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.
