    When you are debugging a program, then type s,nq into Watch window or Immediate window, where s is your variable.

    The \" is required to specify a " inside the string; the \ is not actually present is the string.

    Hi,

    {\"id\":1,\"value\":\"max\"} is the minimal string expression of {"id":1,"value":"max"} . So you couldn't remove .

    System.Text.Json.JsonSerializer.Serialize is used to convert object to a json string. But {\"id\":1,\"value\":\"max\"} is already a json string format, so there's no point to convert.

    Instead, {\"id\":1,\"value\":\"max\"} can be used to deserialized(convert from json string to object). JsonConvert (from package Newtonsoft.Json)is better for use because it doesn't need class information when deserialize.

    Another thing you may want to do is convert a jsonString to jsonObject, it will be easier to read values.

    You can try the following code.

    string a = "{\"id\":1,\"value\":\"max\"}";
    var b = JsonConvert.SerializeObject(a);
    var c = JsonConvert.DeserializeObject(a);
    var d = JsonObject.Parse(a);
    Console.WriteLine("orginial string:" + a);
    Console.WriteLine("Serialize:"+ b);
    Console.WriteLine("Deserialize:" + c);
    Console.WriteLine("value:"+d["value"]);
    

    Output
