Newtonsoft.Json.JsonConvert.DeserializeObject<T>() returns null-CodePudding

I want my json string data to be converted to an object.

Here is my json data

{
  "first_name": "Abdullah",
  "last_name": "Khan"
}

Here is my C# code:

string data = System.IO.File.ReadAllText(Server.MapPath(@"~/TextFiles/test.json"));
Test test = Newtonsoft.Json.JsonConvert.DeserializeObject<Test>(data);

Below is my getter setter class

public class Test 
{
    private string first_name { get; set; }
    private string last_name  { get; set; }
}

I have tried using the DeserializeObject() method but it does not put the value in the properties.

CodePudding user response：

declare the properties public like this

public class Test
{
    public string first_name { get; set; }
    public string last_name { get; set; }
}

also one small suggestion, please give the class a meaningful name like Student or Employee instead of Test.

CodePudding user response：

or just for a record, it will work with Newtonsoft.Json too, but it doesn't make much sense if your class doesn't have any another code

public class Test
{
    [JsonProperty("first_name")]
    private string first_name { get; set; }
    [JsonProperty("last_name")]
    private string last_name { get; set; }
}
