如何利用网页的形式访问服务器的共享文件夹，并获取文件夹内容列表

Question

如题

Answer 1

列出子文件夹
此示例代码使用 Directory 类的 GetDirectories 方法获取文件夹列表。     string[] dirs = Directory.GetDirectories(winDir);
    foreach(string dir in dirs)
        {
            addListItem(dir);
        }列出文件
此示例使用 Directory 类的 GetFiles 方法获取文件夹列表。     string[] files= Directory.GetFiles(winDir);
    foreach (string i in files)
    {
        addListItem(i);
    }

Answer 2

必须包括 System.IO 命名空间，如下所示：using System.IO;
 
• 按如下方式声明 winDir 变量：string    winDir=System.Environment.GetEnvironmentVariable("windir");
 
• 按如下方式声明 addListItem 函数：private void addListItem(string value)
{
this.listbox1.Items.Add(value);
}

注意：可以直接使用下列语句，而不用声明和使用 addListItem 函数： this.listbox1.Items.Add(value);"

Answer 6

首先，谢谢singlepine(小山)，你提供给我一种利用winform的形式访问本地文件夹的方法。
但我还想知道如何利用网页的形式去访问远程服务器的文件夹 的方法！

Answer 7

远程服务器的文件夹要明确他的绝对路径或者本站点内的相对路径,并且还得有用户的访问权限(user用户等)
