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.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(true, true, typeof(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//
