How to convert a JToken

You should use:

int totalDatas = tData.Value<Int32>();

You can use the JToken.ToObject<T>() method.

JToken token = ...;
int value = token.ToObject<int>();

try this: int value = (int)token.Value;

You can simply cast the JToken to int :

string json = @"{totalDatas : ""1234""}";
JObject obj = JObject.Parse(json);
JToken token = obj["totalDatas"];
int result = (int)token;

//print 2468
Console.WriteLine(result*2);
