In ASP.NET MVC RC3 with Razor - @ String.Format ("{0: hh: mm: ss}", timespan) errors - error?

Question

The following errors with a FormatException exception:

<td class="numeric">@String.Format("{0:hh:mm:ss}", testrun.ExecutionTime)</td> 

Where ExecutionTime is a TimeSpan. This format string is valid. Is this a mistake or am I missing something obvious (given the late hour - the last one is probably this).

Answer 1

Try to do :

 String.Format("{0:hh\\:mm\\:ss}", testrun.ExecutionTime) 

Answer 2

Aren't you looking for @testRun.ExecutionTime.ToString("format here") method?
