System.Collections.IList.Contains Method

Determines whether the IList contains a specific value.

Syntax

public bool Contains (object value)

Parameters

value
The object to locate in the IList.

Returns

true if the object is found in the IList; otherwise, false.

Remarks

Starting with the .NET Framework 2.0, this method uses the collection’s objects’ object.Equals(object) and IComparable.CompareTo(object) methods on item to determine whether item exists. In the earlier versions of the .NET Framework, this determination was made by using the object.Equals(object) and IComparable.CompareTo(object) methods of the item parameter on the objects in the collection.
