c#委托与事件+调用list<>的回调问题。

[chenjianyong94]

麻烦高手看看 我为什么调用eventGetDeviceByCallBack += new fGetDeviceByCallBack(GetInfo);它时，断点不进GetInfo函数。void GetInfo(NEWDHCP_INFO di)

[DllImport("AutoFindDevice.dll")]
    public static extern int Initial();
    [DllImport("AutoFindDevice.dll")]
    public static extern void Search();
    [DllImport("AutoFindDevice.dll")]
    public static extern long GetDeviceFromCallBack(fGetDeviceByCallBack eventGetDeviceByCallBack);

    public delegate void fGetDeviceByCallBack(NEWDHCP_INFO pDeviceInfo);
    private event fGetDeviceByCallBack eventGetDeviceByCallBack;
    private List<NEWDHCP_INFO> listd = new List<NEWDHCP_INFO>();

    protected void Page_Load(object sender, EventArgs e)
    {
        eventGetDeviceByCallBack += new fGetDeviceByCallBack(GetInfo);
    }
    void GetInfo(NEWDHCP_INFO di)
    {
        listd.Add(di);
    }
[StructLayoutAttribute(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
    public struct NEWDHCP_INFO
    {
        /// <summary>
        /// MAC地址
        /// </summary>
        [MarshalAsAttribute(UnmanagedType.ByValTStr, SizeConst = 20)]
        public string strhostmac;
        /// <summary>
    }

GetDeviceFromCallBack（eventGetDeviceByCallBack ）就这么调用啊，至于什么时候调用，看你需要了

[冰镇宝贝321]

调用GetDeviceFromCallBack(eventGetDeviceByCallBack)

[chenjianyong94]

坐等大家解释了

[bdmh]

你得调用GetDeviceFromCallBack，才能去执行回调过程

[传递正能量]

eventGetDeviceByCallBack什么时候被谁调用的呢？

被调用就会进到断点

2楼的大哥，我怎么去调用这个GetDeviceFromCallBack，不懂啊。请您指教。。。
