Question

I have the following line of code in my c# MVC2 Project:

string.Format(@"{0\:HH\:mm}", new TimeSpan(0))

This line is resulting in the following exception:

System.FormatException: Input string was not in a correct format.

Can anybody tell me why? I’m using C#, asp.net, mvc2, and .net framework 4

Answer 1

Two problems. Firstly you should not be escaping the first :. This is necessary as a separator and should not be escaped.

The second is that HH should be hh.

This runs without errors:

string.Format(@"{0:hh\:mm}", new TimeSpan(0))
