如何在 Silverlight 中编写每 10 秒执行一次操作的程序？
如何在 Silverlight 中编写每 10 秒执行一次操作的程序，例如处理 twitter 搜索结果？我最接近的是：
// Get and process new twitter search results evey 10 seconds
BackgroundWorker worker = new BackgroundWorker();
worker.DoWork += (sender, args) =>
{
while (true)
{
//Get results of Twitter Search and process them in the above code
client.DownloadStringAsync(new Uri("http://search.twitter.com/search.json?q=" + keywords + "&show-user=true", UriKind.Absolute));
// wait 10 seconds beofre getting new twits
System.Threading.Thread.Sleep(10000);
}
};
worker.RunWorkerAsync();
但它不起作用。请帮忙。

如果您希望代码在UI线程上执行，则需要DispatcherTimer。请参阅此帖子。
If you want the code to be excuted on the UI thread, you need
DispatcherTimer. See this post.您想要使用
System.Threading.Timer。底部带有示例代码的所有官方文档： http:// msdn.microsoft.com/en-us/library/system.threading.timer.aspxYou want to use
