Hello,

I'm using a Stringbuilder to building dynamic HTML, and I was wondering
how long it can get before it gives up. I won't know the length of the
HTML until it's finished building it. I've read a few articles that
suggest setting an initial size when you instantiate it, but will that
work even if I don't know how much I'm storing?

Any help would be appreciated. Thanks!

It looks like the maximum characters is the MaxValue of an Int32 which is
2,147,483,647.

It'll be limited by the largest contiguous block of virtual memory in the
large object heap. For a typical 32bit machine, you can expect that to be a
couple hundred megabytes - perhaps as much as 1 Gb under the best
circumstances.
