copy data from one datatable to another - different schemas

[mcnewsxp]

how can i copy data from one datatable to another when the schemas are not the same. i do not need to clone. the table structures are the same, but the data i need to copy over doesn't contain a header row so the first row ends up being the header. so i need to get a header row in there then copythe data over.
tia,

DataRow newPlateRow = ds.Tables[0].NewRow();
for (int i = 0; i < dataSet.Tables[0].Rows.Count; i++)
{
newPlateRow = ds.Tables[0].NewRow();
newPlateRow[0] = dataSet.Tables[0].Rows.ItemArray[0].ToString();
newPlateRow[1] = dataSet.Tables[0].Rows.ItemArray[1].ToString();
ds.Tables[0].Rows.Add(newPlateRow);
}

DataRow newPlateRow = ds.Tables[0].NewRow();

You create an object that you do not use.

for (int i = 0; i < dataSet.Tables[0].Rows.Count; i++)
{
newPlateRow = ds.Tables[0].NewRow();
newPlateRow[0] = dataSet.Tables[0].Rows.ItemArray[0].ToString();
newPlateRow[1] = dataSet.Tables[0].Rows.ItemArray[1].ToString();

Why are you calling ToString()?

ds.Tables[0].Rows.Add(newPlateRow);
}
