[c#] How do I get TimeSpan in minutes given two Dates?

To get TimeSpan in minutes from given two Dates I am doing the following

int totalMinutes = 0;
TimeSpan outresult = end.Subtract(start);
totalMinutes = totalMinutes + ((end.Subtract(start).Days) * 24 * 60) + ((end.Subtract(start).Hours) * 60) +(end.Subtract(start).Minutes);
return totalMinutes;

Is there a better way?

I would do it like this:

int totalMinutes = (int)(end - start).TotalMinutes;

Why not just doing it this way?

DateTime dt1 = new DateTime(2009, 6, 1);
DateTime dt2 = DateTime.Now;
double totalminutes = (dt2 - dt1).TotalMinutes;

Hope this helps.

double totalMinutes = (end-start).TotalMinutes;

See TimeSpan.TotalMinutes:

Gets the value of the current TimeSpan structure expressed in whole and fractional minutes.
