Zip<TFirst,TSecond,TResult>(IEnumerable<TFirst>, IEnumerable<TSecond>, Func<TFirst,TSecond,TResult>)
将指定函数应用于两个序列的对应元素,以生成结果序列。
Zip<TFirst,TSecond,TThird>(IEnumerable<TFirst>, IEnumerable<TSecond>, IEnumerable<TThird>)
使用三个指定序列中的元素生成元组序列。

string[] words = { "one", "two", "three" };
var numbersAndWords = numbers.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.Zip(words, Function(first, second) first & " " & second)
For Each item In numbersAndWords
Console.WriteLine(item)
' This code produces the following output:
' 1 one
' 2 two
' 3 three
此方法通过使用延迟执行来实现。 即时返回值是一个对象,用于存储执行操作所需的所有信息。 在通过直接调用
GetEnumerator
其方法或在 C#
For Each
或
foreach
Visual Basic 中使用 来枚举对象之前,不会执行此方法表示的查询。
方法将第一个序列的每个元素与在第二个序列中具有相同索引的元素合并。 如果序列的元素数不同,则 方法会合并序列,直到到达其中一个序列的末尾。 例如,如果一个序列有三个元素,另一个序列有四个元素,则结果序列将只有三个元素。
