我如何能实现在Silverlight中的同步调用WCF服务？ [英] How I can implement sync calls to WCF services in SIlverlight?
问题描述
有时候，我需要调用WCF服务在Silverlight并阻止用户界面，直到它返回。当然，我能做到这一点的三个步骤：
Sometimes I need to call WCF service in Silverlight and block UI until it returns. Sure I can do it in three steps:
- 设置处理程序和块UI
- 呼叫服务
- 阻止用户界面，当一切都已经完成。
不过，我想补充DoSomethingSync方法以服务客户端类，只是调用它，每当我需要的。
However, I'd like to add DoSomethingSync method to service client class and just call it whenever I need.
这可能吗？有没有人真正实施这样的方法
Is it possible? Has anyone really implemented such a method?
更新：
貌似答案是不使用同步调用的。将寻找一些易于使用的模式来异步调用。看看这职位（摘自。评论）更多
UPDATE: Looks like the answer is not to use sync calls at all. Will look for some easy to use pattern for async calls. Take a look at this post (taken from comments) for more.
推荐答案
这里的点;您不该做同步IO在Silverlight。停止战斗吧！相反：
Here's the point; you shouldn't do sync IO in Silverlight. Stop fighting it! Instead:
- 禁用UI
- 的任何关键部件开始异步IO与回调
- （...）
- 在回调，处理数据并更新/重新启用UI
- disable any critical parts of the UI
- start async IO with callback
- (...)
- in the callback, process the data and update/re-enable the UI
碰巧的是，我积极努力就如何使异步模式更加平易近人（特别是与Silverlight记）。 这里第一个尝试，但我有更好的东西我的袖子;-p
As it happens, I'm actively working on ways to make the async pattern more approachable (in particular with Silverlight in mind). Here's a first stab, but I have something better up my sleeve ;-p
