Exit Try/Catch to prevent code after from being run

Question

I've got for example a try/catch in my method:

    }
    catch (OurCustomExceptionObject1 ex)
    {
       txtErrorMessage.InnerHtml = "test 1";
    }
    catch(OurCustomExceptionObject2 ex)
    {
        txtErrorMessage.InnerHtml = "test 2";
    }
    catch (OurCustomExceptionObject3 ex)
    {
        txtErrorMessage.InnerHtml = "test 3";
    }

    ... rest of code here is being executed after the try/catch

I do not want the rest of code to run if any of the exceptions are caught. I'm handling the exceptions. I heard do not use Exit Try for some reason. Is that true, it's bad to do this? Is this the right way to halt execution of code thereafter the catch statement?

Answer 1

Either return in the catch-block, rethrow the exception, or move the code from below the try-block inside the try-block.

Answer 2

Two options immediately come to mind:

1. return straight from inside each catch (as BlueRaja suggested)
2. set a flag (e.g., errorOccurred) within the catch blocks for the exceptions you don't want to allow, then put if (errorOccurred) return; after the whole try/catch block

The latter might be more readable to other developers, since it's easy to skim past what happens inside a catch to figure out what happens afterward. Seeing a blatant if (errorOccurred) return; makes it pretty hard to misunderstand what happened.
