Queue.Contains Method (Object)
Determines whether an element is in the Queue.
Assembly: mscorlib (in mscorlib.dll)
This method determines equality by calling Object.Equals.
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 obj 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 obj parameter on the objects in the collection.
