up What is the best alternative “On Error Resume Next” for C#? up vote 12 down vote favorite 2 If I put empty catch blocks for my C# code, is it going to be an equivalent for VB.NET's "On Error Resume https://msdn.microsoft.com/en-us/library/ms973849.aspx Next" statement. try { C# code; } catch(exception) { } The reason I am asking this is because I have to convert a VB.NET code to C#, and the old code has ~200 "On Error Resume Next" statements although I am using a proper try {} catch {} in my new code, but is there is a better alternative? c# vb.net error-handling vb.net-to-c# share|improve this question edited Oct 25 '12 at 16:11 Peter Mortensen 10.2k1369107 asked Jan 28 '11 at 6:15 Neel 67621026 12 http://stackoverflow.com/questions/4825422/what-is-the-best-alternative-on-error-resume-next-for-c The lack of an alternative to On Error Resume Next wasn't just an unintentional oversight... Why do you possibly need this? If you explain the motivation behind your thoughts of doing this, I'm sure that someone here could give you a better solution. –Cody Gray Jan 28 '11 at 6:17 @Cody Gray - updated the reason of asking. Thanks –Neel Jan 28 '11 at 6:31 2 @MarkJ: Because even if (s)he leaves the code as VB.NET, it's still a good idea to replace On Error Goto Next with more structured exception handling (or none at all). –Cody Gray Jan 29 '11 at 2:04 4 @Cody It is an improvement to replace the error handling, but you have to assess how long it will take (how much it will cost) and whether the code needs substantial modifications. If the code works & doesn't need changing, there may be better things to do with the time instead. –MarkJ Jan 29 '11 at 14:21 1 @MarkJ: Fair enough. I don't disagree with you, I was just providing what I felt was a convincing argument for the other side. This is one of those design decisions you have to make. Do I stick with sloppy code that happens to work, or do I take the time to improve it for long-term benefits. I was assuming the reason the conversion was being undertaken was because the code didn't work exactly right as-is. Others situations may vary, an
of the vb.net world, I use the Try/Catch statement quite a bit for when it comes to errors, as the following. With Me https://www.daniweb.com/programming/software-development/threads/423676/try-catch-vs-on-error-resume-next .Text = "a" Try .Text += 1 Catch ex As Exception MsgBox("error: " & ex.Message, MsgBoxStyle.Critical) End Try MsgBox("a") .Text = "b" Try .Text += 1 Catch ex As Exception MsgBox("error: " & ex.Message, MsgBoxStyle.Critical) End Try MsgBox("b") End With For the first time today, I attempted to use the On Error Resume Next and it returned the on error results I needed; less lines of code and only results if an error occured. On Error Resume Next With Me .Text = "a" .Text += 1 MsgBox("a") .Text = "b" .Text += 1 MsgBox("b") End With My question is, even though quite clear to me: For such lines of code as above, is the On Error Resume Next appropriate on error goto and can I move on to the next part of my.app with no worries, ever?.thanx.in.adv,.Me. error vb.net â””(vb.net: codeorder.net)â”â””(DaniWeb: How to mark a thread as solved?)â”â””(.reality.: .Me ='s Life; .My ='s Univers.e/.al:.bytes.)â” codeorder 197 2,027 posts since Aug 2010 Community Member 3Contributors 6Replies 12Views 4 YearsDiscussion Span 4 Years Ago Last Post by codeorder 0 Oxiegen 88 4 Years Ago By using a Try...Catch statement you can catch the error and do something about it. It's a very useful debugging tool. However, you don't have to enclose every single piece of altering code in it's own statement. You can start the Try statement even before the line With Me and end it below the line End With, followed by the Catch statement with a messagebox displaying the error. With On Error Resume Next, you won't know if an error occured and on what line. So you have no way of knowing and thus can't do much about it. Also. Personally I feel that those types of error catching methods are depricated as
