Best way to convert JavaScript date to .NET date

Question

Now what is the best way to convert th

Answer 1

Expanding on @Naraen's answer, my javascript date was in the following format:

Thu Jun 01 2017 04:00:00 GMT-0400 (Eastern Standard Time)

Which required two lower case d's for the day (dd) for the conversion to work for me in C#. See update to @Naraen's code:

DateTime.ParseExact(dateString.Substring(0,24),
                          "ffffd MMM dd yyyy HH:mm:ss",
                          CultureInfo.InvariantCulture);

Answer 2

You can convert your time to string before you send it and in the .net you should convert a string into datetime using one of datetime constructor. Datetime .net -> http://msdn.microsoft.com/en-us/library/system.datetime(v=VS.90).aspx You can use also a DateTime.Parse method -> http://msdn.microsoft.com/en-us/library/ms973825.aspx But you should deliver a correct form of string to server

Answer 3

Convert JavaScript into UTCString from Client side:

var testDate = new Date().toUTCString();

Parse it from C# code (you can fetch js date through webservice call).

DateTime date = DateTime.Parse(testDate);

If you want local time, like you are showing in your question the following would do it.

DateTime.ParseExact(dateString.Substring(0,24),
                              "ffffd MMM d yyyy HH:mm:ss",
                              CultureInfo.InvariantCulture);

If you are looking for GMT time, doing a dateObject.toUTCString() in Javascript in the browser before you send it to the server, would do it.

Ok here try this simple function which will convert your `double' representation of your Unix Timestamp

public static DateTime ConvertFromUnixTimestamp(double timestamp)
{
    DateTime origin = new DateTime(1970, 1, 1, 0, 0, 0, 0);
    return origin.AddMilliseconds(timestamp); 
}
