For example, if your application unsuccessfully
Exception Handling In Asp.net C#
tries to log in to a database, it should not display an error message that includes the user name it is using. There are a number of ways to control error messages, including the following: Configure the application not to show verbose error messages to remote users. (Remote users are those who request pages while not working on the Web server computer.) You can optionally redirect errors to an application page. Include error handling whenever practical and construct your own error messages. In your error handler, you can test to see whether the user is local and react accordingly. Create a global error handler at the page or application level that catches all unhandled exceptions and routes them to a generic error page. That way, even if you did not anticipate a problem, at least users will not see an exception page. To configure the application to turn off errors for remote users In the Web.config file for your application, make the following changes to the customErrors element: Set the mode attribute to RemoteOnly (case-sensitive). This configures the application to show detailed errors only to local users (that is, to you, the developer). Optionally include a defaultRedirect attribute that points to an

For the client's computer, you'll want to redirect to an error page with an appropriate error message, perhaps including the exception message and stack trace if you want. On the server, you'll probably want to do some logging, either to the event log or to a log file. try { .... } catch (Exception ex) { this.Session["exceptionMessage"] = ex.Message; Response.Redirect( "ErrorDisplay.aspx" ); log.Write( ex.Message + ex.StackTrace ); } Note that the "log" above would have to be implemented by you, perhaps using log4net or some other logging utility. share|impr
