如下的代码内容是关于在C#中使用foreach遍历hashtable哈希表的代码，应该是对小伙伴们也有好处。

using System;using System.Collection;namespace HashSampleApplication1{ class Program { static void Main() { Hashtable hash = new Hashtable(); hashtable[1] = "kaka"; hashtable[2] = "biryani"; hashtable[13] = "kadai"; foreach (string key in hash.Keys) { Console.WriteLine(key + ‘=’ + hash[key]); } } }}
