有人可以给我一个AllocateAndInitializeSid从 C# 代码调用函数的完整且有效的示例吗？

我发现了这个： 

BOOL WINAPI AllocateAndInitializeSid(
  __in   PSID_IDENTIFIER_AUTHORITY pIdentifierAuthority,
  __in   BYTE nSubAuthorityCount,
  __in   DWORD dwSubAuthority0,
  __in   DWORD dwSubAuthority1,
  __in   DWORD dwSubAuthority2,
  __in   DWORD dwSubAuthority3,
  __in   DWORD dwSubAuthority4,
  __in   DWORD dwSubAuthority5,
  __in   DWORD dwSubAuthority6,
  __in   DWORD dwSubAuthority7,
  __out  PSID *pSid
);

而且我不知道如何构造此方法的签名 - 我应该如何处理PSID_IDENTIFIER_AUTHORITY和PSID类型？我应该如何通过它们 - 使用refor out？

使用P/Invoke 互操作助手：

    [System.Runtime.InteropServices.StructLayoutAttribute(System.Runtime.InteropServices.LayoutKind.Sequential)]
    public struct SidIdentifierAuthority {

        /// BYTE[6]
        [System.Runtime.InteropServices.MarshalAsAttribute(
            System.Runtime.InteropServices.UnmanagedType.ByValArray, 
            SizeConst = 6, 
            ArraySubType = 
            System.Runtime.InteropServices.UnmanagedType.I1)]
        public byte[] Value;
    }

    public partial class NativeMethods {

        /// Return Type: BOOL->int
        ///pIdentifierAuthority: PSID_IDENTIFIER_AUTHORITY->_SID_IDENTIFIER_AUTHORITY*
        ///nSubAuthorityCount: BYTE->unsigned char
        ///nSubAuthority0: DWORD->unsigned int
        ///nSubAuthority1: DWORD->unsigned int
        ///nSubAuthority2: DWORD->unsigned int
        ///nSubAuthority3: DWORD->unsigned int
        ///nSubAuthority4: DWORD->unsigned int
        ///nSubAuthority5: DWORD->unsigned int
        ///nSubAuthority6: DWORD->unsigned int
        ///nSubAuthority7: DWORD->unsigned int
        ///pSid: PSID*
        [System.Runtime.InteropServices.DllImportAttribute("advapi32.dll", EntryPoint = "AllocateAndInitializeSid")]
        [return: System.Runtime.InteropServices.MarshalAsAttribute(System.Runtime.InteropServices.UnmanagedType.Bool)]
        public static extern bool AllocateAndInitializeSid(
            [System.Runtime.InteropServices.InAttribute()] 
            ref SidIdentifierAuthority pIdentifierAuthority, 
            byte nSubAuthorityCount, 
            uint nSubAuthority0, 
            uint nSubAuthority1, 
            uint nSubAuthority2, 
            uint nSubAuthority3, 
            uint nSubAuthority4, 
            uint nSubAuthority5, 
            uint nSubAuthority6, 
            uint nSubAuthority7, 
            out System.IntPtr pSid);

    }

如果您的目标是 .NET 2.0 或更高版本，则 System.Security.Principal.SecurityIdentifier 类包装一个 SID 并允许您避免容易出错的 Win32 API。

不完全是您问题的答案，但谁知道它可能有用。
