怎么写客户端客户端要现实服务器上rg文件中的数据

WinForm? Silverlight?
最基本的是什么体系都不告诉，那就木有办法了，呵呵！

winform

这里给出一个例子，采用两种方式获取服务器上的文件数据：
1、WebClient直接下载数据或文件，这种方式要求你下载的文件必须是允许下载的（即服务器配置中你所访问的路径必须是被允许的），还有你访问的文件类型必须是已注册的（MIME类型）；
2、Web服务方式，这要求你添加Web服务引用（是你自己写的网站就可以）或者添加该服务器上已存在且公开的相关Web服务；
3、代码只是示例如何获取文件，有些细节并未考虑，如数据长度、错误捕捉以及服务的访问许可等问题，请自行实现。
