WP7 弹出窗口在 thread.sleep 之前显示，但直到之后才出现
我目前正在使用 Thread.Sleep(2500) 在模拟层中模拟网络调用，直到我们可以连接到 Web 服务。我创建了一个带有进度条的弹出窗口（是的，我正在使用 Jeff Wilcox 的进度条），基于 此示例，并已成功显示弹出窗口。但是，我遇到了一个问题，即当我在使用 Thread.Sleep() 后调用弹出窗口时，弹出窗口不会加载。直到 Thread.Sleep() 返回后才会出现进度条。我正在尝试让它在即将到来的演示中工作，所以我想弄清楚如何使它与 Thread.Sleep() 一起工作，而不是等待服务并希望它在那里工作。
I'm currently using Thread.Sleep(2500) to simulate a network call in a mock layer until we can connect to the web services. I have a created a popup with a progress bar (yes, I am using Jeff Wilcox's progress bar) based on this example, and have gotten the popup to appear successfully. However, I am running into an issue where the popup doesn't load when I call it after using Thread.Sleep(). The progress bar does not appear until after Thread.Sleep() returns. I'm trying to get this working for an upcoming demo, so I'd like to figure out how to make it work with Thread.Sleep() instead of waiting for the services and hoping it works there.

您的 Thread.Sleep 正在使 UI 线程休眠，这会阻止弹出窗口在您的方法返回之前显示。您需要使用
DispatcherTimer类在经过一段TimeSpan后在 UI 线程上进行回调，或者创建一个执行睡眠操作的新线程。当您确实进行网络操作时，这是一个很好的教训：不要阻塞 UI 线程。
Your
Thread.Sleepis sleeping the UI thread which is preventing the popup from being displayed until after your method returns. You need can either use theDispatcherTimerclass to get a call back on the UI thread after someTimeSpanhas elapsed, or create a new thread which does the sleep.This is a good lesson for when you do have network operations: don't block the UI thread.
