C# Error Handling Techniques
C#. How should I be handing errors now? up vote 12 down vote favorite In Visual Basic I wrote just On Error Resume Next in the head of my program and errors were suppressed in the entire project. Here in C# I miss this feature very much. The usual try-catch handling for every single procedure is not only very time-intensive, it brings undesired effects. If an error is c# error handling class encountered, even if handled, the code doesn't continue from the point it occurred. With On Error Resume Next, the code continued from the point of error, skipping just the function call that caused the error. I am not deeply involved with C# yet, but maybe there exists in C# a better error handling than the primitive try-catch. I also would like to have the module or function name where the error occured as well as the the line number in my error message. The Exception class doesn't provide that features as far I know. Any ideas (managed, of course, without involving any process classes on my own application)? How do you handle the errors in bigger projects? I hope I do not have to add a try-catch to each method. Somehow C# throws many errors - that seems to be typical of the language. My Solution which I found to re-solve several of my problems: public partial class Form1 : Form { public Form1() { InitializeComponent(); } [STAThread] static void Main() { Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException); //setup global error handler Application.Run(new Form1()); } private static void Application_ThreadException(object sender, System.Threading.ThreadExceptionEventArgs e) { MessageBox.Show("Unhandled exception: " + e.Exception.ToString()); //get all error information wi
bashaApril 18, 20100 0 0 0 Syed Aslam Basha here from the Information Security Tools Team. We have “On Error Resume Next” feature in error handling in c# best practices VB.NET, which simply means during execution if error occurs c# error handling example with the current code step just go to next code step by passing the c# error handling patterns error. As such there is no “On Error Resume Next” in C#, but we can achieve the same using try catch statements tactically as http://stackoverflow.com/questions/11596045/i-miss-visual-basics-on-error-resume-next-in-c-how-should-i-be-handing-erro ; 1: try 2: { 3: File.Delete(FileNameWithPath); 4: } 5: 6: catch() 7: { 8: // do nothing 9: } A difference is still that in C# this works only for a single statement. You would need to repeat the block for each statement. However, it is https://blogs.msdn.microsoft.com/syedab/2010/04/18/on-error-resume-next-in-c/ not a good practice. -Syed Aslam Basha (syedab@microsoft.com) Microsoft Information Security Tools (IST) Team Test Lead -------------------------------------- Please leave a comment if the blog post has helped you.

for On Error Resume Next 2Contributors 2Replies 3Views 8 YearsDiscussion Span 8 Years Ago Last Post by jireh 0 8 Years Ago Guys, A challenge for us... for you I mean lol! Can anyone of you have any idea on how to make an equivalent code of On Error Resume Next of VB to C#?. Note: Don't use a try catch Regards, Jireh A conclusion is the place where you got tired of thinking. http://www.martin2k.co.uk/forums/index.php?showforum=4 http://www.a1vbcode.com/a1vbcode/vbforums/Forum3-1.aspx http://www.developerfusion.co.uk/forums/ShowForum.aspx?ignore1=forums&ignore2=Forum&ForumID=4 jireh 3 334 posts since Jul 2007 Community Member c# 0 Narue 5,707 8 Years Ago >Note: Don't use a try catch Erm, why? On Error is generally considered to be a huge wart of VB, so why would you want to avoid the superior equivalent in C# and try to emulate it? 0 Discussion Starter jireh 3 8 Years Ago ok... you can use a try catch but what if i have 100 lines of code, you mean to say you have to try catch it in 100 times? or arrrgggghhhh! please see below sample. private int Calculate(int x, int y) { x=x+y; y=y-x; Calculate=x+y; return Calculate } My problem is we don't know what line will the error occur. suppose the error will be in x=x+y; so it will resume in y=y-x; or the error will be in y=y-x; and again it must resume in Calculate=x+y; and please don't ask me why it must resume...Just help me to this issue please... that it must resume to next statement if there's an error... regards, Jireh × Isn't it about time forums rewarded their contributors?
