如何用代码实现对有用户名和密码的服务器的连接

[spacerain]

问题是这样的:bs结构，在客户端用浏览器访问服务器上的一个共享文件夹时，总是需要先在客户机上先连通服务器，即：通过“开始”--〉运行--〉\\10.10.108.11--〉输入用户名和密码，然后才能通过浏览器访问服务器的共享文件夹。请问有没有什么办法直接在程序里通过代码来完成对服务器的登陆呢。多谢多谢!~!~!~

Process app=new Process();
string netCMD=" use \\\\10.10.131.252"+"\\ReportFile "+" 3553 /user:administrator";
ProcessStartInfo info=new ProcessStartInfo(@"net",netCMD);
info.RedirectStandardError=true;
info.RedirectStandardOutput=true;
info.UseShellExecute=false;
info.CreateNoWindow = true;
app.StartInfo=info;
app.Start();
app.WaitForExit();

请问为什么执行到app.Start(); 时会捕捉到"拒绝访问"的错误呢,两位高手请指教.

可怜你,高手太多,可是出手的为什么总是我们这些不懂的呢???

Process p;
p=new Process();
p.StartInfo.FileName="cmd.exe";

// 这里是关键点,不用Shell启动/重定向输入/重定向输出/不显示窗口
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.CreateNoWindow = true;

p.Start();
// p.StandardInput.WriteLine("net use " + server + " " + pass + " /user:" + user);// 向cmd.exe输入command
p.StandardInput.WriteLine("net use \\\\192.168.0.1 Com#work /user:Administrator");// 向cmd.exe输入command
p.StandardInput.WriteLine("exit");
p.WaitForExit();
// string s = p.StandardOutput.ReadToEnd();// 得到cmd.exe的输出
p.Close();

上次不记得是哪位好心人给了我代码？发给你吧？
net　use的就免了吧。
是API的，我也看不懂。你慢慢的改吧？

怎么木有人帮帮我呀，请大家帮个忙:)

先把动态的IP用域名解析出来,然后登陆定向与目录下,就行了

用Process和命令行net use命令结合起来实现
