Ejemplos

En el ejemplo de código siguiente se muestra cómo usar el Zip método para combinar dos secuencias.

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

Comentarios

El Zip método genera un MethodCallExpression objeto que representa llamarse Zip a sí mismo como un método genérico construido. A continuación, pasa al MethodCallExpressionCreateQuery<TElement>(Expression) método del IQueryProvider representado por la Provider propiedad del source1 parámetro .

El método combina cada elemento de la primera secuencia con un elemento que tiene el mismo índice en la segunda secuencia. Si las secuencias no tienen el mismo número de elementos, el método combina secuencias hasta que llega al final de una de ellas. Por ejemplo, si una secuencia tiene tres elementos y la otra tiene cuatro, la secuencia resultante tendrá solo tres elementos.
