) As Integer

static int CompareCount(
	IEnumerable<TFirst>^ first, 
	IEnumerable<TSecond>^ second
)

[<ExtensionAttribute>]

        first : IEnumerable<'TFirst> * 
        second : IEnumerable<'TSecond> -> int

Parameters

first: Type: System.Collections.Generic.IEnumerable<TFirst>
The first sequence
second: Type: System.Collections.Generic.IEnumerable<TSecond>
The second sequence

-1 if the first sequence has the fewest elements, 0 if the two sequences have the same number of elements or 1 if the first sequence has the most elements.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable<TFirst>. 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).
