要实现内存块的显示，需要实现IDebugMemoryBytes2接口，类似这样的：

    class AD7MemoryBytes : IDebugMemoryBytes2    {        private AD7Engine _engine;        public AD7Engine Engine { get { return _engine; } }        public AD7MemoryBytes(AD7Engine engine)        {            _engine = engine;        }        public int GetSize(out ulong pqwSize)        {            throw new NotImplementedException();        }        public int ReadAt(IDebugMemoryContext2 pStartContext, uint dwCount, byte[] rgbMemory, out uint pdwRead, ref uint pdwUnreadable)        {            AD7MemoryAddress addr = pStartContext as AD7MemoryAddress;            pdwRead = dwCount;            pdwUnreadable = 0;            return Constants.S_OK;        }        public int WriteAt(IDebugMemoryContext2 pStartContext, uint dwCount, byte[] rgbMemory)        {            throw new NotImplementedException();        }

当VS显示内存窗口时，会调用：

        // The memory bytes as represented by the IDebugMemoryBytes2 object is for the program's image in memory and not any memory         // that was allocated when the program was executed.        public int GetMemoryBytes(out IDebugMemoryBytes2 ppMemoryBytes)        {            ppMemoryBytes = new AD7MemoryBytes(this);            return Constants.S_OK;        }

这里仅仅实现了一个空接口，并没有实现内存实际值的刷新，但此时已经可以在IDE中看到这样的效果了：

在读取数据的接口中使用gdb的-data-read-memory实际读取数据并填充后就成了这样：

搞定！
