为什么错误后显示ASP.NET代码文件? [英] Why ASP.NET Code File Shown after Error?

问题描述

这次我再次使用ASP.Net Query，;)

我的服务器正在更新时，我有以下代码与我们联系，如果有人填写该表，则显示错误消息，如"由于目标计算机拒绝...(IP地址:端口)而无法建立连接 b>"

然后我的原始问题从这里开始. . . .

(1)我不想显示的后端代码显示(用contact.aspx.vb编写)，该怎么办?

(2)我的电子邮件ID和密码在这种类型的错误期间显示，如何将所有错误放入404(如错误页面)，因此，如果服务器上发生任何错误或进程正在更新，则客户会看到错误页面而不是后端代码. /b>
欢迎您提供答案，教程或分步指南.

谢谢，

我的代码:

        mbltxt.Text = ""
        emailtxt.Text = ""
        subtxt.Text = ""

推荐答案

第二个问题.您可以通过将特定错误与特定错误页面相关联来进一步使用自定义错误处理. customErrors部分可以包含将特定错误与错误页面相关联的错误元素.

For your second problem. you can use custom error handling a step further by associating specific errors with specific error pages. The customErrors section can contain error elements that associate particular errors with error pages.

<configuration>
   <system.web>
     <customErrors mode="RemoteOnly" defaultRedirect="apperror.aspx"/>
     <error statusCode="404" redirect="404.aspx" />
  </configuration>
