C#如何取出字符串里面指定的值呢？

Question

这是我要取的字符串

string source2 = @"{""c"":""run"",""x"":"100"",""y"":""20"",""z"":""0"",""r"":""0"",""v"":""322""}";

我想取x，y，z，r后面的四个值100，20，0，0

要如何取呢？本来想用split，可是也不太行，求指教！

Answer 1

两个办法，一个是用正则匹配，一个是用Newtonsoft第三方json库将这个转成json然后读取

另外，你的这个字符串赋值好像也有问题

string source2 = @"{""c"":""run"",""x"":"**"**100"",""y"":""20"",""z"":""0"",""r"":""0"",""v"":""322""}";

100前少了个双引号

            string source2 = @"{""c"":""run"",""x"":""100"",""y"":""20"",""z"":""0"",""r"":""0"",""v"":""322""}";
            string x = Regex.Match(source2, @"(?<=""x"":"")\d+").Value;
            string y = Regex.Match(source2, @"(?<=""y"":"")\d+").Value;
            string z = Regex.Match(source2, @"(?<=""z"":"")\d+").Value;
            string r = Regex.Match(source2, @"(?<=""r"":"")\d+").Value;
            Hashtable ht = JsonConvert.DeserializeObject<Hashtable>(source2);
            string x1 = ht["x"].ToString();
            string y1 = ht["y"].ToString();
            string z1 = ht["z"].ToString();
            string r1 = ht["r"].ToString();
