 long a =(long) (DateTime.Parse("2011-3-29") - DateTime.Parse("1970-1-1")).TotalMilliseconds;

Create a Date Object
The Date object is used to work with dates and times. 

Date objects are created with the Date() constructor.

There are four ways of initiating a date:

new Date() // current date and time
new Date(milliseconds) //milliseconds since 1970/01/01
new Date(dateString)
new Date(year, month, day, hours, minutes, seconds, milliseconds)

                DateTime date = new DateTime(1970, 01, 01);
                DateTime date2 = date.AddMilliseconds(1301356800000);
                Response.Write(date + "<br/>");
                Response.Write((date2 - date).TotalMilliseconds);
                Response.End();
