How to append one DataTable to another DataTable

Question

I would like to append one DataTable to another DataTable. I see the DataTable class has two methods; \"Load(IDataReader)\" and \"Merge(DataTable)\". From the documentation

Answer 1

The datatype in the same columns name must be equals.

dataTable1.Merge(dataTable2);

After that the result is:

dataTable1 = dataTable1 + dataTable2
