推荐答案

由于一些奇怪的原因，你.aspx不是格式良好。请检查一下。尝试使用此文件编译ASP.NET解决方案;它没关系，检查它是否正确部署（很可能，因为你可能使用嵌入在Visual Studio中的HTTP服务器，在这种情况下，你在项目中有完全相同的文件）。



此外，对于简单的检查，您可以将.aspx文件重命名为.xml并使用任何Web浏览器进行测试;它会显示文件中的错误点。

By some weird reason, you .aspx is not well-formed. Please check it up. Try to compile your ASP.NET solution with this file; it it's fine, check up that it is deployed correctly (most likely, it is, because you probably work with the HTTP server embedded in Visual Studio, in this case, you have exact same files an in the project).

Also, for a simple checkup, you can rename your .aspx file to .xml and test with any Web browser; it will show you the wrong point in the file.

只需输入Application_error Global.asax中的标签





protected void Application_Error（object sender，EventArgs e）

{



}







无需添加任何错误处理代码

just put Application_error tag in Global.asax


protected void Application_Error(object sender, EventArgs e)
{

}



No need to add any error handling code inside

I think you added  <httpErrors errorMode="Custom" existingResponse="PassThrough"/>
in <system.webserver> (web.config).
Please remove this for a while so that you can see the actual error.
After you get error you can search for actual error.
