You need to use "importrow" when only you have rows to be copied, without merging the new structure.

simply:

For index = 0 To dtOld.Rows.Count - 1
dtNew.ImportRow(dtReceived.Rows(index))
Next

try like this..

C#

 dtValidData = dsbmVillagedata.Tables[0].Clone(); // place this line outside the loop.

foreach (DataRow dr in dsbmVillagedata.Tables[0].Rows)
                         {
 dtValidData = dsbmVillagedata.Tables[0].Clone();
                                DataRow drNew=dtValidData.NewRow();
                                drNew.ItemArray =dr.ItemArray;
                                dtValidData.Rows.Add(drNew);
                                int a = dtValidData.Rows.Count;
}
