使用Server.Mappath（） [英] Server.MapPath()

问题描述

我想使用使用Server.Mappath（）方法IM为了映射虚拟目录 我创建它的物理路径。

I want to use Server.MapPath() method im order to map a virtual directory I created to its physical path.

的事情是，.NET环境不承认使用Server.Mappath（）。

The thing is that the .net environment doesn't recognize Server.MapPath().

谷歌告诉我，我应该HttpContext.Current.Server使用的System.Web使用， 但HttpContext的是，尽管我使用的System.Web无法识别。 （而且我已经检查 - HttpContext的IS的System.Web中的类之一）

Google told me I'm supposed to use HttpContext.Current.Server using System.Web, but HttpContext isn't recognized in spite of me using System.Web. (And I've checked - HttpContext IS one of System.Web's classes)

帮助？

推荐答案

如果你有一个Web应用程序，您应具有自动引用 System.Web.dll中，你应该有机会获得 System.Web.HttpContext 类。请检查您是否不小心删除了参考。您将需要一个使用的System.Web; 语句访问的HttpContext 类，而无需指定完整的命名空间。

If you have a web application, you should automatically have a reference to System.Web.dll, and you should have access to the System.Web.HttpContext class. Check that you haven't accidentally removed the reference. You would need a using System.Web; statement to access the HttpContext class without specifying the complete namespace.

如果你没有一个Web应用程序，你将有一个referece添加到 System.Web.dll中来获得访问的HttpContext 类，但不会帮助你一点。由于你是不是在一个Web应用程序，没有HTTP上下文，也没有Web根文件夹中，这样你就不能使用MapPath方法。

If you don't have a web application you would have to add a referece to System.Web.dll to get access to the HttpContext class, but that would not help you a bit. As you are not in a web application, there is no HTTP context and there is no web root folder, so you can not use the MapPath method.
