C#设置与获取目录权限(.net控制ACL)

找到两种方式可以修改文件夹的权限

第一种:

想用c#来设置和读取ntfs分区上的目录权限,找了很多资料,未果。终于发现了一段vb.net的代码,做了修改,以C#展示给大家。

using System;
using System.Collections;
using System.IO;
using System.Security.AccessControl;
static class Tester
{

    public static void Main()
    {
        try
        {
            string filename = @"f:\k"//目标目录
            string account = @"Administrator";//用户名
            string userrights = @"RW";//权限字符串,自己定义的
            AddDirectorySecurity(filename, account, userrights);
            Console.ReadLine();
        }
        catch (Exception e)
        {
            Console.WriteLine(e);
            Console.ReadLine();
        }
    }

    static public void AddDirectorySecurity(string FileName, string Account, string UserRights)
    {
        FileSystemRights Rights = new FileSystemRights();

        if (UserRights.IndexOf("R">= 0)
        {
            Rights = Rights | FileSystemRights.Read;
        }
        if (UserRights.IndexOf("C">= 0)
        {
            Rights = Rights | FileSystemRights.ChangePermissions;
        }
        if (UserRights.IndexOf("F">= 0)
        {
            Rights = Rights | FileSystemRights.FullControl;
        }
        if (UserRights.IndexOf("W">= 0)
        {
            Rights = Rights | FileSystemRights.Write;
        }

        bool ok;
        DirectoryInfo dInfo = new DirectoryInfo(FileName);
        DirectorySecurity dSecurity = dInfo.GetAccessControl();
        InheritanceFlags iFlags = new InheritanceFlags();
        iFlags = InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit;
        FileSystemAccessRule AccessRule2 = new FileSystemAccessRule(Account, Rights, iFlags, PropagationFlags.None, AccessControlType.Allow);
        dSecurity.ModifyAccessRule(AccessControlModification.Add, AccessRule2, out ok);

        dInfo.SetAccessControl(dSecurity);

        //列出目标目录所具有的权限
        DirectorySecurity sec = Directory.GetAccessControl(FileName, AccessControlSections.All);
        foreach (FileSystemAccessRule rule in sec.GetAccessRules(truetruetypeof(System.Security.Principal.NTAccount)))
        {
            Console.WriteLine("----------------------------------");             Console.WriteLine(rule.IdentityReference.Value);             if ((rule.FileSystemRights & FileSystemRights.Read) != 0)                 Console.WriteLine(rule.FileSystemRights.ToString());         }         Console.Read();     } }



对照MSDN,很容易看懂上面的代码。 但是貌似这个程序需要以管理员身份来运行。^_^

其中的Directory.GetAccessControl(FileName, AccessControlSections.All);  第二个参数如果为AccessControlSections.Access ,就可以使得运行在IIS中的Web应用程序获得目录权限了。

第二种方法:该方法就不多说了,搜索大多博客都写了第二种方法来设置权限,但是,实际上这种方法根本无法给目录设置用户权限(测试多次无法设置成功,不知其他人是否成功设置),

        /// <summary>
        /// 目录权限
        /// </summary>
        public enum FloderRights
        {
            FullControl,
            Read,
            Write
        }
        public static void AddPathRights(string pathname, string username, FloderRights qx)
        {

            //FileInfo fi = new FileInfo(pathname);
            //System.Security.AccessControl.FileSecurity fileSecurity = fi.GetAccessControl();
            //fileSecurity.AddAccessRule(new FileSystemAccessRule("Everyone", FileSystemRights.FullControl, AccessControlType.Allow));
            //fileSecurity.AddAccessRule(new FileSystemAccessRule("Users", FileSystemRights.FullControl, AccessControlType.Allow));
            //fi.SetAccessControl(fileSecurity);


            DirectoryInfo dirinfo = new DirectoryInfo(Path.GetDirectoryName(pathname));
            if ((dirinfo.Attributes & FileAttributes.ReadOnly) != 0)
            {
                dirinfo.Attributes = FileAttributes.Normal;
            }
            //取得访问控制列表
            DirectorySecurity dirsecurity = dirinfo.GetAccessControl();
            // string strDomain = Dns.GetHostName();
            //System.Security.AccessControl.DirectorySecurity dirsecurity = dirinfo.GetAccessControl();
            switch (qx)
            {
                case FloderRights.FullControl:
                    dirsecurity.AddAccessRule(new FileSystemAccessRule(username, FileSystemRights.FullControl, AccessControlType.Allow));
                    break;
                case FloderRights.Read:
                    dirsecurity.AddAccessRule(new FileSystemAccessRule(username, FileSystemRights.Read, AccessControlType.Allow));
                    break;
                case FloderRights.Write:
                    dirsecurity.AddAccessRule(new FileSystemAccessRule(username, FileSystemRights.Write, AccessControlType.Allow));
                    break;
                default:
                    dirsecurity.AddAccessRule(new FileSystemAccessRule(username, FileSystemRights.FullControl, AccessControlType.Allow));
                    break;
            }
            dirinfo.SetAccessControl(dirsecurity);
            //System.IO.Directory.SetAccessControl(pathname, dirsecurity);

            //取消目录从父继承
            //DirectorySecurity dirSecurity = System.IO.Directory.GetAccessControl(pathname);
            //dirSecurity.SetAccessRuleProtection(true, false);
            //System.IO.Directory.SetAccessControl(pathname, dirSecurity);

            //AccessControlType.Allow允许访问受保护对象//Deny拒绝访问受保护对象
            //FullControl、Read 和 Write 完全控制,读,写
            //FileSystemRights.Write写入//Delete删除 //DeleteSubdirectoriesAndFiles删除文件夹和文件//ListDirectory读取
            //Modify读写删除-修改//只读打开文件和复制//
        }
