c#读取进程内存

My class that i use:http://pastebin.com/GMq5eZ42

我在主应用程序中这样调用它但它仍然说索引不在arrayfield

        int memoryaddress = 0x5C;
        int bytesread;
        double memoryaddressvalue;
        byte[] memoryvalue;

        memoryvalue = ReadCoords.ReadMemoryAtAdress((IntPtr)memoryaddress, 4, out bytesread);

        memoryaddressvalue = BitConverter.ToDouble(memoryvalue, 0);
        Label1 = Convert.ToString(memoryaddressvalue);
