<p>In Python there is a really neat function called <code>zip</code> which can be used to iterate through two lists at the same time:</p>

<pre><code>list1 = [1, 2, 3]
list2 = ["a", "b", "c"]
for v1, v2 in zip(list1, list2):
    print v1 + " " + v2
</code></pre>

<p>The above code should produce the following:</p>

<pre>1 a
2 b
3 c</pre>

<p>I wonder if there is a method like it available in .Net? I'm thinking about writing it myself, but there is no point if it's already available.</p>

Nope, there is no such function in .NET. You have roll out your own. Note that C# doesn't support tuples, so python-like syntax sugar is missing too.
You can use something like this:
```
```
class Pair<T1, T2>
{
    public T1 First { get; set;}
    public T2 Second { get; set;}
}

static IEnumerable<Pair<T1, T2>> Zip<T1, T2>(IEnumerable<T1> first, IEnumerable<T2> second)
{
    if (first.Count() != second.Count())
        throw new ArgumentException("Blah blah");

    using (IEnumerator<T1> e1 = first.GetEnumerator())
    using (IEnumerator<T2> e2 = second.GetEnumerator())
    {
        while (e1.MoveNext() && e2.MoveNext())
        {
            yield return new Pair<T1, T2>() {First = e1.Current, Second = e2.Current};
        }
    }
}

...

var ints = new int[] {1, 2, 3};
var strings = new string[] {"A", "B", "C"};

foreach (var pair in Zip(ints, strings))
{
    Console.WriteLine(pair.First + ":" + pair.Second);
}
```
```
