In my catch block I want to make sure that the exception raised was indeed for Access Denied. Is there a way I can get the error code for it ? Win32 error code for Acceess Denied is 5. I dont want to search the error message for denied string or anything like that.

But Joel's answer will also do the trick for sure. –KyleM Aug 1 '11 at 0:07 You should only catch the exact type of exception you expect; catching Exception is almost always a bad code smell. –Bevan Aug 1 '11 at 1:06 @Bevan catching Exception is almost always good idea. Because you don't have to show a message at once — an every class shouldn't know does the app works with GUI or terminal. So you just have to save an exception ID to show it in a far far away. No need to catch every exception exclusively to do the same thing. At least it was the way I worked in C++. Now I'm work with C#, but don't

Complete Example for Error Handlers Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 This https://msdn.microsoft.com/en-us/library/bb397417.aspx code example includes elements for both page-level and application-level exception handling. Code Example Files The example consists of the following files: Web.config Global.asax Default.aspx ExceptionUtility (to be put in the App_Code folder) GenericErrorPage.aspx HttpErrorPage.aspx Http404ErrorPage.aspx DefaultRedirectErrorPage.aspx Web.config The following example shows the Web.config file. The customErrors section specifies how to handle errors that occur with file types that are mapped to ASP.NET, such as .aspx, .asmx, and .ashx files. (In IIS 6.0 and in IIS 7.0 in classic mode, static content files such as .html and .jpg files are not mapped to ASP.NET.) The settings in the example customErrors section cause any unhandled HTTP 404 (file not found) errors to be directed to the Http404ErrorPage.aspx file. These HTTP 404 errors would occur if a request were made for an .aspx file, .asmx file, and so on and if the requested file did not exist. All other unhandled errors in ASP.NET files are directed to the DefaultRedirectErrorPage.aspx file. If static content files are not handled by ASP.NET, a r

ASP.NET development is not much different. Every developer, especially beginners, will make errors whenever tries to create anything useful. Because of that, we need methods and tools for error handling. Fortunately, ASP.NET provides different ways to find, log or even try to correct errors when happened. There are three different kinds of errors you can produce. 1. Syntax errors Syntax errors occur during development, when you make type mistake in code. If you use anything more advanced than Notepad every syntax error will be marked in code editor. For example, Visual Studio or Visual Web developer will underline error with red zigzag line. If you go with mouse pointer over the error, you'll get more information, like in image bellow: Image 1: Syntax error in Visual Web Developer Even if you don't notice this underlined text, Visual Studio or Visual Web Developer will inform you again when you try to compile application. Because of that, syntax errors maybe looks horrible especially for beginners, but they are easy to detect and solve. 2. Run time errors Great thing in web development is that you can easily get notification by e-mail (or on some other way) every time when error occurs. It could be very disappointing if you don't have some error message reporting system and then accidentally discover that some page doesn't work for a months. All run time errors in ASP.NET we can divide in two groups: a) Handled errors - These errors are predicted and we manage them with Try...Catch..
