How do I get time diiference between two dates in milliseconds in C#?

Question

In Javascript I can use var d = new Date(); var n = d.getTime(); to get the time in milliseconds. Is there any similar method in C#?

Answer 1

Subtracting a DateTime from another DateTime returns a TimeSpan.

DateTime d1 = DateTime.UtcNow;
DateTime d2 = DateTime.UtcNow.AddDays(1);
TimeSpan ts = d2 - d1;
Console.WriteLine(ts.TotalMilliseconds);
// Outputs 86400000
