Java System.currentTimeMillis() equivalent in C#

Question

What is the equivalent of Java\'s System.currentTimeMillis() in C#?

Answer 1

We could also get a little fancy and do it as an extension method, so that it hangs off the DateTime class:

public static class DateTimeExtensions
{
    private static DateTime Jan1st1970 = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
    public static long currentTimeMillis(this DateTime d)
    {
        return (long) ((DateTime.UtcNow - Jan1st1970).TotalMilliseconds);
    }
}
