How to convert a JToken

问题

I have a JToken with the value {1234}

How can I convert this to an Integer value as var totalDatas = 1234;

var tData = jObject["$totalDatas"];
int totalDatas = 0;
if (tData != null)
   totalDatas = Convert.ToInt32(tData.ToString());

回答1:

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

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

回答2:

You should use:

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

回答3:

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);
