Determines if the collection contains a particular item. This default implementation iterates all of the items in the collection via GetEnumerator, testing each item against item using IComparable<T>.Equals or Object.Equals.

Namespace: Wintellect.PowerCollections
Assembly: PowerCollections (in PowerCollections.dll)

Syntax

C#
public virtual bool Contains( T item )

Visual Basic (Declaration)
Public Overridable Function Contains ( _ item As T _ ) As Boolean

Visual C++
public: virtual bool Contains ( T item )

Parameters

item: T
The item to check for in the collection.

Return Value

True if the collection contains item, false otherwise.

Remarks

You should strongly consider overriding this method to provide a more efficient implementation, or if the default equality comparison is inappropriate.
