在C sharp中的ASP.NET中的Http 404错误消息 [英] Http 404 error messages in ASP.NET in C sharp

问题描述

我的网站项目显示了http 404错误消息。我只是在localhost中设计基本级别的链接逻辑。我不知道哪里错了。可以告诉我哪里出错了？我认为它非常简单，不应该显示错误信息。





这是我在C＃中的代码。

My website projects shows the http 404 error message. I just design the basic level link logic in my localhost. I don't know where it is wrong. Can tell me where is wrong? I think it is very easy sample and should not show the error message.


This is my code in C#.

protected void CHWebsiteLink_Click(object sender, EventArgs e)
    {
        LinkButton LnkB = sender as LinkButton;
        string strLinkButton = string.Empty;
        strLinkButton = LnkB.Text;

        #region Link Logic
        try
        {
            if (strLinkButton == "中文")
            {
                Response.Redirect("~/_form/Default.aspx");
            }
            else if (strLinkButton == "English")
            {
                Response.Redirect("~/_form/frmPage.aspc");
            }
        }
        catch (Exception ex)
        {
            Response.Redirect(ex.Message);
        }
        finally
        {
            System.Threading.Thread.Sleep(2000);
        }
        #endregion
    }

我尝试过：



我检查了我的aspx文件网址是否正确。

What I have tried:

I have checked my aspx file url that is correct.

推荐答案

你可以允许错误通过抛出或将其添加到控件（如标签）来在网站上显示的消息。但是，如果你调试它，你会很快发现问题。

You can allow the error message to show on the website by throwing it or adding it to a control such as a label. However, if you debug this, you'll find the issue very quickly.

我只推荐这个用于调试目的。您可以使用@RyanDev建议的方法或执行以下操作。 #if DEBUG ... #endif语句用于确保仅在调试模式中显示错误消息。

I'll only recommend this for debugging purposes only. You can use the method suggested by @RyanDev or do the following. The #if DEBUG...#endif statement is to make sure the error message will be displayed only in debug mode.

catch (Exception ex)
            {
                #if DEBUG
                    Response.Write(ex.Message);
                #endif
            }

在生产中，您可以使用错误记录模块和处理程序（ELMAH）记录错误并将请求重定向到通用错误页面。

或者只是将任何错误重定向到一般错误页面，你不想泄漏向对手提供任何信息。

On production, you can use Error Logging Modules And Handlers (ELMAH) to log the errors and redirect the request to the generic error page.

Or just redirect any error to generic error page, you don't want to leak out any information to the adversary.
