datatable loop values into another datatable in c# ?

Hi,

I want to get the values from datatable through loop and add it to another datatable.

I have a code that adds the current row on every iteration. If anybody knows, Let me know with example Code..

Sample_Code:

string ChartQry = "SELECT A.TransDate,concat(DATE_FORMAT(a.transtime,'%h:%00 %p'),'-',DATE_FORMAT(a.transtime,'%h:59 %p')) as Hour,DATE_FORMAT(a.transtime,'%H') as TimeGroup,Date_format(TransTime,'%y-%m-%d %H:00:00') as DateTime, Sum(B.TaxableAmount+B.TaxAmount1+B.TaxAmount2+B.TaxAmount3+B.TaxAmount4+B.TaxAmount5+B.TaxAmount6) As Amount, DATE_FORMAT(a.transtime,'%h:%00 %p') as TM FROM " + Branch_AliasName + ".Trans A JOIN " + Branch_AliasName + ".TransDetail B on A.Transid=B.Transid Left Join " + Branch_AliasName + ".Customers C On a.CustomerNumber=C.CustomerNumber Where (A.BusinessDate Between '" + D1 + "' And '" + D2 + "') And B.ItemStatus<>1 Group by Hour ORDER BY HOUR(a.TransTime);";
ReadResult = ObjMainCloud.GetData_DT(ChartQry);
DataTable DtFinaldata = new DataTable();
DataRow Dr = DtFinaldata.NewRow();
foreach (DataRow row in ReadResult.Rows)
{
RTimeGroupValue = row["TimeGroup"].ToString();
RAmount = row["Amount"].ToString();
if (DtFinaldata.Rows.Count > 0)
{
Dr["Tm"] = RTimeGroupValue;
Dr["Amount"] = RAmount;
DtFinaldata.Rows.Add(Dr);
DtFinaldata.AcceptChanges();
}
else
{
DtFinaldata.Columns.Add("Tm", typeof(string));
DtFinaldata.Columns.Add("Amount", typeof(decimal));
Dr["Tm"] = RTimeGroupValue;
Dr["Amount"] = RAmount;
}
DtFinaldata.Rows.Add(Dr);
DtFinaldata.AcceptChanges();
}
