How to convert it to object and post it to api. I have already know how to post but I need to post user object with parameters. I tried this:

JObject jobjects = new JObject();
JObject jobjectss = new JObject();
jobjects["user"] = jobjectss;
jobjectss["id"] = 121;
jobjectss["username"] = "luckygirlx3";
jobjectss["counter_rechecking"] = 0;
jobjectss["user_id"] = 76;
jobjectss["f_Id"] = "4334";

How to Convert Json to object c# To Post Data APi

This seems like you want to convert a JSON response to a object. If this is the case then you want to deserialize your JSON. You havn't posted your Post Data code, so I can't help much with that.

I would first map your JSON to classes:

public class User
{
    public int Id { get; set; }
    public string Username { get; set; }
    [JsonProperty("counter_rechecking")]
    public int CounterRechecking { get; set; }
    [JsonProperty("user_id")]
    public int UserId { get; set; }
    [JsonProperty("f_id")]
    public string FId { get; set; }
}

public class RootObject
{
    public User User { get; set; }
}

Then deserialize your JSON to RootObject with Json.NET :

var deserializedJson = JsonConvert.DeserializeObject<RootObject>(json);

You can then access your properties like this:

Console.WriteLine(deserializedJson.User.Id);
Console.WriteLine(deserializedJson.User.Username);
Console.WriteLine(deserializedJson.User.CounterRechecking);
Console.WriteLine(deserializedJson.User.UserId);
Console.WriteLine(deserializedJson.User.FId);

I used JsonProperty to map your attributes with _ to nicer property members. This is optional however.

You can also use something like json2csharp.com or Edit -> Paste Sepcial -> Paste JSON as classes inside Visual Studio after copying your JSON to the clipboard to generate the classes for you.
