Do Visual Studio ignore exceptions?

Question

I use exceptions to test the control in Silverlight 4. When I throw an invalid input exception, VS 2010 displays a popup and stops the program. I ignore this and resume the program, and everything continues normally (since the exception is used to signal a validation error.) Is there a way to mark this exception as ignored?

I follow this tutorial .

Answer 1

Debugging → Exceptions → Uncheck

Answer 2

Menu, Debugger, Exceptions ...

In this dialog box, you can remove the checkmark in the thrown column for one exception, for the entire namespace. You can add your own. etc.etc.

Answer 3

I tried to create a general solution so that I could use any call where I want the debugger not to stop if I get an exception, but I didn’t get it working.

Any ideas are welcome. But the obvious solution would be the VS2010 debugger to support the DoNotBreakIfException flag :-)

My idea was to replace code like

srng = TrySpecialCells(sheet, cellType); 

by

 srng = ExcelTry(() => sheet.Cells.SpecialCells(cellType)); 

where ExcelTry is

 [System.Diagnostics.DebuggerNonUserCode()] [System.Diagnostics.DebuggerHidden()] private static T ExcelTry<T>(Func<T> call) { try { return call(); } catch (TargetInvocationException) { return default(T); } catch (COMException) { return default(T); } } 

Answer 4

I got [System.Diagnostics.DebuggerHidden()] to work if I also selected

Debugging> Options> Debugging> General> Include only my code (only for managed).

I turn to the Excel object model a lot, and I really like being able to run the debugger and catch all exceptions, as my code is usually an exception. However, the Excel API throws many exceptions.

 // [System.Diagnostics.DebuggerNonUserCode()] works too [System.Diagnostics.DebuggerHidden()] private static Excel.Range TrySpecialCells(Excel.Worksheet sheet, Excel.XlCellType cellType) { try { return sheet.Cells.SpecialCells(cellType); } catch (TargetInvocationException) { return null; } catch (COMException) { return null; } } 

Answer 5

You can disable some throw block surrounded in the block

 #if !DEBUG throw new Exception(); /// this code will be excepted in the debug mode but will be run in the release #endif 

Answer 6

Assuming this is the property above that throws the exception, it looks like it should work, but apparently not: [System.Diagnostics.DebuggerHidden()] :

  private String name; [System.Diagnostics.DebuggerHidden()] public String Name { get { return name; } set { if (String.IsNullOrWhiteSpace(value)) { throw new ArgumentException("Please enter a name."); } } } 

Answer 7

In Visual Studio 2015, there is an exception settings window for this.

Debugging> Windows> Exclusion Settings
