这段代码给出了带有json标签的空json字符串，请为此提供帮助 [英] This code is giving null json string with json tags please help for this

问题描述

string json = new WebClient().DownloadString(" http://[doaminName]/rpsconline/rest/kioskWebService/getApplicationStatus?dob=" + dob + "&token_transaction_no=" + mobileno);

string[] s1 = new string[] { "application_id", "candidateName", "dob", "fatherName", "mobileNo", "responseError", "responseStatus", "[", "{", "\"", ":", ".", ",", "}", "]" };
string[] strSplitArr = json.Split(s1, StringSplitOptions.RemoveEmptyEntries);

我在json变量中遇到问题，它给出了空值。

I am getting problem in json variable, it is giving null values.

推荐答案

你的尝试解决方案并解析答案（这是json）作为字符串你自己是一个坏的...

声明具有答案结构的类：

Your solution to try and parse the answer (which is json) as string by yourself is a bad one...
Declare class with the structure of the answer:

public class Result
{
  public string ApplicationID;
  public string CandidateName;
  // so on
}

然后使用 Json.NET [ ^ ]为你解析它...

Then use Json.NET[^] to parse it for you...

Result res = JsonConvert.DeserializeObject<Result[]>(json);

您应该使用数组类型，因为JSON正在返回一个数组。

You should use array type as JSON is returning an array.

Result res = JsonConvert.DeserializeObject<Result[]>(json);

另外你应该正确地遵循错误信息，你可能会提供错误的查询字符串值和有效密钥。



那是：Key：

Another thing you should follow the error message properly it may be case of you are provide wrong query string value with valid key.

That's is : Key :

token_transaction_no

但值是：MobileNo

but Value is : MobileNo
