我需要编写一个Web应用程序，它允许客户端从服务器下载一个文件，到目前为止好，但文件必须是一种连接codeD，所以我需要去code这在客户端上，并将其写入在客户的个人计算机上的文件。

I need to write a web application that allows the client to download a file from the server, so far so good, but the file must be kind of encoded, so i need to decode it on the client and write it on a file on the client's PC.

我可以这样做使用Silverlight？怎么样？

Can i do this using Silverlight? and how?

如果这是不可能，有另一种方法来做到这一点？有什么建议？

If it is not possible, there is another way to do it?. Any suggestions?

感谢

编辑：暴露布赖恩Genisio，我可以要求用户permision来保存文件，所以我认为，打开和保存对话框都ok了我的情况。但是，如果说这还不够，是有办法，有或没有用户交互，将文件保存在独立存储之外，例如模拟一个新的下载用户？

As exposed for Brian Genisio, i can ask for user permision to save the file, so i think that the open and save Dialogs are ok for my case. But in case that that's not enough, is there a way to, with or without user interaction, to save the file outside of the isolated storage, for example emulating a new download for the user?

在Silverlight 3.0，你将有机会获得读写通过OpenFileDialog.在Silverlight 2.0，您可以访问隔离Sotrage，这将让您保存到沙箱中。你可能永远不会有完全访问文件系统，未经用户许可，但。

In Silverlight 3.0, you will have access to read and write files via the OpenFileDialog. In Silverlight 2.0, you have access to Isolated Sotrage, which will let you save to a sandbox. You will probably never have full access to the file system without user permission, though.
