c#读取进程内存-未知错误

我试图从游戏中读取内存，以便我可以获得一些值并制作一个好的Bot。但是我总是返回int 0，我没有发现任何错误。这是我第一次尝试用c#编写这些东西，我希望我们能找到一个解决方案，谢谢你的回答。

PS:如果我尝试读取内存的软件是"以管理员权限运行"，我有一个错误:"UInt32 Base = (UInt32)game.MainModule.BaseAddress.ToInt32();"。

这是代码:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    [DllImport("kernel32.dll")]
    public static extern Int32 ReadProcessMemory(IntPtr hProcess, IntPtr lpBaseAddress,
    [In, Out] byte[] buffer, UInt32 size, out IntPtr lpNumberOfBytesRead);
    public static byte[] ReadBytes(IntPtr Handle, Int64 Address, uint BytesToRead)
    {
        IntPtr ptrBytesRead;
        byte[] buffer = new byte[BytesToRead];
        ReadProcessMemory(Handle, new IntPtr(Address), buffer, BytesToRead, out ptrBytesRead);
        return buffer;
    }
    public static int ReadInt32(long Address, uint length = 4, IntPtr? Handle = null)
    {
        return BitConverter.ToInt32(ReadBytes((IntPtr)Handle, Address, length), 0);
    }
    public static string ReadString(long Address, uint length = 32, IntPtr? Handle = null)
    {
        string temp3 = ASCIIEncoding.Default.GetString(ReadBytes((IntPtr)Handle, Address, length));
        string[] temp3str = temp3.Split(''0');
        return temp3str[0];
    }


    private void btnLeggi_Click(object sender, EventArgs e)
    {
        UInt32 Address = 0x00075140;
        // get process
        Process game = Process.GetProcessesByName("Prison Architect")[0];
        // dump base
        UInt32 Base = (UInt32)game.MainModule.BaseAddress.ToInt32();
        // read pointer
        UInt32 Ptr1 = (UInt32)ReadInt32(Address + Base, 4, game.Handle);
        UInt32 Ptr2 = (UInt32)ReadInt32(Ptr1 + 0x300, 4, game.Handle);
        UInt32 Ptr3 = (UInt32)ReadInt32(Ptr2 + 0x88, 4, game.Handle);
        UInt32 Ptr4 = (UInt32)ReadInt32(Ptr3 + 0x26c, 4, game.Handle);
        UInt32 Ptr5 = (UInt32)ReadInt32(Ptr4 + 0x70, 4, game.Handle);
        UInt32 Ptr6 = (UInt32)ReadInt32(Ptr5 + 0x328, 4, game.Handle);
        // read memory pointer points to
        int PtrRead = ReadInt32(Ptr6, 255, game.Handle);

        txtDato.Text = Convert.ToString( PtrRead);
