Checks whether the collection contains a column with the specified name.

Namespace:   System.Data
Assembly:  System.Data (in System.Data.dll)

public:
bool Contains(
	String^ name
)

Parameters

name
Type: System::String^

The ColumnName of the column to look for.

Return Value

Type: System::Boolean

true if a column exists with this name; otherwise, false.

Use the Contains 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 Contains method and the CanRemove method to determine whether the column can be removed. If so, the column is removed.
