DataColumnCollection.Remove Method (DataColumn)
Removes the specified DataColumn object from the collection.
Assembly: System.Data (in System.Data.dll)
If the collection is successfully changed by adding or removing columns, the CollectionChanged event occurs.
The following example uses the Contains method to determine whether a named column exists. If so, the Item property returns the column. The CanRemove method then checks whether the column can be removed; if so, the Remove method removes it.
