Asp.net中的常用路徑

ASP.NET

記性不好,好多次都被路徑問題給攔住了.我現在想得到一個資源的全URL路徑,因此首先想得到網站當前的域名,埠和虛擬目錄.看下錶

底下這張表就是各種跟 Browser Request 的網址相關的屬性與用法：

 

網址：http://localhost:1897/News/Press/Content.aspx/123?id=1#toc
Request.ApplicationPath /
Request.PhysicalPath D:\Projects\Solution\web\News\Press\Content.aspx
System.IO.Path.GetDirectoryName(Request.PhysicalPath) D:\Projects\Solution\web\News\Press
Request.PhysicalApplicationPath D:\Projects\Solution\web\
System.IO.Path.GetFileName(Request.PhysicalPath) Content.aspx
Request.CurrentExecutionFilePath /News/Press/Content.aspx
Request.FilePath /News/Press/Content.aspx
Request.Path /News/Press/Content.aspx/123
Request.RawUrl /News/Press/Content.aspx/123?id=1
Request.Url.AbsolutePath /News/Press/Content.aspx/123
Request.Url.AbsoluteUri http://localhost:1897/News/Press/Content.aspx/123?id=1
Request.Url.Scheme http
Request.Url.Host localhost
Request.Url.Port 1897
Request.Url.Authority localhost:1897
Request.Url.LocalPath /News/Press/Content.aspx/123
Request.PathInfo /123
Request.Url.PathAndQuery /News/Press/Content.aspx/123?id=1
Request.Url.Query ?id=1
Request.Url.Fragment  
Request.Url.Segments /
News/
Press/
Content.aspx/
123

 

 

這裡並沒有得到域名的方法.還是隻好拆分字串了,我是這麼做的:

        protected string GetBaseUrl()
        {
            return Request.Url.AbsoluteUri.Substring(0, Request.Url.AbsoluteUri.IndexOf(Request.RawUrl));
        }

       var fullImgUrl = GetBaseUrl() + "/Views/Images.ashx?id=" + map;

 

不知是否有更好的方法得到?
