(Mono C#) Demonstrates how to Handle Large Integers in JSONSee more JSON ExamplesDemonstrates how to handle large integers in JSON. (Integers larger than what can fit in a 32-bit signed integer.)
// Let's say your JSON has this: // { // "id": 20000000001234567 // } Chilkat.JsonObject json = new Chilkat.JsonObject(); bool success = json.LoadFile("qa_data/json/large_int.json"); if (success == false) { Debug.WriteLine(json.LastErrorText); return; } // The integer is too large for a 32-bit signed integer that is returned by IntOf. // The result will be something that wrapped around and could be negative. // In this case it would be: -543893881 int id = json.IntOf("id"); Debug.WriteLine("id: " + Convert.ToString(id)); // The solution is to read the integer value as a string, and then use the features in your programming language // to convert from a string to a 64-bit integer. // // Alternatively, you may wish to simply hold the value as a string. If, for example, the integer simply references // an order ID, an account ID, etc., then there's no need to convert to an integer value. You're not going to be doing // mathematical operations on it anyway. This is usually the case for large integers -- they typically exist // in JSON as an account ID. // You can get any JSON value as a string: string accountId = json.StringOf("id"); Debug.WriteLine("accountId: " + accountId); // Sample output: // id: -543893881 // accountId: 20000000001234567 |
