C++写的动态库中的结构在C#中怎么声明（2）

Question

最后一个不是指针么
用 Marshal.PtrToStructure(IntPtr, Type) 
将内存拷贝到一个结构体里面,就可以了.

Answer 1

我也想到这个方法了，但没用成功，我把我的代码贴出来，麻烦您帮我看看：
我的结构：
 [StructLayout(LayoutKind.Sequential)]
    public struct PEvent
    {
        public byte Code;
        public byte DotID;
        public TCardNumber CardNumber;
        public ushort reserved;
        public Time Time;
        public IntPtr pNext;
    }
 public void GetEvent()
           {
            byte Bagid=this.SEventBagId;
            byte EventCount = this.SEventCount;
            int rs = 0; string Str = ""; int i = 0;
            EkcoTog.PEvent Event = new EkcoTog.PEvent();
            EkcoTog.PEvent lpNext = new EkcoTog.PEvent();
            try
            {
                Bagid = SEventBagId;
                EventCount = SEventCount;
               // MessageBox.Show("success");
                rs = EkcoTog.DPU3001_Dll.NT_GetEvent(LineID, CtrlID, ref Bagid, ref EventCount, ref Event);
                this.listBox1.Items.Add(rs.ToString());
                if (rs == 0)
                {
                    SEventBagId = Bagid; //Save event package number for next time
                    SEventCount = EventCount;  //Save event count for next time
                         EkcoTog.PEvent[] Sevent = new PEvent[EventCount];
                    string str = "Bag ID:" + Bagid.ToString() + "EventCount:" + EventCount.ToString();
                    this.listBox1.Items.Add(str);
                    lpNext = Event;
                    for (i = 0; i < EventCount; i++)
                    {                     
                        int m = i + 1;
                        Str += m.ToString() + " DateTime:" + lpNext.Time.wMonth.ToString() + "-" + lpNext.Time.wDayOfWeek.ToString() + "-" + lpNext.Time.wHour.ToString();
                        Str += " " + lpNext.Time.wMinute.ToString() + ":" + lpNext.Time.wSecond.ToString() + ":" + lpNext.Time.wMilliseconds.ToString();
                        Str += " Event Code:" + lpNext.Code.ToString();
                        Str += " Component Address:" + lpNext.DotID.ToString();
                        Str += " Card Offset: " + lpNext.CardNumber.dwCardNo.ToString() + "   THIS IS END!"+lpNext.pNext.ToString();
                        this.listBox1.Items.Add(Str);
                        //lpNext.pNext = Event.pNext;
                        //lpNext = ptr;
                        // lpNext = lpNext.pNext.ToPointer();
                        //IntPtr p = lpNext.pNext;
                        //lpNext.pNext = IntPtr.Zero;
                        IntPtr ptr = Marshal.ReadIntPtr(Event, i);
                        Sevent[i] = (PEvent)Marshal.PtrToStructure(Event.pNext, typeof(PEvent));
                        return;
                    }
                }
                if (rs == 133)
                {
                    this.listBox1.Items.Add("所有事件都已经上载，没有新事件！");
                }
                else
                {
                    this.listBox1.Items.Add("获取事件失败！" + rs.ToString());
                }
            }
            catch
            {
                //  this.listBox1.Items.Add("WW！");
            }
           }

Answer 2

Marshal.PtrToStructure(Event.pNext, Event );

Answer 3

能不能具体点啊
Marshal.PtrToStructure(Event.pNext, Event );
