- source IEnumerableT
- The sequence of items to fold.
- folder FuncT, T, T, T, TResult
- Function to apply to the elements in the sequence.
- T
- Type of element in the source sequence.
- TResult
- Type of the result.
TResultThe folded value returned by
folder.In Visual Basic and C#, you can call this method as an instance method on any object of type
IEnumerableT. 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).
This operator uses immediate execution and effectively buffers
as many items of the source sequence as necessary.
