DataColumnCollection.Add Method (String, Type)
Assembly: System.Data (in System.Data.dll)
If a null reference (Nothing in Visual Basic) or an empty string ("") is passed in for the name, a default name ("Column1", "Column2", and so on) is given to the column.
Use the Contains method to determine whether a column with the proposed name already exists in the collection.
If the collection is successfully changed by adding or removing columns, the CollectionChanged event occurs.
