mono webservice问题请教
各位大神，最近在学习mono for android 在vs2010里面调用webservice的项目，目前项目中直接添加web引用是可以正常使用的。但实际运用中，webservice地址有可能会变化，想请教下，如何动态调用webservice。
网上查了常见的几种c#调用webservice方法都不可以使用。查看了mono的system.dll基础类库和framework的system.dll的基础类库不一样，删减了很多，缺少CodeNamespace等。请教论坛里各位大神，看有没有什么方法能解决。感谢 webservice mono android
