在Windows编程中，我们通常需要借助通用对话框的力量，今天我们就聊一下“安全属性表”通用对话框的使用心得。
当我们调用EditSecurity函数时：
1.EditSecurity将调用ISecurityInformation中的GetObjectInformation函数
在编写 ISecurityInformation.GetObjectInformation(out SI_OBJECT_INFO pObjectInfo)时
我们需要将结构返还给函数，GetObjectInformation用于初始化属性表的样式
看一下结构：
public struct SI_OBJECT_INFO
{
public uint dwFlags;
public IntPtr hInstance;
public string pszServerName;
public string pszObjectName;
public string pszPageTitle;
public Guid guidObjectType;
}
解释一下：dwFlags为属性表样式的标志SI_OBJECT_INFO 结构
pszObjectName为属性表的标题
pszPageTitle为属性页的标题
2.接着EditSecurity将调用ISecurityInformation中的GetSecurity函数
GetSecurity(uint RequestedInformation, out IntPtr ppSecurityDescriptor, bool fDefault)
其他我们不需要过于处理，专注于“ppSecurityDescriptor”，一个句柄，
例如：
public string _filePath;
public void GetSecurity(uint RequestedInformation, out IntPtr ppSecurityDescriptor, bool fDefault)
{
ppSecurityDescriptor = IntPtr.Zero;
// 获取文件的安全描述符
var fileSecurity = File.GetAccessControl(_filePath);
var rawSecurityDescriptor = fileSecurity.GetSecurityDescriptorBinaryForm();
// 将安全描述符复制到非托管内存
ppSecurityDescriptor = Marshal.AllocHGlobal(rawSecurityDescriptor.Length);
Marshal.Copy(rawSecurityDescriptor, 0, ppSecurityDescriptor, rawSecurityDescriptor.Length);
}
3.当我们将这两个函数处理好以后基本就可以弹出这个对话框了
如下（Powershell+C#）：
Add-Type -TypeDefinition @"
using System;
using System.IO;
using System.Runtime.InteropServices;
// 定义必要的结构和接口
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)]public struct SI_OBJECT_INFO{public uint dwFlags;public IntPtr hInstance;public string pszServerName;public string pszObjectName;public string pszPageTitle;public Guid guidObjectType;}[ComImport, Guid("965FC360-16FF-11d0-91CB-00AA00BBB723"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]public interface ISecurityInformation{void GetObjectInformation(out SI_OBJECT_INFO pObjectInfo);void GetSecurity(uint RequestedInformation, out IntPtr ppSecurityDescriptor, [MarshalAs(UnmanagedType.Bool)] bool fDefault);void SetSecurity(uint SecurityInformation, IntPtr pSecurityDescriptor);void GetAccessRights(ref Guid pguidObjectType, uint dwFlags, out IntPtr ppAccess, out uint pcAccesses, out uint piDefaultAccess);void MapGeneric(ref Guid pguidObjectType, ref byte pAceFlags, ref uint pMask);void GetInheritTypes(out IntPtr ppInheritTypes, out uint pcInheritTypes);void PropertySheetPageCallback(IntPtr hwnd, uint uMsg, uint uPage);}public class FileSecurityInfo : ISecurityInformation{public FileSecurityInfo(){}public const uint SI_PAGE_TITLE = 0x00000800;public const uint SI_EDIT_ALL = 0x00000003;// 实现接口方法public void GetObjectInformation(out SI_OBJECT_INFO pObjectInfo){pObjectInfo = new SI_OBJECT_INFO(){dwFlags = Flags, // SI_EDIT_PERMSpszObjectName = ObjectName,pszServerName = null,pszPageTitle = PageTitle,guidObjectType = Guid.Empty};}public string PageTitle;public string ObjectName;public string _filePath;public uint Flags = SI_PAGE_TITLE | SI_EDIT_ALL;public void GetSecurity(uint RequestedInformation, out IntPtr ppSecurityDescriptor, bool fDefault){ppSecurityDescriptor = IntPtr.Zero;// 获取文件的安全描述符var fileSecurity = File.GetAccessControl(_filePath);var rawSecurityDescriptor = fileSecurity.GetSecurityDescriptorBinaryForm();// 将安全描述符复制到非托管内存ppSecurityDescriptor = Marshal.AllocHGlobal(rawSecurityDescriptor.Length);Marshal.Copy(rawSecurityDescriptor, 0, ppSecurityDescriptor, rawSecurityDescriptor.Length);}public void SetSecurity(uint SecurityInformation, IntPtr pSecurityDescriptor){//if (!SetFileSecurity(_filePath, SecurityInformation, pSecurityDescriptor))//{// throw new System.ComponentModel.Win32Exception(Marshal.GetLastWin32Error());//}}// 其他接口方法留空（需根据需求实现）public void GetAccessRights(ref Guid pguidObjectType, uint dwFlags, out IntPtr ppAccess, out uint pcAccesses, out uint piDefaultAccess){ppAccess = IntPtr.Zero;pcAccesses = 0;piDefaultAccess = 0;}public void MapGeneric(ref Guid pguidObjectType, ref byte pAceFlags, ref uint pMask) { }public void GetInheritTypes(out IntPtr ppInheritTypes, out uint pcInheritTypes){ppInheritTypes = IntPtr.Zero;pcInheritTypes = 0;}public void PropertySheetPageCallback(IntPtr hwnd, uint uMsg, uint uPage) { }[DllImport("aclui.dll")][return: MarshalAs(UnmanagedType.Bool)]public static extern bool EditSecurity(IntPtr hwndOwner, ISecurityInformation psi);}"@ # 使用示例# 创建安全信息对象
