获取根目录的URL例如http://localhost:51898_实用技巧

复制代码 代码如下:

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;
}
