C#中的BYTE*数组

本文关键字：数组 BYTE 中的 | 更新日期: 2023-09-27 18:27:49

我正在尝试调用非托管函数。我用C++称之为：这是与我合作的测试项目

// ConsoleApplication5.cpp : main project file.
#include "stdafx.h"
#include <windows.h>
#include <stdio.h>
#include <string>
using namespace System;
typedef int(*Funcs)(int, BYTE (*)[90], BYTE (*)[90]);
int main(array<System::String ^> ^args)
{
BYTE Input[] =
        {
                    0x7f,0x06,0x02,0x66,0xd2,0x3e,0x4c,0x7f,0x50,0x0a,0x5a,0x3c,0xab,0x43,0x5d,0x51,0x47,0xe5,0    x94,0x49,0xbd,0xef,0xc2,0xe4
,0x6c,0xb1,0x3b,0x3d,0x7c,0x47,0x65,0x8f,0x67,0xa6,0xe8,0x6a,0xe9,0x0e,0xbd,0x93,0xad,0x4a,    0x31,0x68,0x82,0x02,0xe6,0x7e,0x01,0x36,0xa,
9,0x75,0xf7,0xa0,0xb9,0xe9,0x1b,0x09,0xba,0x19,0x8c,0x97,0x18,0x9c,0xcc,0xd8,0x87,0x0e,0x04    ,0xb3,0x7c,0xc2,0xbf,0x1e,0x42,0x3e,0x8b,0x64,0xf5,0x60,0x43,0x96,0xe7,0xf6,0x7d,0x54,0x84,    0x54,0x00
        };
            BYTE OutPut[90];
Funcs Funcis;
HMODULE x = LoadLibrary(L"E:''Games''Silkroad''HackShield''ehsvc.dll");
Funcis = (Funcs)GetProcAddress(x,"16");
Funcis(13,&Input,&OutPut);
FILE * pFile;
pFile = fopen ("myfile.bin", "wb");
fwrite (OutPut , sizeof(char), sizeof(OutPut), pFile);
fclose (pFile);
Console::Read();
}

但当我用C#调用它时：

delegate int GetResponseD(int Code, byte[] Input, byte[] OutPut);
...
IntPtr hModule = LoadLibrary(@"###.dll");
IntPtr hFunc = GetProcAddress(hModule, "10");
GetResponseD Get = (GetResponseD)Marshal.GetDelegateForFunctionPointer(hFunc, typeof(GetResponseD));
GetResponse(13, Input, OutPut);

我得到第一个只有字节的

C#中的BYTE*数组

类似的东西，如果数组是由dll:中的方法分配的

// You will probably have to free in some way Input and Output
delegate int GetResponseD(int Code, ref IntPtr Input, ref IntPtr OutPut);
static void Main()
{
    IntPtr input = IntPtr.Zero, output = IntPtr.Zero;
    GetResponseD grd = null; // something
    int res = grd(1, out input, out output);
    var input2 = new byte[90];
    var output2 = new byte[90];
    Marshal.Copy(input, input2, 0, input2.Length);
    Marshal.Copy(output, output2, 0, output2.Length);
    // Remember that you have to free input and output!
}

在C#中，不能使用非托管数组。您必须在托管阵列中复制他们的数据（不完全正确，但对于您的需要来说足够正确）

对于其他呼叫模式，请尝试：

delegate int GetResponseD(int Code, ref IntPtr Input, ref IntPtr OutPut);
byte[] input = new byte[] {
    0x7f,0x06,0x02,0x66,0xd2,0x3e,0x4c,0x7f,0x50,0x0a,0x5a,0x3c,0xab,0x43,0x5d,0x51,0x47,0xe5,0x94,0x49,0xbd,0xef,0xc2,0xe4,0x6c,0xb1,0x3b,0x3d,0x7c,0x47,0x65,0x8f,0x67,0xa6,0xe8,0x6a,0xe9,0x0e,0xbd,0x93,0xad,0x4a,0x31,0x68,0x82,0x02,0xe6,0x7e,0x01,0x36,0xa,9,0x75,0xf7,0xa0,0xb9,0xe9,0x1b,0x09,0xba,0x19,0x8c,0x97,0x18,0x9c,0xcc,0xd8,0x87,0x0e,0x04,0xb3,0x7c,0xc2,0xbf,0x1e,0x42,0x3e,0x8b,0x64,0xf5,0x60,0x43,0x96,0xe7,0xf6,0x7d,0x54,0x84,0x54,0x00
};
byte[] output = new byte[90];
GetResponseD grd = null; // something
GCHandle h1 = GCHandle.Alloc(input, GCHandleType.Pinned);
GCHandle h2 = GCHandle.Alloc(output, GCHandleType.Pinned);
IntPtr p1 = h1.AddrOfPinnedObject();
IntPtr p2 = h2.AddrOfPinnedObject();
grd(13, ref p1, ref p2);
h1.Free();
h2.Free();

检查您的字节序列，我认为在第三行的开头有一个,0 x94和一个没有0x的9。

据我所见，这个方法有多种调用方式，第一个参数充当"开关"，另外两个参数基于第一个参数进行解释。
