请问c# 怎么设置系统文件夹及子文件夹的共享？
问题
-
需求是winform程序中创建一个文件夹，并设置为共享（所有子文件夹和子文件都要共享），设置everyone有fullcontrol的权限，其他人连接进来可以操作。（操作系统不能确定，可能是win7也可能是server2003/2008等）
试了几种方式，都有问题。我把几种情况列举下，语言组织不好，不好意思。
问题一：共享只能共享根文件夹，打开共享内的文件提示 拒绝访问。我试着递归循环里面所有的文件夹并设置共享，但是文件夹内的文件依然拒绝访问。而且后期程序会生成大量文件夹和文件在里面，生成一个文件夹就设置一次共享肯定不行。
问题二：根文件夹都共享不成功，拒绝访问。看了下文件夹属性-安全-组或用户名 里面用户没有everyone。然后我在程序里面先添加该文件夹everyone的操作权限fullcontrol，但是出来的效果却是特殊权限。依然不能解决问题。
下面是几种共享的代码：（我对这些不懂，都是查的，希望大神们指点一下）
第一种：
// Create a ManagementClass object ManagementClass managementClass = new ManagementClass("Win32_Share"); // Create ManagementBaseObjects for in and out parameters ManagementBaseObject inParams = managementClass.GetMethodParameters("Create"); ManagementBaseObject outParams; // Set the input parameters inParams["Description"] = Description; inParams["Name"] = ShareName; inParams["Path"] = FolderPath; inParams["Type"] = 0x0; // Disk Drive //inParams["Access"] = null; //null = 使Everyone拥有完全控制权限 //Another Type: // DISK_DRIVE = 0x0 // PRINT_QUEUE = 0x1 // DEVICE = 0x2 // IPC = 0x3 // DISK_DRIVE_ADMIN = 0x80000000 // PRINT_QUEUE_ADMIN = 0x80000001 // DEVICE_ADMIN = 0x80000002 // IPC_ADMIN = 0x8000003 //inParams["MaximumAllowed"] = int maxConnectionsNum; // Invoke the method on the ManagementClass object outParams = managementClass.InvokeMethod("Create", inParams, null); // Check to see if the method invocation was successful if ((uint)(outParams.Properties["ReturnValue"].Value) != 0) { throw new Exception("共享失败"); }第二种：
CommandSilentExecution cmd = new CommandSilentExecution(); //cmd.RunCmd(" cacls " + FolderPath + " /g everyone:f net share " + ShareName + "=" + FolderPath + " /grant:everyone,full"); //cmd.RunCmd("net share " + ShareName + "=" + FolderPath + ""); cmd.RunCmd("net share " + ShareName + "=" + FolderPath + " /grant:everyone,full"); public void RunCmd(string cmd) { proc.StartInfo.CreateNoWindow = true; proc.StartInfo.FileName = "cmd.exe"; proc.StartInfo.UseShellExecute = false; proc.StartInfo.RedirectStandardError = true; proc.StartInfo.RedirectStandardInput = true; proc.StartInfo.RedirectStandardOutput = true; proc.Start(); proc.StandardInput.WriteLine(cmd); proc.Close(); }
第三种：

设置文件夹操作权限：
private static void AddpathFilePower(string pathname, string username, string power) { try { FileInfo dirinfo = new FileInfo(pathname); if ((dirinfo.Attributes & FileAttributes.ReadOnly) != 0) { dirinfo.Attributes = FileAttributes.Normal; } //取得访问控制列表 FileSecurity dirsecurity = dirinfo.GetAccessControl(); switch (power) { case "FullControl": //dirsecurity.AddAccessRule(new FileSystemAccessRule(username, FileSystemRights.FullControl, InheritanceFlags.ContainerInherit, PropagationFlags.InheritOnly, AccessControlType.Allow)); //dirsecurity.AddAccessRule(new FileSystemAccessRule(username, FileSystemRights.FullControl,AccessControlType.Allow)); dirsecurity.AddAccessRule(new FileSystemAccessRule(username, FileSystemRights.FullControl, AccessControlType.Allow)); break; case "ReadOnly": dirsecurity.AddAccessRule(new FileSystemAccessRule(username, FileSystemRights.Read, AccessControlType.Allow)); break; case "Write": dirsecurity.AddAccessRule(new FileSystemAccessRule(username, FileSystemRights.Write, AccessControlType.Allow)); break; case "Modify": dirsecurity.AddAccessRule(new FileSystemAccessRule(username, FileSystemRights.Modify, AccessControlType.Allow)); break; } dirinfo.SetAccessControl(dirsecurity); } catch (Exception) { throw; } }

Hi,
你使用了下面的代码吗？ 可以参考一下
DirectoryInfo info = new DirectoryInfo(path[x]); DirectorySecurity security = info.GetAccessControl(); security.AddAccessRule(new FileSystemAccessRule(logonName, FileSystemRights.Modify, InheritanceFlags.ContainerInherit, PropagationFlags.None, AccessControlType.Allow)); security.AddAccessRule(new FileSystemAccessRule(logonName, FileSystemRights.Modify, InheritanceFlags.ObjectInherit, PropagationFlags.None, AccessControlType.Allow)); info.SetAccessControl(security);
你可以提供一个demo给我们吗? 这样方便测试

你有debug的代码吗？第二部分代码有没有执行成功？这段代码写了，就是我传的最后一段。
demo我中午弄吧
