- source IEnumerableTSource
- The source sequence.
- comparer IEqualityComparerTSource
-
The equality comparer to use to determine whether one TSource
equals another. If , the default equality comparer for
TSource is used.
- TSource
- The type of the elements in the source sequence.
IEnumerableTSourceAll elements that are duplicated.In Visual Basic and C#, you can call this method as an instance method on any object of type
IEnumerableTSource. When you use instance method syntax to call this method, omit the first parameter. For more information, see
