如何从我的 json 对象中删除不必要的 \\\'？

Question

I am trying to perform a simple convert operation on my string. The objective is to convert my string to json format.

string clientID= newClient.GetClientId();
string clientSecret = "ZDUyYTYyMjYtMTcyNC00ODkxLWI2NmMtMDlhZjA3MDdiOGQ2";
var stringObject= "{ clientID:"+ "'"+clientID+"', clientSecret:"+"'"+clientSecret+"'}" ;
var json= new JavaScriptSerializer().Serialize(stringObject);

However when i print the json ..The output shows something like this:

"{ clientID:\'YmY3NjZkM2ItZDg3MC00ZjQwLTk1NjktNTE0N2M1YzExOWMx\', clientSecret:\'ZDUyYTYyMjYtMTcyNC00ODkxLWI2NmMtMDlhZjA3MDdiOGQ2\'}\\"

How do i remove unnecessary \' ?

Answer 1

First step is to model a class that matches the JSON structure you need. In this case a class with 2 string properties will do:

public class FooType 
{
   public string clientID {get;set;}
   public string clientSecret {get;set;}
}

Next we need to instantiate this class and set its properties:

var foo = new FooType { 
    clientID = newClient.GetClientId(),
    clientSecret = "ZDUyYTYyMjYtMTcyNC00ODkxLWI2NmMtMDlhZjA3MDdiOGQ2",
};

then we can Serialize that into JSON:

var json= new JavaScriptSerializer().Serialize(foo);

The result in json will be:

{"clientID":"42","clientSecret":"ZDUyYTYyMjYtMTcyNC00ODkxLWI2NmMtMDlhZjA3MDdiOGQ2"}

Notice how the values are enclosed in double quotes, not in single ones and that no extra care is needed for escaping, removing or replacing chars. That is all handled by serializers because that is their main responsibility.

Although your code using the JavaScriptSerializer will still work, it is stated in the documentation that you better switch to Json.NET for serializing JSON. Your approach will be the same.

Using JObject from Newtonsoft.JSON.Linq will address the issue for someone trying to convert string directly..

   JObject json = JObject.Parse(str);

This is the sample code:

using System.Web;
using Newtonsoft.Json.Linq;

namespace MyTestProjectConsole
{
    public class Test1Json
    {
        public void ConvertJson()
       {
            string clientID = "aa";
            string clientSecret = "bb";
            var stringObject = "{ clientID:" + "'" + clientID + "', clientSecret:" + "'" + clientSecret + "'}";
            var json = JObject.Parse(stringObject);
            Console.WriteLine(json);
        }

        public static void Main()
        {
            Test1Json obj = new Test1Json();
            obj.ConvertJson();
            Console.ReadKey();
        }
    }
}

This generates the following output in console:

{
  "clientID": "aa",
  "clientSecret": "bb"
}

You can replace your json text string with this function that removes those characters:

var json= new JavaScriptSerializer().Serialize(stringObject);
json = System.Text.RegularExpressions.Regex.Unescape(json);
