	IEnumerable<TSecond> second
)

<ExtensionAttribute>

	first As IEnumerable(Of TFirst),
	second As IEnumerable(Of TSecond)
) As Integer

public:
[ExtensionAttribute]
generic<typename TFirst, typename TSecond>
static int CompareCount(
	IEnumerable<TFirst>^ first, 
	IEnumerable<TSecond>^ second
)

[<ExtensionAttribute>]
static member CompareCount : 
        first : IEnumerable<'TFirst> * 
        second : IEnumerable<'TSecond> -> int

Parameters

first: Type: System.Collections.GenericIEnumerableTFirst
The first sequence
second: Type: System.Collections.GenericIEnumerableTSecond
The second sequence

Type Parameters

TFirst: Element type of the first sequence
TSecond: Element type of the second sequence

Type: Int32
-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 IEnumerableTFirst. 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).
