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

Question

The following errors with a FormatException:

<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 bug or am I missing something obvious (given the late hour - the latter is probably it).

Answer 1

Try escaping the :

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