推荐答案

在Framework 4中是非常简单的：

In Framework 4 it is really simple:

var s = string.Join(",", myArrayList);

在3.5与LINQ的扩展方法：

In 3.5 with LINQ's extension methods:

var s = string.Join(",", myArrayList.Cast<string>().ToArray());

这些都短，但不聪明了。

These are shorter but not smarter.

我不知道他们是如何应写入VB.NET。

I have no idea how they should be written with VB.NET.
