Add an Array to a Dictionary in C#
提问by miltonjbradley
I have tried reading the other posts on this subject and can't quite figure this out.
我曾尝试阅读有关此主题的其他帖子，但无法弄清楚这一点。
I have a list in C# that I want to put in a dictionary with all of the same keys. The list is this
我在 C# 中有一个列表，我想将它放入具有所有相同键的字典中。清单是这个
string[] IN ={"Against","Like","Upon","Through","Of","With","Upon","On","Into","From","by","that","In","About","For"
,"Along","Before","Beneath","At","Across","beside","After","Though","Among","Toward","If"};
I want to create and populate a dictionary with the key being "IN" (the name of the array) and then having each string for the array in the dictionary.
我想创建并填充一个字典，键是“IN”（数组的名称），然后在字典中包含数组的每个字符串。
This is what I wrote to create the dictionary (which I am not sure is correct):
这是我为创建字典而写的内容（我不确定它是否正确）：
Dictionary<string, List<string>> wordDictionary = new Dictionary<string, List<string>> ()
But I am not sure how to populate the dictionary.
但我不确定如何填充字典。
Any help would be greatly appreciated as this is the first time I have tried to use a dictionary and I am new to C#
任何帮助将不胜感激，因为这是我第一次尝试使用字典，而且我是 C# 新手

An array is string[], not List<string>, so just do this:
一个数组是string[]，不是List<string>，所以只需这样做：
Dictionary<string, string[]> wordDictionary = new Dictionary<string, string[]>();
Now you can add your array as usual.
现在您可以像往常一样添加数组。
wordDictionary.Add("IN", IN);
Or:
或者：
wordDictionary.Add("IN", new string[] {"Against","Like","Upon","Through","Of","With","Upon","On","Into","From","by","that","In","About","For","Along","Before","Beneath","At","Across","beside","After","Though","Among","Toward","If"});

You currently have a string array, not a list - so it should be:
您目前有一个字符串数组，而不是列表 - 所以它应该是：
Dictionary<string, string[]> wordDictionary = new Dictionary<string,string[]> ()
Then you can just add items like:
然后您可以添加以下项目：
wordDictionary.Add("IN" , IN);
回答by Robert Harvey
Dictionary.Add("IN", new List<string>(IN));
...if you want to keep the current signature for your dictionary.
...如果您想保留字典的当前签名。
If you change it to Dictionary<string, string[]>then you can just:
如果你改变它，Dictionary<string, string[]>那么你可以：
Dictionary.Add("IN",IN);

Do you really need to convert your array into a string? You could very well use string[] instead of List in your dictionary:
您真的需要将数组转换为字符串吗？您可以在字典中使用 string[] 而不是 List ：
var wordDictionary = new Dictionary<string, string[]>();
wordDictionary.Add("IN", IN);
But if you really want to convert your string array to List:
但是，如果您真的想将字符串数组转换为 List：
var wordDictionary = new Dictionary<string, List<string>>();
wordDictionary.Add("IN", IN.ToList());

Another way to add the array (it's not a list) to the dictionary is to use collection initializer:
将数组（它不是列表）添加到字典的另一种方法是使用集合初始值设定项：
var wordDictionary = new Dictionary<string, string[]> { "IN", IN };
This is exactlythe same as creating the dictionary in a normal way and then calling Add("IN", IN).
这正好与在正常方式创建字典，然后调用Add("IN", IN)。
