	folder As Func(Of T, T, T, TResult)
) As TResult

[ExtensionAttribute]
generic<typename T, typename TResult>
static TResult Fold(
	IEnumerable<T>^ source, 
	Func<T, T, T, TResult>^ folder
)

[<ExtensionAttribute>]
static member Fold : 
        source : IEnumerable<'T> * 
        folder : Func<'T, 'T, 'T, 'TResult> -> 'TResult

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).

Remarks

This operator uses immediate execution and effectively buffers as many items of the source sequence as necessary.
