C#实现WebService服务 项目完整总结先说一下这个项目做了什么。先介绍一下背景(备注一下，每次项目发生更改之后，要进行clean 和rebuild两个操作，否则最新的更改保存不到exe文件中，这样上线后的系统还是执行得原有的已编译过的程序代码，所以得出的结论就是在上线测试阶段，对于程序代码的每一次更改都要rebuild操作，来保证每次的更改作用于exe文件，保证编译是最新的；；)
上面这个流程图介绍了当我们需要take training follow-up的时候，我们需要在sharepoint Desinger中设置工作流，来完成这些功能，但是现在遇到一个问题，workflow的触发是由于登录页面的用户log一条item记录的时候触发的，如果我们要实现邮件的定时提醒功能，那么就需要在每天都触发执行一次workflow，但是由谁来触发呢？刚开始网上搜了很多资料，内网 外网资料都搜了一圈，好不容易看到一个帖子说可以实现，但最后试着用workflow来解决，但是始终行不通，就算让它执行个15分钟，过了会儿就会挂掉。我估计系统可能开着这个线程太占用系统资源了。最终逼不得已才决定使用web service来解决这个问题，但是问题又来了，对于java还算了解，但是对C#还是完全陌生，如果采用C#来做这个定时发送邮件的功能的话，带来的risk无法估量，而且极有可能造成PRoject的delay，所以在前期的决策上，试着采用了Java做了一部分调研，但是考虑到公司的sharepoint是部署位置及其Java与windows底层通信协议可能带来的risk:项目进行到后期，极有可能无法完成，所以最终决定用C#来实现这个功能。。
该学习的技术还是要学的，你越逃避的事情，它越会找上你。所以，学习新技术也要趁早，等你的项目中需要用到的时候，你已经可以游刃有余了。
如上，为C#程序中要实现的逻辑。程序的整体实现逻辑是这样的。我们取出list列表，然后进行过滤，当满足我们的要求的时候，我们发邮件，然后做一些异常处理。Servic.cs代码如下：
