Hi @zequion , Welcome to Microsoft Q&A,

Updated: You need to generate a .pdb file to know the line number.

You can try the following:

Breakpoints: Set a breakpoint at the line of code where you suspect the error will occur. When program execution reaches a breakpoint, it pauses, allowing you to examine the current variable values and program state.

Exceptions Window: When an exception is caught, Visual Studio lists it in the Exceptions Window. You can view the details of the exception, including error message, stack trace, and more.

Debug output: In the catch block, you can use methods such as Debug.WriteLine() or Console.WriteLine() to output error messages or other debugging information. This can help you view exception information in the console or output window.

"Continue" and "Step Out": During debugging, you can choose "Continue" or "Step Out" to continue executing the program or jump out of the current function.

Best Regards,

Jiale

The error occurs inside a loop sometimes and it is difficult to find the line that produced the error. If you could go back in catch() it would be helpful.

Can't you find the corresponding error through the error message in catch? What you are looking for should be progressive positioning. Finally, confirm the position through the break point. You can use the logging library in catch to log errors. Use throw properly.https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/statements/exception-handling-statements

Apparently I need to generate a .pdb file to know the line number. I thought VS already allowed you to go backwards.
