String output: format or concat in C#?

Question

Let\'s say that you want to output or concat strings. Which of the following styles do you prefer?

• var p = new { FirstName = \"Bill\", LastName = \"Ga

Nice one!

Just added

        s.Start();
        for (var i = 0; i < n; i++)
            result = string.Concat(p.FirstName, " ", p.LastName);
        s.Stop();
        ceElapsedMilliseconds = s.ElapsedMilliseconds;
        ceElapsedTicks = s.ElapsedTicks;
        s.Reset();

And it is even faster (I guess string.Concat is called in both examples, but the first one requires some sort of translation).

1000000 x result = string.Format("{0} {1}", p.FirstName, p.LastName); took: 249ms - 3571621 ticks
1000000 x result = (p.FirstName + " " + p.LastName); took: 65ms - 944948 ticks
1000000 x result = string.Concat(p.FirstName, " ", p.LastName); took: 54ms - 780524 ticks
