Formatting a TimeSpan to look like a time zone offset

How can I format a TimeSpan object to look like a time zone offset, like this:

+0700

or

-0600

I'm using GetUtcOffset to get an offset, and its working, but its returning a TimeSpan object.

This code:

var timeSpan = new TimeSpan(2, 30, 0);
Console.WriteLine(new DateTimeOffset(2000, 1, 1, 1, 1, 1, timeSpan).ToString("zzz"));
Console.WriteLine(new DateTimeOffset(2000, 1, 1, 1, 1, 1, -timeSpan).ToString("zzz"));

outputs:

+02:30
-02:30

Try something like:

var timespan = new TimeSpan(-5,0,0); // EST
var offset = String.Format("{0}{1:00}{2:00}",(timespan.Hours >= 0 ? "+" : String.Empty),timespan.Hours,timespan.Minutes);

I add the + when the number is non-negative (for negative numbers a - should be output).

If you're using .Net 4.0 or above, you can use the ToString method on timespan with the hh and mm specifier (not sure if it will display the + and - signs though):

TimeSpan span = new TimeSpan(7, 0, 0);
Console.WriteLine(span.ToString("hhmm"));

If not, you can just format the Hours and Minutes properties along with some conditional formatting to always display the + and - signs:

TimeSpan span = new TimeSpan(7, 0, 0);
Console.WriteLine("{0:+00;-00}{1:00}", span.Hours, span.Minutes);

I think you could use this:

String.Format("{0:zzz}", ts);
