.Net下修改文件夹或文件的ACL安全权限的类：

SetFolderACL：两个重载函数，设置权限的方法，根据需要选择重载。

GetACL：查看文件夹权限的信息，用户名-权限键值对

GetACLString：查看文件夹权限的文本信息，用户名-权限名键值对

using System;
using System.Collections;
using System.Text;
using System.Security.AccessControl;
using System.IO;

namespace ACL
{
class ACL_FS
{
public static bool SetFolderACL(String FolderPath , String UserName ,
FileSystemRights Rights , AccessControlType AllowOrDeny)
{
InheritanceFlags inherits = InheritanceFlags.ContainerInherit |
InheritanceFlags.ObjectInherit;
return SetFolderACL(FolderPath , UserName , Rights , AllowOrDeny ,
inherits , PropagationFlags.None , AccessControlModification.Add);
}

public static bool SetFolderACL(String FolderPath , String UserName ,
FileSystemRights Rights , AccessControlType AllowOrDeny ,
InheritanceFlags Inherits , PropagationFlags PropagateToChildren ,
AccessControlModification AddResetOrRemove)
{
//过程：获取文件夹安全对象、构造访问规则、修改安全对象的访问规则、重新设置文件夹安全对象
bool ret;
DirectoryInfo folder = new DirectoryInfo(FolderPath);
DirectorySecurity dSecurity = folder.GetAccessControl(AccessControlSections.All);
FileSystemAccessRule accRule = new FileSystemAccessRule(UserName , Rights ,
Inherits , PropagateToChildren , AllowOrDeny);
dSecurity.ModifyAccessRule(AddResetOrRemove , accRule , out ret);
folder.SetAccessControl(dSecurity);
return ret;
}

/// <returns>String,FileSystemRights键值对</returns>
public static Hashtable GetACL(String FolderPath)
{
Hashtable ret = new Hashtable();
DirectorySecurity sec =
Directory.GetAccessControl(FolderPath , AccessControlSections.All);
foreach (FileSystemAccessRule rule in sec.GetAccessRules(true , true ,
typeof(System.Security.Principal.NTAccount)))
{
ret[rule.IdentityReference.ToString()] = rule.FileSystemRights;
}
return ret;
}
public static string GetACLString(String FolderPath)
{
StringBuilder sb = new StringBuilder();
Hashtable rights=GetACL(FolderPath);
foreach (string key in rights.Keys)
{
sb.Append(key + ":/t" + ((FileSystemRights)rights[key]).ToString()+"/r/n");
}
return sb.ToString();
}

}
}
//以上在WindowsXP、Windows Server 2003下测试通过。
