C#访问带密码的网络路径

Question

想访问网上邻居，路径是"\\192.168.0.22\Mydata".
例如：
 File.Copy(@"\\192.168.0.22\Mydata\test.txt", desFilePath);
由于访问\\192.168.0.22\Mydata需要用户名和密码，所以执行上述代码的时候目标路径拒绝访问。
请问如何在代码中输入用户名和密码。

    } 我是这样做的，但是不行，执行 AccessFile（string remoteName）   方法里CopyFileByNet.WNetAddConnection2(ref   nr, "pwd", "usrName", ConnectionOption.CONNECT_INTERACTIVE)的不成功

Answer 4

好吧，我好像把 ftp 的用法和共享搞混了

Answer 5

执行CopyFileByNet.WNetAddConnection2(ref nr, "pwd", "usrName", ConnectionOption.CONNECT_INTERACTIVE)这句后，返回值是ERROR_BAD_DEVICE

Answer 6

Process.Start( "cmd.exe ",   "/k   Net   Use   \\192.168.0.110\d$\share   密码   /user:用户 ") 

Answer 7

1，net use命令
2，WnetAddConnection2 API
