Question

I am working with Visual Studio 2010, MVC 3 and C#. I am creating some highcharts and need to have the x-axis be a date. I am pulling the dates from a database and adding them to and array that will then be passed to highcharts. I think highcharts requires the dates to be in millisecond format. Ho do I go about converting a DateTime of ’12/20/2011 5:10:13 PM” for example to milliseconds?

Answer 1

Once you figure out what you want to calculate milliseconds from, you can just take one DateTime object from another to get a TimeSpan object. From TimeSpan you can get TotalMilliseconds.

In other words, if start and end are DateTime objects, you can do this:

double milliseconds = (end - start).TotalMilliseconds;
