Checks whether the collection contains a column with the specified name.
Assembly: System.Data (in System.Data.dll)
Use the method to confirm the existence of a column before you perform additional operations on the column. The method returns false when two or more columns have the same name but different namespaces. The call does not succeed if there is any ambiguity when matching a column name to exactly one column.
The following example uses the method and the CanRemove method to determine whether the column can be removed. If so, the column is removed.
