创建一个示例和WebMethod特性解析
系列文章导航：
现在开始学习Web服务，写下自己学习过程中的一些感受，拿出来与大家分享，欢迎批评指正。希望能给跟我一样初学Web服务的朋友一些帮助。
Web服务的宗旨是创建不需要用户界面就能与其他应用程序交互的Web应用程序。它是松耦合的，并与服务器端和客户端所使用的操作系统、编程语言都无关，这样就在一定的情况下就会使你的效率大大提高。但创建Web服务必须保证的是，服务器端和客户端都要支持行业标准协议HTTP、SOAP（simple object access protocal 简单对象访问协议）和XML。
创建Web服务的过程：
(1):打开VS，创建一个ASP.NET WEB服务应用程序；
(2):输入下列代码，这是一个有关学生信息的二维数组和几个方法
//构造并填充info数组
string[,] strStuInfo ={
