如何从C#调用AllocateAndInitializeSid函数？

有人能给我一个完整的工作示例，从C#code调用

AllocateAndInitializeSid

函数吗

我发现：

---

我不知道如何构造此方法的签名-我应该如何处理

PSID\u IDENTIFIER\u AUTHORITY

和

PSID

类型？我应该如何传递它们-使用

ref

或

out

？

For Platform Invoke www.pinvoke.net是您的新好友

如果您的目标是.NET 2.0或更高版本，则类System.Security.Principal.SecurityIdentifier包装SID，并允许您避免易出错的Win32 API

不完全是你问题的答案，但谁知道它可能有用。

使用：

我去过那里。根据MSDN，第一个参数是“指向SID_标识符_权限结构的指针”，pinvoke.net称其为IntPtr。是一样的吗？我应该如何创建thsi指针？请张贴一个完整的例子。我尝试了我在网上找到的所有东西，但我无法让它工作。

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
);

    [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

        [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 nSubAuthority6, 
            uint nSubAuthority7, 
            out System.IntPtr pSid);
