本文提供了两种方法来获取网站的根目录URL及物理路径。通过使用HttpContext和HttpRequest对象，可以灵活地适应不同的部署环境，无论是直接安装在Web站点还是安装在虚拟子目录下。

/// <summary>
/// 取得网站的根目录的URL
/// </summary>
/// <returns></returns>
public static string GetRootURI()
{
string AppPath = "";
HttpContext HttpCurrent = HttpContext.Current;
HttpRequest Req;
if (HttpCurrent != null)
{
Req = HttpCurrent.Request;

string UrlAuthority = Req.Url.GetLeftPart(UriPartial.Authority);
if (Req.ApplicationPath == null || Req.ApplicationPath == "/")
//直接安装在 Web 站点
AppPath = UrlAuthority;
else
//安装在虚拟子目录下
AppPath = UrlAuthority + Req.ApplicationPath;
}
return AppPath;
}
/// <summary>
/// 取得网站的根目录的URL
/// </summary>
/// <param name="Req"></param>
/// <returns></returns>
public static string GetRootURI(HttpRequest Req)
{
string AppPath = "";
if(Req != null)
{
string UrlAuthority = Req.Url.GetLeftPart(UriPartial.Authority);
if (Req.ApplicationPath == null || Req.ApplicationPath == "/")
//直接安装在 Web 站点
AppPath = UrlAuthority;
else
//安装在虚拟子目录下
AppPath = UrlAuthority + Req.ApplicationPath;
}
return AppPath;
}
/// <summary>
/// 取得网站根目录的物理路径
/// </summary>
/// <returns></returns>
public static string GetRootPath()
{
string AppPath = "";
HttpContext HttpCurrent = HttpContext.Current;
if (HttpCurrent != null)
{
AppPath = HttpCurrent.Server.MapPath("~");
}
else
{
AppPath = AppDomain.CurrentDomain.BaseDirectory;
if (Regex.Match(AppPath, @"\\$", RegexOptions.Compiled).Success)
AppPath = AppPath.Substring(0, AppPath.Length - 1);
}
return AppPath;
}
