How can I get the key of a dictionary by passing the index value?

如何通过传递索引值来获取字典的键？

I'm trying:

我想：

If rs.Fields("NM").Value = dictNM.key(0)

that is, I want it to compare to the first key in the dictionary

也就是说，我希望它与字典中的第一个键进行比较

but I get the error

但我得到了错误

Compile error: Invalid use of property

I tried googling, but to no avail. I'm hoping this is even possible.

我尝试谷歌搜索，但无济于事。我希望这甚至是可能的。

You should be able to use the Keys property:

您应该能够使用 Keys 属性：

dictNM.Keys(0)

Edit:
One thing to keep in mind is that the order of the keys is unspecified, see MSDN

编辑：
要记住的一件事是未指定键的顺序，请参阅MSDN

Dictionary.ElementAt(index) works for me. It returns the Key/Value pair at the specified index.

Dictionary.ElementAt(index) 对我有用。它返回指定索引处的键/值对。
