戻り値

2 つの入力シーケンスのマージされた要素を含む IQueryable<T> 。

例外

例

次のコード例では、 Zip メソッドを使用して 2 つのシーケンスをマージする方法を示します。

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

注釈

Zip メソッドは、構築されたジェネリック メソッドとしての呼び出しZip自体を表すMethodCallExpressionを生成します。 次に、source1 パラメーターのProvider プロパティで表されるIQueryProviderのCreateQuery<TElement>(Expression) メソッドにMethodCallExpressionを渡します。

このメソッドは、最初のシーケンスの各要素を、2 番目のシーケンスで同じインデックスを持つ要素とマージします。 シーケンスが同じ数の要素を持たない場合、メソッドはいずれかの要素の末尾に達するまでシーケンスをマージします。 たとえば、1 つのシーケンスに 3 つの要素があり、もう 1 つのシーケンスに 4 つの要素がある場合、結果のシーケンスには 3 つの要素のみが含まれます。
