问题描述：
使用如下代码：
DirectorySecurity fSec = new DirectorySecurity();
fSec.AddAccessRule(new FileSystemAccessRule(@"Everyone", FileSystemRights.FullControl, AccessControlType.Allow));
System.IO.Directory.SetAccessControl(FolderPath, fSec);
控制文件夹权限，本应该为完全控制，但结果只显示特殊权限。
文件夹的特殊权限表示，子文件和文件夹的权限不一致导致。因此代码做如下修改
/// <summary>
/// 设置文件夹的ACL
/// </summary>
/// <param name="folderPath">文件夹路径</param>
/// <param name="userName">用户</param>
/// <param name="rights">权限</param>
/// <param name="allowOrDeny">拒绝访问</param>
/// <returns></returns>
public static bool SetFolderACL(
string folderPath,
string userName,
FileSystemRights rights,
AccessControlType allowOrDeny)
{
//设定文件ACL继承
InheritanceFlags inherits = InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit;
return SetFolderACL(folderPath, userName, rights, allowOrDeny, inherits, PropagationFlags.None, AccessControlModification.Add);
}
/// <summary>
/// 设置文件夹的ACL
/// </summary>
/// <param name="folderPath">文件夹路径</param>
/// <param name="userName">用户</param>
/// <param name="rights">权限</param>
/// <param name="allowOrDeny">拒绝访问</param>
/// <param name="inherits">ACL继承</param>
/// <param name="propagateToChildren">应用于子文件夹及子文件</param>
/// <param name="addResetOrRemove">修改类型</param>
/// <returns></returns>
public static bool SetFolderACL(
string folderPath,
string userName,
FileSystemRights rights,
AccessControlType allowOrDeny,
InheritanceFlags inherits,
PropagationFlags propagateToChildren,
AccessControlModification addResetOrRemove)
{
bool result;
//获取目录信息
var folder = new DirectoryInfo(folderPath);
//获取当前文件夹ACL
var dSecurity = folder.GetAccessControl(AccessControlSections.All);
//设置新的ACL规则
var accRule = new FileSystemAccessRule(userName, rights, inherits, propagateToChildren, allowOrDeny);
//修改文件夹ACL
dSecurity.ModifyAccessRule(addResetOrRemove, accRule, out result);
//应用新的ACL规则到文件夹
folder.SetAccessControl(dSecurity);
//返回结果
return result;
}
