如何从C#调用AllocateAndInitializeSid函数?

有人可以给我一个完整有效的示例,从Ccode调用AllocateAndInitializeSid函数吗?

我找到了这个:

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
);

并且我不知道如何构造该方法的签名,对PSID_IDENTIFIER_AUTHORITYPSID类型应该怎么做?我该如何使用ref或者out传递它们?

对于平台调用,www.pinvoke.net是新好朋友!

如果我们以.NET 2.0或者更高版本为目标,则类System.Security.Principal.SecurityIdentifier会包装一个SID,并允许我们避免容易出错的Win32 API。

不完全是问题的答案,但是谁知道这可能是有用的。

使用P / Invoke Interop Assistant:

[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);

    }
