simple String formatting question

I am attempting to output a trace with details of the db id of a price
using:

Trace.WriteLine("price id(first price): {0}",evnt.Prices[0].Id);

Wher the Id is a string. I expect from this to output

price id(first price): [priceid]

instead I get:
[priceid]: price id(first price):{0}

Can anyone explain what is going wrong here. I have managed to fix this
issue with the following:

Trace.WriteLine(String.Format("price id(first price):
{0}",evnt.Prices[0].Id));

But why does the string format incorrectly in the first instance?

Thanks, Richard

That call is to Trace.WriteLine(string, string). The first parameter
is the message to write, and the second parameter is the category
name. It's *not* a formatting call.
