TIPS: Error handling in ASP.Net 2.0
Posted by: Rickie Lee http://rickie.cnblogs.com
In order to avoiding generating an ugly error message to end users, we can handle it in two ways.
1. Add a custom error page to web site. When an unhandled error occurs, a user-friendly web page will come and ask the users to come back later.
2. Add a Global.asax file into web site, where you can add log this kind of errors.
Follows the following steps to take care:
1. Modify Application_Error method in Global.asax file like this:
void Application_Error(object sender, EventArgs e)
{
// Code that runs when an unhandled error occurs
// Log all unhandled errors
}
2. Config web.config file, add a new child of the <system.web> element:
<customErrors mode="RemoteOnly" defaultRedirect="BasePage/Error.aspx" />
3. Add a user-friendly error-handling web page, which appears when an unhanlded error happens.
Add some conent like this:
