如何在C＃中获取登录SID

Question

一个人如何在c＃.net中检索Windows登录SID？ （不是用户SID，而是每个会话的唯一新的）

Answer 1

恐怕您必须求助于使用P/Invoke。有一个例子如何做 pinvoke.net （请参阅页面底部）：

Result = GetTokenInformation(WindowsIdentity.GetCurrent().Token, TOKEN_INFORMATION_CLASS.TokenSessionId , TokenInformation , TokenInfLength , out TokenInfLength );

请注意，我只需更改一行就更改了示例，我替换了 TOKEN_INFORMATION_CLASS.TokenUser 和 TOKEN_INFORMATION_CLASS.TokenSessionId 这正是您需要的。

希望这可以帮助。

更新：这是工作（至少在我的计算机上）代码：

using System;
using System.Runtime.InteropServices;
using System.Security.Principal;

namespace LinqTest
{
    public class ClsLookupAccountName
    {
        public const uint SE_GROUP_LOGON_ID = 0xC0000000; // from winnt.h
        public const int TokenGroups = 2; // from TOKEN_INFORMATION_CLASS

        enum TOKEN_INFORMATION_CLASS
        {
            TokenUser = 1,
            TokenGroups,
            TokenPrivileges,
            TokenOwner,
            TokenPrimaryGroup,
            TokenDefaultDacl,
            TokenSource,
            TokenType,
            TokenImpersonationLevel,
            TokenStatistics,
            TokenRestrictedSids,
            TokenSessionId,
            TokenGroupsAndPrivileges,
            TokenSessionReference,
            TokenSandBoxInert,
            TokenAuditPolicy,
            TokenOrigin
        }

        [StructLayout(LayoutKind.Sequential)]
        public struct SID_AND_ATTRIBUTES
        {
            public IntPtr Sid;
            public uint Attributes;
        }

        [StructLayout(LayoutKind.Sequential)]
        public struct TOKEN_GROUPS
        {
            public int GroupCount;
            [MarshalAs(UnmanagedType.ByValArray, SizeConst = 1)]
            public SID_AND_ATTRIBUTES[] Groups;
        };

        // Using IntPtr for pSID instead of Byte[]
        [DllImport("advapi32", CharSet = CharSet.Auto, SetLastError = true)]
        static extern bool ConvertSidToStringSid(IntPtr pSID, out IntPtr ptrSid);

        [DllImport("kernel32.dll")]
        static extern IntPtr LocalFree(IntPtr hMem);

        [DllImport("advapi32.dll", SetLastError = true)]
        static extern bool GetTokenInformation(
            IntPtr TokenHandle,
            TOKEN_INFORMATION_CLASS TokenInformationClass,
            IntPtr TokenInformation,
            int TokenInformationLength,
            out int ReturnLength);

        public static string GetLogonId()
        {
            int TokenInfLength = 0;
            // first call gets lenght of TokenInformation
            bool Result = GetTokenInformation(WindowsIdentity.GetCurrent().Token, TOKEN_INFORMATION_CLASS.TokenGroups, IntPtr.Zero, TokenInfLength, out TokenInfLength);
            IntPtr TokenInformation = Marshal.AllocHGlobal(TokenInfLength);
            Result = GetTokenInformation(WindowsIdentity.GetCurrent().Token, TOKEN_INFORMATION_CLASS.TokenGroups, TokenInformation, TokenInfLength, out TokenInfLength);

            if (!Result)
            {
                Marshal.FreeHGlobal(TokenInformation);
                return string.Empty;
            }

            string retVal = string.Empty;
            TOKEN_GROUPS groups = (TOKEN_GROUPS)Marshal.PtrToStructure(TokenInformation, typeof(TOKEN_GROUPS));
            int sidAndAttrSize = Marshal.SizeOf(new SID_AND_ATTRIBUTES());
            for (int i = 0; i < groups.GroupCount; i++)
            {
                SID_AND_ATTRIBUTES sidAndAttributes = (SID_AND_ATTRIBUTES)Marshal.PtrToStructure(
                    new IntPtr(TokenInformation.ToInt64() + i * sidAndAttrSize + IntPtr.Size), typeof(SID_AND_ATTRIBUTES));
                if ((sidAndAttributes.Attributes & SE_GROUP_LOGON_ID) == SE_GROUP_LOGON_ID)
                {
                    IntPtr pstr = IntPtr.Zero;
                    ConvertSidToStringSid(sidAndAttributes.Sid, out pstr);
                    retVal = Marshal.PtrToStringAuto(pstr);
                    LocalFree(pstr);
                    break;
                }
            }

            Marshal.FreeHGlobal(TokenInformation);
            return retVal;
        }
    }
}

NB我在X64机器上测试了它，所以请密切注意 TokenInformation.ToInt64() 一件代码，也许您应该用 TokenInformation.ToInt32()

system.security.principal.windowsidentity.getCurrent（）。user.accountdomainsid-是否可以解决问题？

Answer 3

我知道这是一个古老的帖子。只需遇到这个问题，我必须获得ICA会话ID和RDP会话ID才能让程序收集适用于每种远程连接的正确变量。当前的会话ID位于Regedit Hkey_current_user Remote*中。由于我找不到WTS的任何替代方案，因此我在此处发布解决方案。

    // Prints out ICA or RDP session ID of current user 

using System;
using Microsoft.Win32;

namespace ViaRegedit
{
    class Program03
    {
        static void Main(string[] args)
        {
            // Obtain an instance of RegistryKey for the CurrentUser registry 
            RegistryKey rkCurrentUser = Registry.CurrentUser;
            // Obtain the test key (read-only) and display it.
            RegistryKey rkTest = rkCurrentUser.OpenSubKey("Remote");
            foreach (string valueName in rkTest.GetSubKeyNames())
            {
                //Getting path to RDP/Citrix session ID
                string RDPICApath = "";
                if (rkTest.OpenSubKey(valueName) != null && rkTest.OpenSubKey(valueName) != null) { RDPICApath = rkTest.OpenSubKey(valueName).ToString(); }
                Console.WriteLine("Getting CurrentUser ICA-RDP path from string = " + RDPICApath);

                //Seperating RDPICApath to get session number
                string RDPICAnumber = RDPICApath.Substring(RDPICApath.LastIndexOf('\\') + 1);
                Console.WriteLine("Current User RDPICAnumber = " + RDPICAnumber);
            }
            rkTest.Close();
            rkCurrentUser.Close();
            Console.ReadLine();
        }
    }

}
