StringBuilder Q

[Vai2000]

Coming out from the VC++ Background I was trying to clear the Stringbuilder
object with sb.Length=0
Is this approach OK? If not what's the alternative, looks like I have run
into an exception when the size of the SB is gargantous!! like > 200MB

Please advice

TIA

Yes, it's fine to clear it that way.

Yup, that should be fine. You might want to consider creating a new
instance though instead - if you reuse a StringBuilder a lot, it will
end up getting promoted to later generations, which may not be a good
idea. (It then becomes more expensive to use, because changes to its
reference fields require more complicated operations to keep the GC
efficient.)

Similar cool trick: To delete the last character in a StringBuilder,
sb.Length--;
