我正在使用看起来像这样的第三方来使用JSON：
{"id":"1","[question(21), option(\"10033-other\")]":"","[question(22)]":"electric"}
我理解当键名是一个简单的字符串时如何获取值。但是当键名不是基本字符串时，我无法弄清楚如何获取值。我如何反序化[问题（21）]和[问题（22）]值？
我的代码如下。
类：
public class MyFeed
{
public string id { get; set; }
}
public class MyFeedClass
{
public List<MyFeed> data { get; set; }
}
Program.cs的
static void Main(string[] args)
{
string webReq = String.Empty;
webReq += "https://restapi.surveygizmo.com/head/survey/zzzzzzzzz";
webReq += "/surveyresponse/";
webReq += "?user:pass=xxxxxx:yyyyyyyyy";
HttpWebRequest request = WebRequest.Create(webReq) as HttpWebRequest;
var myString = String.Empty;
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
StreamReader reader = new StreamReader(response.GetResponseStream());
myString += reader.ReadToEnd();
}
MyFeedClass myFeedClass =
new JavaScriptSerializer().
Deserialize<MyFeedClass>(myString);
Console.Title = "Bentley - Survey Data Loader";
Console.WriteLine("");
foreach (var item in myFeedClass.data)
{
Console.WriteLine("id: {0}", item.id);
}
Console.WriteLine("");
Console.WriteLine("Press enter to exit...");
Console.ReadLine();
}

您的JSON和您的课程看起来不匹配 - 也就是说，通过一些调整，您可以获得某些来反序列化它：
如果我们将您发布的JSON包装成如此：
string data = @"{""data"":{""id"":""1"",""[question(21), option(\""10033-other\"")]"":"""",""[question(22)]"":""electric""}}";
（或以非破损形式）
{"data":{"id":"1","[question(21), option(\"10033-other\")]":"","[question(22)]":"electric"}}
然后重新定义了饲料类：
public class MyFeedClass
{
public Dictionary<string,string> data { get; set; }
}
new JavaScriptSerializer().Deserialize<MyFeedClass>(data)
制作包含内容的Dictionary<string,string>：
{id, 1 }
{[question(21), option("10033-other")], }
{[question(22)], electric }
