Visual Studio: How to break on handled exceptions?
I would like Visual Studio to break when a handled exception happens (ie I don't just want to see a "First chance" message, I want to debug the actual exception).
eg I want the debugger to break at the exception:
try
{
System.IO.File.Delete(someFilename);
}
catch (Exception)
{
//we really don't care at runtime if the file couldn't be deleted
}
I came across these notes for Visual Studio.NET:
1) In VS.NET go to the Debug Menu >> "Exceptions..." >> "Common Language Runtime Exceptions" >> "System" and select "System.NullReferenceException"
2) In the bottom of that dialog there is a "When the exception is thrown:" group box, select "Break into the debugger"
3) Run your scenario. When the exception is thrown, the debugger will stop and notify you with a dialog that says something like: "An exception of type "System.NullReferenceException" has been thrown. [Break] [Continue]"
Hit [Break]. This will put you on the line of code that's causing the problem.
But they do not apply to Visual Studio 2005 (there is no Exceptions option on the Debug menu).
Does anyone know where the find this options dialog in Visual Studio that the "When the exception is thrown" group box, with the option to "Break into the debugger"?
Update: The problem was that my Debug menu didn't have an Exceptions item. I customized the menu to manually add it.
With a solution open, go to the Debug - Exceptions (Ctrl+D,E) menu option. From there you can choose to break on Thrown or User-unhandled exceptions.
EDIT: My instance is set up with the C# "profile" perhaps it isn't there for other profiles?
在VS2005中有一个“异常”窗口...在调试时尝试Ctrl + Alt + E，然后单击'Thrown'复选框以选择要停止的异常。
Check this out on msdn, it explains how to set this up.
Essentially, here are the steps (during debugging):
On the Debug menu, click Exceptions.
In the Exceptions dialog box, select Thrown for an entire category of exceptions, for example, Common Language Runtime Exceptions.
-or-
Expand the node for a category of exceptions, for example, Common Language Runtime Exceptions, and select Thrown for a specific exception within that category.
