What is exception handling in Visual Studio?

An exception is a response to an exceptional circumstance that arises while a program is running, such as an attempt to divide by zero. Exceptions provide a way to transfer control from one part of a program to another. VB.Net exception handling is built upon four keywords - Try, Catch, Finally and Throw.


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?


There is an 'exceptions' window in VS2005 ... try Ctrl+Alt+E when debugging and click on the 'Thrown' checkbox for the exception you want to stop on.


Took me a while to find the new place for expection settings, therefore a new answer.

Since Visual Studio 2015 you control which Exceptions to stop on in the Exception Settings Window (Debug->Windows->Exception Settings). The shortcut is still Ctrl-Alt-E.

The simplest way to handle custom exceptions is selecting "all exceptions not in this list".

From Visual Studio 2015 and onward, you need to go to the "Exception Settings" dialog (Ctrl+Alt+E) and check off the "Common Language Runtime Exceptions" (or a specific one you want i.e. ArgumentNullException) to make it break on handled exceptions.

Step 1 Step 1 Step 2 Step 2


Check Managing Exceptions with the Debugger page, it explains how to set this up.

Essentially, here are the steps (during debugging):

  1. On the Debug menu, click Exceptions.

  2. 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.


A technique I use is something like the following. Define a global variable that you can use for one or multiple try catch blocks depending on what you're trying to debug and use the following structure:

if(!GlobalTestingBool)
{
   try
   {
      SomeErrorProneMethod();
   }
   catch (...)
   {
      // ... Error handling ...
   }
}
else
{
   SomeErrorProneMethod();
}

I find this gives me a bit more flexibility in terms of testing because there are still some exceptions I don't want the IDE to break on.
