asp.net 各种路径查找

记性不好,好多次都被路径问题给拦住了.我现在想得到一个资源的全URL路径,因此首先想得到网站当前的域名,端口和虚拟目录.看下表

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:ProjectsSolutionwebNewsPressContent.aspx
System.IO.Path.GetDirectoryName(Request.PhysicalPath) D:ProjectsSolutionwebNewsPress
Request.PhysicalApplicationPath D:ProjectsSolutionweb
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
// 获取程序的基目录。
System.AppDomain.CurrentDomain.BaseDirectory
 
// 获取模块的完整路径。
System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName
 
// 获取和设置当前目录(该进程从中启动的目录)的完全限定目录。
System.Environment.CurrentDirectory
 
// 获取应用程序的当前工作目录。
System.IO.Directory.GetCurrentDirectory() 

// 获取和设置包括该应用程序的目录的名称。
System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase
 
// 获取启动了应用程序的可执行文件的路径。
System.Windows.Forms.Application.StartupPath 

// 获取启动了应用程序的可执行文件的路径及文件名
System.Windows.Forms.Application.ExecutablePath
 
 
 
C# WinForm中AppDomain.CurrentDomain.BaseDirectory与Application.StartupPath的区别示例如下:
 
private void Frm_Server_Load(object sender, EventArgs e)
        {
            MessageBox.Show(AppDomain.CurrentDomain.BaseDirectory);
            MessageBox.Show(Application.StartupPath );
         }
 
说明:
 
1.   AppDomain.CurrentDomain.BaseDirectory 返回结果为: D:mycode
 
     Application.StartupPath 返回结果为: D:mycode
 
2.  Application.StartupPath 只能用于WinForm窗体中,而AppDomain.CurrentDomain.BaseDirectory既可以用于WinForm窗体中,也可以用于类库DLL文件中.
3. HttpContext.Current.Request.Url.Host.ToString() 返回结果为:http://locahost.XXXX.XXX
   HttpContext.Current.Server.MapPath();
   System.Web.HttpContext.Current.Request.PhysicalApplicationPath
