Copying Data From a DataSet to another

Hey experts,

I need to make the RowState of all the rows of a certain DataSet "added", so I decided to add them one by one to a new DataSet, but apparently C# does not allow you to add to a new DataSet a row that already belongs to an existing one, I've tried tosolve this problem in more than 10 ways (by clearing the dataset, or putting the rows in an object array ...etc), but the problem remained the same........
The last way that I've tried to do it is as follows:

private DataSet RowInsertedDS(DataSet ds)
{
  DataSet ds2 = new DataSet();
  ds2 = ds.Clone();
  int count = ds.Tables[0].Rows.Count;
  ArrayList dr = new ArrayList();
  for(int i=0;i<count;i++)
  {
        dr.Add(ds.Tables[0].Rows[i]);
  }
  Object[] dr2 = new Object[count];
  dr.CopyTo(dr2);
  ds.Clear();
  ds.Dispose();
  dr.Clear();
  for(int i=0;i<dr2.Length;i++)
  {
           ds2.Tables[0].Rows.Add((DataRow)dr2[i]);
  }
  return ds2;
}

The problem still occured (in the code above) in the before last line of code (inside the last for loop)....any help on solving the problem??

Look at the DataTable.ImportRow method instead.

The method copied the rows msuccessfully into the new dataset, but the STATE of the rows remained unchanged (and not  inserted).

Problem Solved:

When setting the property AcceptChangesDuringFill to false in SqlDataAdapter, the state of the rows when filling a dataset becomes added (and not unchanged)....
