Hastable的两种遍历方式

今天简单的看了下hashtable，发现用两种方式都可以遍历

 

代码

Hashtable ht = new Hashtable();
ht.Add("1", "America");
ht.Add("2", "China");
ht.Add("3", "Japan");


IDictionaryEnumerator myEnumerator = ht.GetEnumerator();
while (myEnumerator.MoveNext())
{
Console.WriteLine(myEnumerator.Key.ToString());
Console.WriteLine( myEnumerator.Value.ToString());
}

if(ht.Contains("3"))
{
ht.Remove("3");
}

foreach(DictionaryEntry de in ht)
{
Console.WriteLine(de.Key.ToString());
Console.WriteLine(de.Value.ToString());

}

Console.ReadLine();
