C#读写共享文件夹的方法
本文实例为大家分享了C#读写共享文件夹的具体代码，供大家参考，具体内容如下
该试验分以下步骤：
1、在服务器设置一个共享文件夹，在这里我的服务器ip地址是10.80.88.180，共享文件夹名字是test，test里面有两个文件：good.txt和bad.txt，访问权限，用户名是admin，密码是admin。
2、新建一个webapplication项目，在前台页面加一个listbox，ID是ListBox1.
3、添加后台代码如下：其中包含的功能是读文件，这里以读good文件为例；写文件，这里以写bad文件为例；还有是将test文件夹下的文件名列到listbox中。
