ASP.NET 2.0 AJAX中Webservice调用方法示例
ASP.NET 2.0 AJAX中能够在客户端js中很方便地调用服务器Webservice，以下为一些调用的示例。笔者安装的ASP.NET 2.0 AJAX版本为AJAX November CTP。
三个示例分别为：
1 带参数的WS方法
2 不带参数的WS方法
3 参数类型为DataTable的WS方法
一、WebMethod
注意要点：
1 WebMethod类需要添加命名空间 Microsoft.Web.Script.Services，此空间需要引用Microsoft.Web.Preview.dll
2 类声明加入标签
3 在Asp.net 2.0里可以直接用DataTable作为返回类型了，但是需要在Web.config文件添加序列化转换器的属性。DataSet、DataTable、DataRow均有转换器<span style="color: red;" />WEB服务1：WS1
