C＃split，返回数组中的键/值对

I'm new to C#, and thus am looking for layman's terms regarding this. Essentially, what I would like to do is turn:

我是C＃的新手，因此我正在寻找外行人的条款。基本上，我想做的是转：

key1=val1|key2=val2|...|keyN=valN

键1 = VAL1 |键2 =值2 | ... | keyN = VALN

into a database array where, you guessed it, key1 returns val1, key2 returns val2, etc. I know I could return a string using split, but from that point on, I'm at a loss. Any help would be greatly appreciated! I hope I've made my intentions clear, but if you have any questions, don't hesitate to ask!

进入一个数据库数组，你猜对了，key1返回val1，key2返回val2等等。我知道我可以使用split返回一个字符串，但从那时起，我不知所措。任何帮助将不胜感激！我希望我的意图明确，但如果您有任何疑问，请不要犹豫！

3 个解决方案

#1

string s = "key1=val1|key2=val2|keyN=valN";
var dict = s.Split('|')
            .Select(x => x.Split('='))
            .ToDictionary(x => x[0], x => x[1]);

Now dict is a Dictionary<string, string> with the desired key/value pairs.

现在dict是一个Dictionary ，带有所需的键/值对。，string>

#2

Dictionary<string,string> results = new Dictionary<string,string>();
foreach(string kvp in source.split('|'))
{
    results.Add(kvp.split('=')[0], kvp.split('=')[1]);
}

Probably a Linq way of doing it.

可能是Linq这样做的方式。

#3

 string s = "key1=val1|key2=val2|keyN=valN";
 var dict = s.Split('|')
 .Select(x => x.Split('='))
 .Where(x => x.Length > 1 && !String.IsNullOrEmpty(x[0].Trim())
  && !String.IsNullOrEmpty(x[1].Trim()))
 .ToDictionary(x => x[0].Trim(), x => x[1].Trim());

#1

string s = "key1=val1|key2=val2|keyN=valN";
var dict = s.Split('|')
            .Select(x => x.Split('='))
            .ToDictionary(x => x[0], x => x[1]);
