Exempel

Följande kodexempel visar hur du använder Zip metoden för att sammanfoga två sekvenser.

int[] numbers = { 1, 2, 3, 4 };
string[] words = { "one", "two", "three" };

var numbersAndWords = numbers.AsQueryable().Zip(words, (first, second) => first + " " + second);

foreach (var item in numbersAndWords)
    Console.WriteLine(item);

// This code produces the following output:

// 1 one
// 2 two
// 3 three

Dim numbers() As Integer = {1, 2, 3, 4}
Dim words() As String = {"one", "two", "three"}
Dim numbersAndWords = numbers.AsQueryable().Zip(words, Function(first, second) first & " " & second)

For Each item In numbersAndWords
    Console.WriteLine(item)
Next

' This code produces the following output:

' 1 one
' 2 two
' 3 three

Kommentarer

Metoden Zip genererar en MethodCallExpression som representerar att anropa Zip sig själv som en konstruerad generisk metod. Den skickar sedan till MethodCallExpression metoden för den CreateQuery<TElement>(Expression) som representeras av IQueryProvider egenskapen för parameternProvider.source1

Metoden sammanfogar varje element i den första sekvensen med ett element som har samma index i den andra sekvensen. Om sekvenserna inte har samma antal element sammanfogar metoden sekvenser tills den når slutet av ett av dem. Om en sekvens till exempel har tre element och den andra har fyra, har den resulterande sekvensen bara tre element.
