SharePoint solution auto-retract using Selenium(C#)

---恢复内容开始---

本来的想法是做一个可以自动卸载并且部署新solution到SharePoint farm的tool。但是最后只做到retract成功和remove solution之前这个阶段。因为一个原因（等待solution retracted的过程中出现CLR方面的问题）导致不能将整个过程连续起来，这是相关的博问，希望有高手可以解惑。

下面的tool将会根据SharePoint solution wsp文件名自动识别solution，并在相应的站点deactive相应的site collection级别的solution feature，然后在SharePoint farm中卸载相应的solution。

图形界面：

选择Web Application，选择其下的Site Collection，然后填写登陆SharePoint Site的用户名和密码，选择要卸载的wsp文件。之后点击OK，就会自动进行卸载。

待完成的部分用红色字体标注出来了，是等待retract成功，然后remove solution，deploy solution，以及active feature的过程。难点主要是 等待solution retract成功 。希望SharePoint方面专家可以帮助解决这个问题。相关的详细异常信息，请见博问。

代码如下：
