要在C#中使用AoBScan获取memory.dll的值，可以使用以下代码示例：

using System;
using System.Diagnostics;

namespace AoBScanExample
{
    class Program
    {
        static void Main(string[] args)
        {
            Process process = Process.GetProcessesByName("your_process_name")[0];
            IntPtr baseAddress = process.MainModule.BaseAddress;
            int moduleSize = process.MainModule.ModuleMemorySize;

            byte[] pattern = new byte[] { 0x11, 0x22, 0x33, 0x44 }; // 设置要扫描的模式
            byte[] mask = new byte[] { 0xFF, 0xFF, 0xFF, 0xFF }; // 设置掩码

            IntPtr address = AoBScan(process.Handle, baseAddress, moduleSize, pattern, mask);
            if (address != IntPtr.Zero)
            {
                byte[] buffer = new byte[4];
                int bytesRead = 0;
                ReadProcessMemory(process.Handle, address, buffer, buffer.Length, ref bytesRead);

                int value = BitConverter.ToInt32(buffer, 0);
                Console.WriteLine($"Value found at address 0x{address.ToString("X")} is {value}");
            }
            else
            {
                Console.WriteLine("Value not found.");
            }
        }

        // AoBScan函数，用于在指定进程的内存中搜索指定的字节模式
        static IntPtr AoBScan(IntPtr processHandle, IntPtr baseAddress, int size, byte[] pattern, byte[] mask)
        {
            byte[] buffer = new byte[size];
            int bytesRead = 0;
            ReadProcessMemory(processHandle, baseAddress, buffer, size, ref bytesRead);

            for (int i = 0; i < size; i++)
            {
                bool found = true;
                for (int j = 0; j < pattern.Length; j++)
                {
                    if (mask[j] != 0xFF && (buffer[i + j] & mask[j]) != (pattern[j] & mask[j]))
                    {
                        found = false;
                        break;
                    }
                }

                if (found)
                {
                    return baseAddress + i;
                }
            }

            return IntPtr.Zero;
        }

        // ReadProcessMemory函数，用于从指定进程的内存中读取数据
        static void ReadProcessMemory(IntPtr processHandle, IntPtr address, byte[] buffer, int size, ref int bytesRead)
        {
            Win32API.ReadProcessMemory(processHandle, address, buffer, size, ref bytesRead);
        }
    }

    // Win32API类，用于导入kernel32.dll中的ReadProcessMemory函数
    class Win32API
    {
        [System.Runtime.InteropServices.DllImport("kernel32.dll")]
        public static extern bool ReadProcessMemory(IntPtr hProcess, IntPtr lpBaseAddress, byte[] lpBuffer, int nSize, ref int lpNumberOfBytesRead);
    }
}

请注意，上述代码仅用于演示目的，并未完全测试和优化。你需要将"your_process_name"替换为你要扫描的进程的名称，并根据具体情况修改模式和掩码。确保在运行代码之前，你已经打开了目标进程。

此外，这个例子使用了ReadProcessMemory函数来读取进程的内存数据。请确保你有足够的权限来读取目标进程的内存。
