Hashtable无序,用Dictionary代替

//输出1234
public void TestDictionary()
{
Dictionary<string, int> dic = new Dictionary<string, int>();
dic.Add("One", 1);
dic.Add("Two", 2);
dic.Add("Three", 3);
dic.Add("Four", 4);

foreach (var r in dic.Keys)
{
Response.Write(dic[r]);
}
}

//输出2341
public void TestHashtable()
{
Hashtable ht = new Hashtable();
ht.Add("One", 1);
ht.Add("Two", 2);
ht.Add("Three", 3);
ht.Add("Four", 4);

foreach (var r in ht.Keys)
{
Response.Write(ht[r]);
}
}
