Determines if the list contains any item that compares equal to item. The implementation simply checks whether IndexOf(item) returns a non-negative value.

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

Syntax

C#
public override bool Contains( T item )

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

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

Parameters

item: T
The item to search for.

Return Value

True if the list contains an item that compares equal to item.

Remarks

Equality in the list is determined by the default sense of equality for T. If T implements IComparable<T>, the Equals method of that interface is used to determine equality. Otherwise, Object.Equals is used to determine equality.
