or
或者
string URL = Server.MapPath("/");

your URL will display resources in your link like this:
您的 URL 将在您的链接中显示资源，如下所示：
"file:///d:/InetPUB/HOME/Index/bin/Resources/HandlerDoc.htm"
But if you want your URL to show only virtual path not the resources location, you should do
但是如果你想让你的 URL 只显示虚拟路径而不是资源位置，你应该这样做
string URL = HttpRuntime.AppDomainAppVirtualPath;
then, your URL is displaying a virtual path to your resources as below
然后，您的 URL 将显示资源的虚拟路径，如下所示

I created a website with ASP.Net WebForms where you can see the result of using all forms mentioned in previous responses from a site in Azure.
我使用 ASP.Net WebForms 创建了一个网站，您可以在其中查看使用 Azure 中的站点的先前响应中提到的所有表单的结果。
http://wfserverpaths.azurewebsites.net/
http://wfserverpaths.azurewebsites.net/
Summary:
概括：
Server.MapPath("/") => D:\home\site\wwwroot\
Server.MapPath("~") => D:\home\site\wwwroot\
HttpRuntime.AppDomainAppPath => D:\home\site\wwwroot\
HttpRuntime.AppDomainAppVirtualPath => /
AppDomain.CurrentDomain.BaseDirectory => D:\home\site\wwwroot\
HostingEnvironment.MapPath("/") => D:\home\site\wwwroot\
HostingEnvironment.MapPath("~") => D:\home\site\wwwroot\

Best choice is using
最好的选择是使用
AppDomain.CurrentDomain.BaseDirectory
because it's in the system namespace and there is no dependencyto system.web
因为它在系统命名空间中并且不依赖于system.web
this way your code will be more portable
这样你的代码会更便携
