C# 读写网上邻居中的共享文件

读写网上邻居共享的文件夹，和操作本地文件夹类似，只要有权限读取写入即可。

分为以下2步：

1.打通共享文件夹权限

2.操作文件

 

 

打通共享文件夹权限

 2         /// 连接共享文件
 3         /// </summary>

 5         /// <param name="username">用户名</param>
 6         /// <param name="password">密码</param>
 7         /// <returns>true:连接成功 false:连接失败</returns>
 8         public static bool connectstate(string path, string username, string password)
 9         {
10             bool flag = false;
11             process proc = new process();
12             try
13             {
14                 proc.startinfo.filename = "cmd.exe";

22                 proc.standardinput.writeline(dosline);
23                 proc.standardinput.writeline("exit");
24                 while (!proc.hasexited)
25                 {

29                 proc.standarderror.close();
30                 if (string.isnullorempty(errormsg))
31                 {
32                     flag = true;
33                 }
34                 else
35                 {
36                     throw new exception(errormsg);
37                 }
38             }
39             catch (exception ex)
40             {
41                 throw ex;
42             }
43             finally
44             {
45                 proc.close();
46                 proc.dispose();
47             }
48 
49             return flag;
50         }

创建文件夹

 

1 directoryinfo dirinfo = new directoryinfo("\\win-r3377jmr1lg\sharefolder");
2 if (dirinfo.exists == false)
3 {
4     dirinfo.create();
5 }

上传文件
