If you mean like:

C#

try
{
    // Do some work...

    try
    {
        // Do some work...

    }
    catch (Exception)
    {
        throw;
    }
}
catch (Exception)
{
    throw;
}

Then, yes, you can though I'd look very deeply at your design: this is not good practice.

But is it not as good as writing below code?
try
{
}
catch(ArgumentException aexec)
{
}
catch(Exception exc)
{
}

OP asked about nested try/catch - and while you example is an excellent way to handle multiple exception types, you can not have a block of code between the catch statements. Point: It's not the same thing, and both have its uses.

Thanks for the reply. AFAIK nested try catch is not a good practice. I would rather use a method for internal try-catch part and call the method there.

I do not doubt that your answer is correct and to the point to the question but all I was saying is you should have also mentioned about the best practice thing.
Cheers!

ahh, well, best practice ... why not say fashionable? It is after all closer to the truth :) It's like common sense, it isn't common ...
