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:
