Determines whether the Hashtable contains a specific value.
Assembly: mscorlib (in mscorlib.dll)
abstract ContainsValue : value:Object -> bool override ContainsValue : value:Object -> bool
This method performs a linear search; therefore, this method is an O(n) operation, where n is Count.
Starting with the .NET Framework 2.0, this method uses the collection’s objects’ Equals and CompareTo methods on item to determine whether item exists. In the earlier versions of the .NET Framework, this determination was made by using the Equals and CompareTo methods of the item parameter on the objects in the collection.

The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
