C# 有人可以发送ReadInt32来写入进程内存吗？

我试图写处理内存，所以我复制了视频中的代码。 但是这个视频没有显示函数“ReadInt32”，有人能让我最终运行这个应用程序吗

ReadInt32（进程，（IntPtr）地址）

代码中突出显示的错误：

指针：（类型为float）

public static long GetRealAddress(IntPtr process, IntPtr baseAddress, int[] offsets)
    {
        var address = baseAddress.ToInt64();
        foreach (var offset in offsets)
        {
            address = ReadInt32(process, (IntPtr)address) + offset;

        }
        return address;
    }

[DllImport("kernel32.dll", SetLastError = true)]
static extern bool ReadProcessMemory(IntPtr handle, IntPtr baseAddress,
    byte[] buffer, int size, out IntPtr lpNumberOfBytesRead);


public static int ReadInt32(IntPtr processHandle, IntPtr address)
{
    byte[] buffer = new byte[4];

    ReadProcessMemory(processHandle, address,
       buffer, buffer.Length, out IntPtr bytesRead);

    // if this gives the wrong value:
    // Array.Reverse(buffer);
    var myInt = BitConverter.ToInt32(buffer, 0);
    return myInt;
}
