无法映射路径'/'..net 4.0

Question

我有一个.net应用程序,我刚刚在visual studio 2010中打开,当它在启动时询问我时转换为4.0.我去尝试构建网站,我收到此错误:

Failed to map the path '/'.

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

我尝试了最流行的解决方案,我发现谷歌(替换和../与〜/但没有任何...)

更新:

Lookups构造函数:

public Lookups()
{           
    _dirPath = System.Web.HttpContext.Current.Server.MapPath("/") + _xmlPath;           
}

Answer 1

我知道这是旧的问题,但是如果你正在针对IIS运行那么记录

控制台中的"iisreset"可能有助于解决"无法映射路径'/'." 问题.在IIS中重命名站点后,我遇到了这个问题.

Answer 2

我只是试图在Microsoft Step Step中进行练习,并且在尝试预编译ASP.NET应用程序时遇到了这个问题.

这就是我如何克服这一点 - 我花了一天时间才弄明白!

当您打开Visual Studio命令提示符以执行构建/预编译时,必须右键单击并选择"以管理员身份运行".

这就是我在尝试运行此aspnet_compiler时所花费的全部内容-v DeployThis C:\ DeployThis -f -u

Answer 3

试试System.Web.HttpContext.Current.Server.MapPath("~/").请注意~.
