Hi all,
I have a dictionary like this:
Dictionary<List<string>, List<string>>
How can I iterate in it?
Thanks very much.

推荐答案
那么，你想要迭代什么？每个键（一个List< string>）可能有多个
多个valies - 你只想要这些值吗？
使用C＃3.0 / .NET 3.5，SelectMany是一个选项，但我想（最后发表）
这不是一个选择。所以你只需要几个嵌套的foreach循环。

Well, what do you want to iterate? Each key (a List<string>) could have
multiple valies - do you just want the values?
With C# 3.0 / .NET 3.5, SelectMany is an option, but I guess (last post)
that this isn''t an option. So you''ll just need a few nested foreach loops.

是的，我正在使用C＃2.0，因此禁止使用许多有用的选项。
我想要的是获取我字典中
第一个列表的每个字符串的字符串集合。

Yes, I''m using C# 2.0, so many useful options are prohibited for me.
What I''d like is to obtain the collection of strings for every string of the
first List in my dictionary.

你能举一个简单的例子吗？
ie
" if数据有点膨胀，然后我想{你的位在这里}
第1项：键（列表）" a"，" b"
值（列表）c，d，e
项目2：密钥（列表）" f"
value（list）" g"，" h"
Marc
Can you show that with a simple example?
i.e.
"if the data was as bloe, then I want {your bit here}
item 1: key (list) "a", "b"
value (list) "c", "d", "e"
item 2: key (list) "f"
value (list) "g", "h"
