreq.Tables[0].Rows[i]["INSTALLMENT AMOUNT"]);
               dr["OD CHRGS RECEIVED"] = Convert.ToDecimal(dsreq.Tables[0].Rows[i]["AFC/OTHER AMOUNT"]);
               dt.Rows.Add(dr);
           }

cast the values based on the type defined in the table column
