Possible Duplicate:
Performance Cost Of ‘try’

I am being told that adding a try catch block adds major performance cost in the order of 1000 times slower than without, in the example of a for loop of a million. Is this true?

Isn’t it best to use try catch block as much as possible?

    From MSDN site:

    Finding and designing away
    exception-heavy code can result in a
    decent perf win. Bear in mind that
    this has nothing to do with try/catch
    blocks: you only incur the cost when
    the actual exception is thrown. You
    can use as many try/catch blocks as
    you want. Using exceptions
    gratuitously is where you lose
    performance. For example, you should
    stay away from things like using
    exceptions for control flow.
