如何反序列化字典并获取特定键的值

Question

How should I get the value of status key?

string a = "\"[{\\\"Status\\\":\\\"Passed\\\"}]\""

tried with JObject.Parse and JArray.Parse to deserialize it and fetch the value. getting error all the time, even if the key is present.

PS: this value is coming directly from the DB, where it is stored as a string.

Answer 1

Maybe there is a better solution. But you can remove the / character and split by "

string a = "\"[{\\\"Status\\\":\\\"Passed\\\"}]\"";
var val=a.Replace("\\", "").Split(new string[] { "\"" },
StringSplitOptions.None)[4];

Answer 2

using System.Text.Json;

string a = "\"[{\\\"Status\\\":\\\"Passed\\\"}]\"";
var json = JsonDocument.Parse(a).RootElement.GetString();
var jDoc = JsonDocument.Parse(json);
var dic = jDoc.RootElement[0].Deserialize<Dictionary<string, string>>();
var status = dic["Status"];

Answer 3

Here is a method can get the value, hope it can give you some help.

using Newtonsoft.Json;

string a = "\"[{\\\"Status\\\":\\\"Passed\\\"}]\"";
var b = JsonConvert.DeserializeObject(a);
var c = JsonConvert.DeserializeObject<Dictionary<string, string>[]>(b.ToString());
