Hi coletteck8,

Er...

This is ASP.NET formatting.

Response.Output.Write can format a string, this actually is kind of like sprintf in other languages.


The things in {0} is kind of a backreference per say. The {0} means the first argument after this one, meaning f. The {1} indicates the next one, which is ToCelsius(f), and I believe you can have up to {2} in most cases.

So, if in the above, every {0} just means INSERT f there.

THe second one is {1:f}. The 1 is self-explanatory, insert the ToCelsius(f) there, but the f I believe is to make ToCelsius(f) a float, but I'm not sure...

Regards,
Zyloch

No problem, glad to help =)

I'm actually not too good at ASP, but many of the experts in this area know more than one web language at least partially.
