try again in C# exception handling

[Guest]

I'm new to C#. Please answer my following questions about c# exception
handling.

What happens and how an exception handled if it occurs in "catch" block
while already processing another exception.

In an exception "catch" block I am showing a dialog box to user with option
of "try again" or "cancel". How can I implement the "try again" option, is
there any way in c# exception handling to run the same exception statement
again.

regards,
Adil

You can use nested try/catch blocks in your code. If some operation in a
catch block might raise an exception, put it into a try/catch block of its
own.

Hi Adil,

Stick it in a loop.

Pseudo-code-ish:

done = false;

while !done
{

try
{
codeThatMightFail

done = true;
}

catch
{
if( !( DialogBox = TryAgain )) done = true;
}

}


Nothing additionally C# specific here.

Hope this helps.

Yeah, I wish .NET had the continue statement.
