如何从Web服务器C#Web应用程序获取本地计算机文件路径

我正在开发一个Web应用程序，我想在其中列出本地计算机上的文件，例如d:\ Trial Folder

实际上，所有将要使用我的Web应用程序的用户都将在其本地驱动器"D:\"冒号上拥有Trial文件夹，即每个用户都将拥有d:\ Trial文件夹

现在，当用户登录时，我想向他显示d:\ Trial文件夹中的所有文件列表.

但我不知道如何获取本地机器路径

我使用了System.IO的代理，但是我没有得到下面的文件，这是我的示例代码

请帮帮我

i am developing a web application in which i want to list out the files on local computers lets say d:\Trial Folder

actually all the user who is going to use my web application will have Trial folder on their local drive "D:\" colon i.e. each user will have d:\Trial Folder

now when user login then i want to show him the all file list from d:\Trial folder to him.

but i dont know how to get the local machine path

i used System.IO''s deiectory but i am not getting the file below is my sample code

string dipath=@"d:\\Trial\\";
string[] dirs = Directory.GetFiles(dipath);
foreach (string dir in dirs)
