using and error trapping

[Mike P]

I've just started using the 'using' keyword for database connections
etc. Is it not possible to use try catch blocks with using? And if so,
how do you trap errors when using using?

It is possible to do so.

If you want to continue with using, try this:

try
{
using (SomeObject obj = new SomeObject())
{
... something that can go wrong here
}
}
catch (YourExceptionClassHere ex)
{
}

Or you can nest the try/catch block inside the using block.

Hi,

in exactly the same way:
try{
using() {}
}catch{}

or
using(){
try{
}catch{}
}

In the first case the connection will be closed (and out of context)
in the catch block

In the second the connection might still be open and in context so you
can access it
