菜鸟问题-如何将文件上传至另一台机器的共享文件夹

[倒霉熊]

如题，两台机器都在同一个域，因为网站服务器不能存放临时文件，所以在工作中要将临时文件存放在另一台机器的共享文件夹中，可以提供下载。可以在那个共享文件夹中新建文件夹。那个文件夹只给一个用户开了权限，小弟没有做过类似的东东，请大家帮忙给个思路。

表述的不清楚，欢迎大家再次提问，在线等。

我的测试代码，没有问题。。。。。

public static void TestNetWorkConnection()
        {
            string localpath = "X:";
            int status = NetworkConnection.Connect("\\\\192.168.0.21\\安装备份", localpath, @"administrator", "Admin");
            if (status == (int)ERROR_ID.ERROR_SUCCESS)
            {
                FileStream fs = new FileStream(localpath + @"\\123.txt", FileMode.OpenOrCreate);
                using (StreamWriter stream = new StreamWriter(fs))
                {
                    stream.WriteLine("你好呀，成功了");
                    stream.Flush();
                    stream.Close();
                }
                fs.Close();
            }
            else
            {
                Console.WriteLine(status);
            }
            NetworkConnection.Disconnect(localpath);
        }

还是1200，哎

[倒霉熊]

 public static bool connectState(string path, string userName, string passWord)
        {
            bool Flag = false;
            Process proc = new Process();
            try
            {
                proc.StartInfo.FileName = "cmd.exe";
                proc.StartInfo.UseShellExecute = false;
                proc.StartInfo.RedirectStandardInput = true;
                proc.StartInfo.RedirectStandardOutput = true;
                proc.StartInfo.RedirectStandardError = true;
                proc.StartInfo.CreateNoWindow = true;
                proc.Start();
                string dosLine = @"net use " + path + " /User:" + userName + " " + passWord + " /PERSISTENT:YES";
                proc.StandardInput.WriteLine(dosLine);
                proc.StandardInput.WriteLine("exit");
                while (!proc.HasExited)
                {
                    proc.WaitForExit(1000);
                }
                string errormsg = proc.StandardError.ReadToEnd();

                proc.StandardError.Close();

                if (string.IsNullOrEmpty(errormsg))
                {
                    Flag = true;
                }
                else
                {
                    throw new Exception(errormsg);
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }
            finally
            {
                proc.Close();
                proc.Dispose();
            }
            return Flag;
        }
    }

这段代码，网上找的，报：提供的用户上下文无效。头疼死了。

解决啦

[lnit728]

如果已经开通了共享，你直接在你的电脑上 开始 --》运行---》输入你要访问的文件夹地址就可以了 (\\192.168.0...\...）

[倒霉熊]

我想用C#代码实现...

[isjoe]

C#实现访问网络共享文件夹，使用 WNetAddConnection2A 和 WNetCancelConnection2A。

在目标服务器建立共享文件夹，建立访问账号test;

public enum ERROR_ID
    {
        ERROR_SUCCESS = 0,  // Success 
        ERROR_BUSY = 170,
        ERROR_MORE_DATA = 234,

        ERROR_ACCESS_DENIED = 5,
        ERROR_INVALID_PASSWORD = 86,
        ERROR_INVALID_PARAMETER = 87,
        ERROR_BAD_DEV_TYPE = 66,

        ERROR_DEVICE_ALREADY_REMEMBERED = 1202,
        ERROR_NO_NET_OR_BAD_PATH = 1203
    }

    public enum RESOURCE_SCOPE
    {
        RESOURCE_CONNECTED = 1,
        RESOURCE_GLOBALNET = 2,
        RESOURCE_REMEMBERED = 3,
        RESOURCE_RECENT = 4,
        RESOURCE_CONTEXT = 5
    }

    public enum RESOURCE_TYPE

    [StructLayout(LayoutKind.Sequential)]
    public struct NETRESOURCE
    {

        public RESOURCE_DISPLAYTYPE dwDisplayType;
        public RESOURCE_USAGE dwUsage;

        [MarshalAs(UnmanagedType.LPStr)]
        public string lpLocalName;

        [MarshalAs(UnmanagedType.LPStr)]
        public string lpRemoteName;

        [MarshalAs(UnmanagedType.LPStr)]
        public string lpComment;

    }

    public class NetworkConnection
    {

        [DllImport("mpr.dll")]
        public static extern int WNetAddConnection2A (NETRESOURCE[] lpNetResource, string lpPassword, string lpUserName, int dwFlags);

        [DllImport("mpr.dll")]
        public static extern int WNetCancelConnection2A (string sharename, int dwFlags, int fForce);


        public static int Connect (string remotePath, string localPath, string username, string password)
        {
            NETRESOURCE[] share_driver = new NETRESOURCE[1];
            share_driver[0].dwScope = RESOURCE_SCOPE.RESOURCE_GLOBALNET;
            share_driver[0].dwType = RESOURCE_TYPE.RESOURCETYPE_DISK;
            share_driver[0].dwDisplayType = RESOURCE_DISPLAYTYPE.RESOURCEDISPLAYTYPE_SHARE;

            Disconnect(localPath);
            int ret = WNetAddConnection2A(share_driver, password, username, 1);

            return ret;
        }

        public static int Disconnect (string localpath)
        {
            return WNetCancelConnection2A(localpath, 1, 1);
        }

 调用方式：

public static void TestNetWorkConnection()
        {
            string localpath = "X:";
            //int status = NetworkConnection.Connect(@"\\192.168.0.2\test", localpath, @"test", "test");
            int status = NetworkConnection.Connect("\\\\192.168.0.2\\test", localpath, @"test", "test");
            if (status == (int)ERROR_ID.ERROR_SUCCESS)
            {
                FileStream fs = new FileStream(localpath + @"\\123.txt", FileMode.OpenOrCreate);
                using (StreamWriter stream = new StreamWriter(fs))
                {
                    stream.WriteLine("你好呀，成功了");
                    stream.Flush();
                    stream.Close();
                }
                fs.Close();
            }
            else
            {
                Console.WriteLine(status);
            }
            NetworkConnection.Disconnect(localpath);
        }

[倒霉熊]

不行呀，返回1200 不知道什么意思。

[yuanjia1985213]

将文件上传至另一台机器的共享文件夹你是咋么实现的?请指教

[qiuuan526]

WNetAddConnection2A 一直返回67 ，不知道为什么？？请教大家 谢谢

后来用WebService做的，不然别的方法不安全
