Silverlight跨线程问题解决办法

方法一：使用DependencyObject.dispatcher.BeginInvoke 方法

private void btnThread1_Click( object sender,RoutedEventArgs e)
{
new Thread(() => {
this.dispatcher.BeginInvoke(() => { MessageBox.Show( " Hello World "); });
}).Start(); } 

方法二：使用SynchronizationContext 对象

private void btnThread1_Click( object sender,RoutedEventArgs e)
{
SynchronizationContext context = SynchronizationContext.Current;
new Thread(() => { context.Post((state) => { MessageBox.Show( " Hello World "); },null); }).Start();
} 

方法三： System.Windows.Deployment

new Thread(() => {
new Thread(() => {
System.Windows.Deployment.Current.dispatcher.BeginInvoke(() => { MessageBox.Show( " Hello World "); }); 

}).Start();

 }).Start();
