Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).


Removal is supported if collection is either an IList or ICollectionT implementation.


If it is known that the collection implements only the supported generic ICollectionT interface, then for better performance use the generic TryRemove<T> overload if possible.
