如何在C#中使用Python的zip？

Question

Python的zip功能执行以下操作:

a = [1, 2, 3]
b = [6, 7, 8]
zipped = zip(a, b)

结果

[[1, 6], [2, 7], [3, 8]]

Answer 1

怎么样这个？

C#4.0 LINQ的新ZIP操作员

public static IEnumerable<TResult> Zip<TFirst, TSecond, TResult>(
        this IEnumerable<TFirst> first,
        IEnumerable<TSecond> second,
        Func<TFirst, TSecond, TResult> func);

Answer 2

解决方案2:与C#4.0 Zip类似,但您可以在C#3.0中使用它

    public static IEnumerable<TResult> Zip<TFirst, TSecond, TResult>(
        this IEnumerable<TFirst> first,
        IEnumerable<TSecond> second,
        Func<TFirst, TSecond, TResult> func)
    {
        using(var enumeratorA = first.GetEnumerator())
        using(var enumeratorB = second.GetEnumerator())
        {
            while (enumeratorA.MoveNext())
            {
                enumeratorB.MoveNext();
                yield return func(enumeratorA.Current, enumeratorB.Current);
            }
        }
    }
