如何禁用 WebClient 和 Windows Phone 7 的缓存 [英] How do you disable caching with WebClient and Windows Phone 7

问题描述

我正在调用 REST 网络服务，而移动应用正在从其缓存中检索结果，而不是前往服务器.

I am making a call to a REST web service and the mobile app is retrieving the results from its cache and not going to the server.

我看到了其他建议的修复(类似问题和类似问题2) 但Cache 属性在silverlight 4 中不可用.

I have seen other suggested fixes (similar issue and similar issue2) but the Cache property is not available in silverlight 4.

有没有人知道如何在 Windows Phone 7 上强制 Silverlight 4 发出请求而不访问缓存?

Does anyone have an idea of how to force silverlight 4 on windows phone 7 to make a request and not hit the cache?

推荐答案

虽然不理想，但一个简单的解决方案是发送类似字段垃圾"的内容，其值为 DateTime.Now.这样，一个值总是全新的，永远不会被缓存.例如，如果您在标准查询中执行此操作:

Although not ideal, a easy solution is to send something like the field "junk" with the value DateTime.Now. That way, a value is always brand new, and will never get cached. If you were doing this in a standard querysting for example:

"&junk=" + DateTime.Now;
