使用共享计算机的本地凭据访问共享文件夹

Question

我正在尝试使用来自另一台机器B的凭据“machineA\user”访问共享文件夹“\machineA\shared”。不幸的是，machineA 不在 machineB 的域中。我怎样才能通过c#访问共享文件夹....

尝试使用此代码不起作用

NetworkCredential theNetworkCredential = new NetworkCredential(equipment.User, equipment.Password);
CredentialCache theNetCache = new CredentialCache();
theNetCache.Add(new Uri(equipment.SourceFolder), "Basic", theNetworkCredential);
string[] theFiles1 = Directory.GetFiles(equipment.SourceFolder);

Note：此问题总结整理于: Access a shared folder using the shared machine's local credential

由于 machineA 不在 machineB 的域中，因此您可以使用mpr.dll添加远程网络连接。 下面是一个你可能需要的示例：

        public static class WNetConnectionHelper  
        {  
            [DllImport("mpr.dll", EntryPoint = "WNetAddConnection2")]  
            private static extern uint WNetAddConnection2(NetResource lpNetResource, string lpPassword, string lpUsername, uint dwFlags);  
  
            [DllImport("Mpr.dll", EntryPoint = "WNetCancelConnection2"))]  
            private static extern uint WNetCancelConnection2(string lpName, uint dwFlags, bool fForce);  
  
            [StructLayout(LayoutKind.Sequential)]  
            public class NetResource  
            {  
                public int dwScope;  
                public int dwType;  
                public int dwDisplayType;  
                public int dwUsage;  
                public string lpLocalName;  
                public string lpRemoteName;  
                public string lpComment;  
                public string lpProvider;  
            }  
  
            public static uint WNetAddConnection(NetResource netResource, string username, string password)  
            {  
                uint result = WNetAddConnection2(netResource, password, username, 0);  
                return result;  
            }  
  
            public static uint WNetAddConnection(string username, string password, string remoteName, string localName)  
            {  
                NetResource netResource = new NetResource();  
                netResource.dwScope = 2;       //RESOURCE_GLOBALNET  
                netResource.dwType = 1;       //RESOURCETYPE_ANY  
                netResource.dwDisplayType = 3; //RESOURCEDISPLAYTYPE_GENERIC  
                netResource.dwUsage = 1;       //RESOURCEUSAGE_CONNECTABLE  
                netResource.lpLocalName = localName;  
                netResource.lpRemoteName = remoteName.TrimEnd('/');  
  
                uint result = WNetAddConnection2(netResource, password, username, 0);  
                return result;  
            }  
  
            public static uint WNetCancelConnection(string name, uint flags, bool force)  
            {  
                uint nret = WNetCancelConnection2(name, flags, force);  
                return nret;  
            }  
        }  

这是另一种可能有帮助的解决方案。
