利用web service 生产xml文件
我用下面的代码在本机测试能够生成xml文件，返回"Y".但是我把Web service放在服务器上返回的是"N".我的服务器是windows2008,IIS 7.0 请大家帮忙看下是什么原因引起的。--------------------编程问答-------------------- 你可以直接调试跟踪一嘛 --------------------编程问答-------------------- 明显是目录没权限啊，iis要对访问的目录赋予权限。。。

另外建议你用 HttpContext.Current.Server.MapPath("~/XXX") 这样把路径放到 WebService 所在目录的子目录里。注意安全啊
补充：.NET技术 , Web Services
