vb.net如何动态调用WebService接口啊调用webservice接口
一般分为静态调用和动态调用
静态调用就是在项目中直接添加服务引用或者web服务引用服务引用vb.net；
动态调用就是通过模拟http协议调用服务引用vb.net，这种网上很多提供动态调用服务服务引用vb.net的处理类，找找直接用就可以了；
静态调用特点服务引用vb.net：服务参数包含复杂类型（比如自定义的一些实体类)用它比较方便，但是服务如果改变（服务地址更新，服务内容更新）就需要在项目中更新服务引用，重新编译程序；
动态调用特点：对于服务参数包含复杂类型的处理不是很好，如果服务内容改变不需要重新编译程序；
大致想到就这样，详细的可以在网上找找相关的网文，很多资料可以参考的
关于VB.NET添加引用的问题添加引用好像只是把引用的文件目录链接过来 ， 如果你要发到别人那里也能用 ， 就要放在你自己的工程文件包里 。
