在两台不同的机器上使用 Microsoft Sync Framework 时无法同步网络上的文件

Question

我正在尝试在网络上使用 MS 同步框架。但它给了我一个例外找不到路径的一部分。谁能告诉我如何在网络上建立连接，以便通过网络同步不同计算机上的两个文件夹。 我可以从我的资源管理器中访问该文件夹，因此共享或权限没有问题。我在同一个wifi网络中。我有一个线索，也许我必须以某种方式输入凭据。

 private void button1_Click(object sender, EventArgs e)
        {
     
           FileSyncProvider sourceReplica = new FileSyncProvider(Guid.NewGuid(), @"E:\test");
            FileSyncProvider destReplica = new FileSyncProvider(Guid.NewGuid(), @"\\192.168.1.9\New Folder"); //Here I am getting exception.
  
            SyncOrchestrator agent = new SyncOrchestrator();
            agent.LocalProvider = sourceReplica;
            agent.RemoteProvider = destReplica;
            agent.Direction = SyncDirectionOrder.UploadAndDownload;
            agent.Synchronize();

        }

Answer 1

所以在花了很多时间之后，我终于找到了一个解决方案。实际上问题出在凭据上。所以我在网上研究并找到了解决方案。

我从类似这样的答案中复制了一个文件。

namespace syncDemo
{
    class ConnectToSharedFolder :IDisposable
    {
        readonly string _networkName;

        public ConnectToSharedFolder(string networkName, NetworkCredential credentials)
        {
            _networkName = networkName;

            var netResource = new NetResource
            {
                Scope = ResourceScope.GlobalNetwork,
                ResourceType = ResourceType.Disk,
                DisplayType = ResourceDisplaytype.Share,
                RemoteName = networkName
            };

            var userName = string.IsNullOrEmpty(credentials.Domain)
                ? credentials.UserName
                : string.Format(@"{0}\{1}", credentials.Domain, credentials.UserName);

            var result = WNetAddConnection2(
                netResource,
                credentials.Password,
                userName,
                0);

            if (result != 0)
            {
                throw new Win32Exception(result, "Error connecting to remote share");
            }
        }

        ~ConnectToSharedFolder()
        {
            Dispose(false);
        }

        public void Dispose()
        {
            Dispose(true);
            GC.SuppressFinalize(this);
        }

        protected virtual void Dispose(bool disposing)
        {
            WNetCancelConnection2(_networkName, 0, true);
        }

        [DllImport("mpr.dll")]
        private static extern int WNetAddConnection2(NetResource netResource,
            string password, string username, int flags);

        [DllImport("mpr.dll")]
        private static extern int WNetCancelConnection2(string name, int flags,
            bool force);

        [StructLayout(LayoutKind.Sequential)]
        public class NetResource
        {
            public ResourceScope Scope;
            public ResourceType ResourceType;
            public ResourceDisplaytype DisplayType;
            public int Usage;
            public string LocalName;
            public string RemoteName;
            public string Comment;
            public string Provider;
        }

        public enum ResourceScope : int
        {
            Connected = 1,
            GlobalNetwork,
            Remembered,
            Recent,
            Context
        };

        public enum ResourceType : int
        {
            Any = 0,
            Disk = 1,
            Print = 2,
            Reserved = 8,
        }

        public enum ResourceDisplaytype : int
        {
            Generic = 0x0,
            Domain = 0x01,
            Server = 0x02,
            Share = 0x03,
            File = 0x04,
            Group = 0x05,
            Network = 0x06,
            Root = 0x07,
            Shareadmin = 0x08,
            Directory = 0x09,
            Tree = 0x0a,
            Ndscontainer = 0x0b
        }
    }
}

在我的主要形式中，我这样做了。

public string networkPath = @"\\{I.P}\New Folder";
        NetworkCredential credentials = new NetworkCredential(@"userName", "password");

private void button1_Click(object sender, EventArgs e)
        {

            FileSyncProvider sourceReplica = new FileSyncProvider(Guid.NewGuid(), @"E:\test");
            FileSyncProvider destReplica;
            using (new ConnectToSharedFolder(networkPath, credentials))
            {
               destReplica = new FileSyncProvider(Guid.NewGuid(), @"\\192.168.1.9\New Folder");
            }
            
            SyncOrchestrator agent = new SyncOrchestrator();
            agent.LocalProvider = sourceReplica;
            agent.RemoteProvider = destReplica;
            agent.Direction = SyncDirectionOrder.UploadAndDownload;
            agent.Synchronize();

        }
