摘要: 小弟关注cnblogs有一段时间了，每天上班第一件事是打开博客园关注里面的最新博客(当然开会或其它特殊情况就例外了，哈哈)，这段时间工作不忙,刚刚申请开通了属于自己的blog，没想到cnblogs的管理员办事效率如此之高（真是令人倍感兴奋!），从提交申请到审核通过只等待了31分钟，在此先谢过啦。这是我的第一篇blog，希望各位帅哥美女不要扔太多砖头鸡蛋(小弟害怕太暴力哦!)，写得不好的地方，也希望...阅读全文

前段时间看见别人写的一篇 c#调用网络摄像头的，正好搬到的新的地方，这地儿洗脸的地方木有镜子用，每天起床，头发总是很乱，也不想专门去超市买个镜子，又正好笔记本上有个摄像头，平时也木有MM跟偶视频聊天，纯粹的浪费了一个多好的功能，突发"奇想"，视频不就是实时的吗，何不写个客户端程序，把摄像头当镜子用呢，想到此处，所以把别人的代码copy过来以定制偶整理头发的镜子，不过发现copy过来的代码偶尔不工作，重新修改了下，基本当个镜子木有问题了（当然木有镜子清晰!），只是有一个问题至今还木解决，视频源窗口偶尔会弹出来，不知道哪个筒子能解决，如下图(左)，另外一张就是偶的镜子程序，刚下班回来，头发还不乱，稍加整理了下，截个了屏 #_#
刚下班，所以人有点累，废话不多话，直接上代码，如下，希望对这个有兴趣的筒子也可以借鉴下，大家相互借鉴，相信总是可以做得更好 ：）

排列控件的Designer代码就不贴了，就一个panel控件，相信大家一看就懂的:) , 实现这个“镜子”的代码，所花的时间还真的比去超市的买个镜子花的时间少哈，而且还变废为宝，c#真不愧是快餐语言，够快，够方便的 :)

摘要: 好久没有做web了，JSON目前比较流行，闲得没事，所以动手试试将对象序列化为JSON字符（尽管DotNet Framework已经有现成的库，也有比较好的第三方开源库）,而且只是实现了处理简单的类型,并且DateTime处理的也不专业，有兴趣的筒子可以扩展，代码比较简单，反序列化木有实现:( ，直接贴代码吧，都有注释了，所以废话不多说 :)测试类///<summary>///NestedclassofPerson.///</summary>publicclassHouse{publicstringName{get;set;}publicdoublePrice{get;阅读全文

接着昨天的博客 零代码配置xml维护单表 ，今天上午上班啥事没做也没啥事做，一心想接着昨天的文章搞一个简单版的demo，然后就整理出了这么个阉割版本的demo，在这个版本中，去掉了分层和自定义控件扩展,sql操作代码也放在了页面中，有兴趣的可以看昨天那篇文章自行扩展。
demo结构目录如下：
crud操作在于三个页面commonAdd.aspx(添加页),commonEdit.aspx(编辑查看页),commonQuery.aspx(列表页),另外加一个配置文件config.xml
,config.xml文件对应了数据库建立的表配置，另外app_code/t_column.cs是对xml表配置实体的一个封装，每个配置信息代表什么意思，里面都已经注释了
数据库放在app_data里面，自己还原
下面对demo作简单介绍：
1.建立数据库：(偷个懒，列直接用中文了)
配置xml
1 <?xml version="1.0" encoding="utf-8" ?>
