百分请教!如何能够得到一个Collection中每一个Item的Key?
Dim colList as new Collection
collist.add AAA , a
collist.add BBB , b
collist.add CCC , c
collist.add DDD , d

很奇怪,调试的时候查看colList这个对象,在对象查看器中可以看到colList里面Item的Key值,但是却没有办法在程序中取得?

请教高手,应该如何才能得到Key?

这样不可以吗?
for(int i=0;i
{
Response.Write(Collection.Items[i].Value);
}
__________________________________________________________________________
Collection.Items[i].key可以啊
__________________________________________________________________________
for(int i=0;i
{
Response.Write(Collection.Items[i].key);
}

谢谢楼上各位的帮忙.
我刚试了一下。好像Collection.Item(i).key根本就无法访问（VB.NET中）,难道C#中可以使用Collection.Items[i].key访问吗?

不过我对C#不熟，请问C#中如何声明一个Collection对象？

vb.net中Collection的对象的key值是没办法取的。

我也试过，没能取出Collection中对象的key值！

应该使用Hashtable:

Dim colList as new Hashtable
collist.add( AAA , a )
collist.add( BBB , b )
collist.add( CCC , c )
collist.add( DDD , d )

Dim ide As IDictionaryEnumerator
While ie.MoveNext()
Console.WriteLine(ie.Key);
End Whild
__________________________________________________________________________
ide = colList.GetEnumerator
__________________________________________________________________________
手写的,有错!修正:

Dim ide As IDictionaryEnumerator = colList.GetEnumerator()
While ide.MoveNext()
Console.WriteLine(ide.Key);
End Whild
__________________________________________________________________________
可以直接利用key
Dim colList as new Collection
collist.add AAA , a
collist.add BBB , b
collist.add CCC , c
collist.add DDD , d

Dim test as string
test = colList( a ).ToString()

那么test = AAA

要是非得要KEY 可以写个结构体定义一个key

基本明白了!谢谢楼上各位!
