Convert JSON response stream to string
提问by Tom
I am trying to do a POST and then read the JSON response into a string.
我正在尝试执行 POST，然后将 JSON 响应读入字符串。
I believe my issue is that I need to pass my own object into DataContractJsonSerializer but I'm wondering if there is some way to just get the response into an associative array or some sort of key/value format.
我相信我的问题是我需要将我自己的对象传递给 DataContractJsonSerializer 但我想知道是否有某种方法可以将响应放入关联数组或某种键/值格式。
My JSON is formatted like: {"license":"AAAA-AAAA-AAAA-AAAA"} and my code is as follows:
我的 JSON 格式如下：{"license":"AAAA-AAAA-AAAA-AAAA"} 我的代码如下：
using (Stream response = HttpCommands.GetResponseStream(URL, FormatRegistrationPost(name, email)))
{
string output = new StreamReader(response).ReadToEnd();
response.Close();
DataContractJsonSerializer json = new DataContractJsonSerializer(typeof(string));
MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(output));
string results = json.ReadObject(ms) as string;
licenseKey = (string) results.GetType().GetProperty("license").GetValue(results, null);
}

I'd strongly recommend looking into Newtonsoft.Json:
我强烈建议您查看 Newtonsoft.Json：
http://james.newtonking.com/pages/json-net.aspx
http://james.newtonking.com/pages/json-net.aspx
NuGet: https://www.nuget.org/packages/newtonsoft.json/
NuGet：https: //www.nuget.org/packages/newtonsoft.json/
After adding the reference to your project, you just include the following usingat the top of your file:
添加对项目的引用后，您只需using在文件顶部包含以下内容：
using Newtonsoft.Json.Linq;
And then within your method you can use:
然后在您的方法中，您可以使用：
var request= (HttpWebRequest)WebRequest.Create("www.example.com/ex.json");
var response = (HttpWebResponse)request.GetResponse();
var rawJson = new StreamReader(response.GetResponseStream()).ReadToEnd();
var json = JObject.Parse(rawJson); //Turns your raw string into a key value lookup
string license_value = json["license"].ToObject<string>();

you can do something like this using dictionary
你可以使用字典做这样的事情
Dictionary<string, string> values =
JsonConvert.DeserializeObject<Dictionary<string, string>>(json);
or something like this if you already know your object
或者类似的东西，如果你已经知道你的对象
var yourobject = JsonConvert.DeserializeObject<YourObject>(json);
with this tool
用这个工具
