It seems to be string week in .NET blog land. I thought I'd plop this link to the API docs and other blog articles in here for my own sake.

Mike mentions using format strings instead of concatenation. It's a habit I've been into for a while. Moreso than using string builders, which I really need to do more often, instead of being a (bad) lazy programmer and concatenating stuff.

I like the control you get doing:

string var = string.Format("{0} {1} - {3}", blah, foo, bar);

over:

string var = blah + " " + foo + " - " + bar;

and it's far less verbose than:

StringBuilder sb = new StringBuilder();

sb.Append(blah);

sb.Append(" ");

sb.Append(foo);

sb.Append(" - ");

sb.Append(bar);

string var = sb.ToString();

Don't you think?
