EquiZipExtensionEquiZipTFirst, TSecond, TResult(IEnumerableTFirst, IEnumerableTSecond, FuncTFirst, TSecond, TResult) Method

Returns a projection of tuples, where each tuple contains the N-th element from each of the argument sequences. An exception is thrown if the input sequences are of different lengths.

	this IEnumerable<TFirst> first,
	IEnumerable<TSecond> second,
	Func<TFirst, TSecond, TResult> resultSelector
)

<ExtensionAttribute>
Public Shared Function EquiZip(Of TFirst, TSecond, TResult) ( 
	first As IEnumerable(Of TFirst),
	second As IEnumerable(Of TSecond),
	resultSelector As Func(Of TFirst, TSecond, TResult)
) As IEnumerable(Of TResult)

C++

public:
[ExtensionAttribute]
generic<typename TFirst, typename TSecond, typename TResult>
static IEnumerable<TResult>^ EquiZip(
	IEnumerable<TFirst>^ first, 
	IEnumerable<TSecond>^ second, 
	Func<TFirst, TSecond, TResult>^ resultSelector

F#

[<ExtensionAttribute>]
static member EquiZip : 
        first : IEnumerable<'TFirst> * 
        second : IEnumerable<'TSecond> * 
        resultSelector : Func<'TFirst, 'TSecond, 'TResult> -> IEnumerable<'TResult>

Parameters

first IEnumerableTFirst: The first sequence.
second IEnumerableTSecond: The second sequence.
resultSelector FuncTFirst, TSecond, TResult: Function to apply to each pair of elements.

Type Parameters

TFirst: Type of elements in first sequence.
TSecond: Type of elements in second sequence.
TResult: Type of elements in result sequence.

Return Value

IEnumerableTResult
A sequence that contains elements of the two input sequences, combined by resultSelector.

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).

Remarks

This operator uses deferred execution and streams its results.

Example

C#

var numbers = new[] { 1, 2, 3, 4 };
var letters = new[] { "A", "B", "C", "D" };
var zipped  = numbers.EquiZip(letters, (n, l) => n + l);

The zipped variable, when iterated over, will yield "1A", "2B", "3C", "4D" in turn.

Exceptions

InvalidOperationException	The input sequences are of different lengths.
ArgumentNullException	first, second, or resultSelector is .
