C#ReadProcessMemory:如何读取64位内存地址？

我正在阅读应用程序内存.我正在使用CheatEngine获取内存地址,然后尝试返回它的值.但是,CheatEngine似乎返回64位内存地址,所以我的ReadProcessMemory函数不断告诉我,每当我输入地址时它都不能将'long'转换为'int'.我发现的所有教程似乎都基于00AB5678的内存地址,但我得到的更像是D3569227FC.

所以我的问题是,如何将ReadProcessMemory与更大的内存地址一起使用？

这是我的代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.InteropServices;
using System.Diagnostics;

namespace ConsoleApplication1
{
    class Program
    {
        const int PROCESS_WM_READ = 0x0010;

        [DllImport("kernel32.dll")]
        public static extern IntPtr OpenProcess(int dwDesiredAccess, bool bInheritHandle, int dwProcessId);

        [DllImport("kernel32.dll")]
        public static extern bool ReadProcessMemory(int hProcess,
        int lpBaseAddress, byte[] lpBuffer, int dwSize, ref int lpNumberOfBytesRead);

        static void Main(string[] args)
        {
            Process process = Process.GetProcessesByName("MyProgram")[0]; 
            IntPtr processHandle = OpenProcess(PROCESS_WM_READ, false, process.Id); 

            int bytesRead = 0;
            byte[] buffer = new byte[24]; //To read a 24 byte unicode string

            ReadProcessMemory((int)processHandle, 0xD5369227FC, buffer, buffer.Length, ref bytesRead);

            Console.WriteLine(Encoding.Unicode.GetString(buffer) + 
                  " (" + bytesRead.ToString() + "bytes)");
            Console.ReadLine();
        }
    }
}

编辑:我已经将我的C#应用​​程序转换为64位应用程序,进入VS2012 - >项目 - > ApplicationName属性 - >构建 - >平台目标 - >更改为"x64",现在我只需要知道如何更改我的代码以读取64位地址.

您可以将lpBaseAddress路径为Int64.尝试更换你的

[DllImport("kernel32.dll")]
    public static extern bool ReadProcessMemory(int hProcess,
    int lpBaseAddress, byte[] lpBuffer, int dwSize, ref int lpNumberOfBytesRead);

至

[DllImport("kernel32.dll")] 
public static extern bool ReadProcessMemory(int hProcess,
    Int64 lpBaseAddress, byte[] lpBuffer, int dwSize, ref int lpNumberOfBytesRead);
