Parse custom date format using JSON.Net

Question

I\'m receiving a JSON date in the following format:

\"launch_date\": 1250553600

How should I modify the following to include a custom DateT

Answer 1

Here is some code to do that:

// This is an example of a UNIX timestamp for the date/time 11-04-2005 09:25.    
double timestamp = 1113211532;

// First make a System.DateTime equivalent to the UNIX Epoch.    
System.DateTime dateTime = new System.DateTime(1970, 1, 1, 0, 0, 0, 0);

// Add the number of seconds in UNIX timestamp to be converted.    
dateTime = dateTime.AddSeconds(timestamp);

For your code:

    JsonConvert.DeserializeObject<NTask>(json);  

    public sealed class NTask
    {
        public DateTime launch_date { get; set; }

        public void SetLaunchDate(int timestamp)
        {
            // First make a System.DateTime equivalent to the UNIX Epoch.    
            var dateTime = new DateTime(1970, 1, 1, 0, 0, 0, 0);

            // Add the number of seconds in UNIX timestamp to be converted.    
            launch_date = dateTime.AddSeconds(timestamp);
        }
    }

Then when you are Deserializing the JSON, check to see if the launch_date is of type int or DateTime and switch how you set the object based on the type!

You're going to want to use a JSONConverter to help manage the translation. See this stackapps answer for more detail.
