C# 海康DVR客户端开发系列（2）—— 封装API
前言
从上篇文章（10月4日）到本篇文章截止到今天（10月22日）一直在做这个SDK翻译工作，耗时2周半，代码超过1万行，约有三分之二的行数是注释。由于工作忙也只能一天抽出那么半个小时一个小时来整理，所以对关注此系列文章的朋友说句：“抱歉，让大家久等了”。
临时决定本系列使用WPF来做例子(买了一本WPF没读 - - #，所以......)，藉此学习下WPF，也进一步熟悉.Net Framework 3.5，落伍的“老兵”奋起追击下相对于“老兵”而言的新技术 :)
其实这篇文章在10月22日就写好了，但是想和视频预览文章一起发布，比较麻烦的是我这边朋友的DVR一直不稳定，一直拖延到今天还是不行，所以还是把本文先发了。因此寻求能提供DVR设备的厂家或者提供DVR远程访问地址的朋友，以支持此系列能顺利的完成，在这里先谢谢了！

更新
本文会随着后续实践文章有相应的改动，请及时更新！
2010-12-21 HCNetSDK2010-12-21.rar
主要更新了SerialDataCallBack委托的pRecvDataBuffer参数数据类型，由string改为byte[]，这里感谢badnewfish实践后指出，欢迎大家积极反馈！
2009-10-31 HCNetSDK2009-10-31.rar
主要更新了大部分结构体中byte[]初始大小指定，加上了[MarshalAs(UnmanagedType.ByValArray, SizeConst = HCNetSDK.SERIALNO_LEN)]类似的标记。
