一 进度条的 隐藏 ，在WPF 里面
ProgressBar progressBar1=new ProgressBar();
progressBar1.Visibility= Visibility.Hidden; //隐藏
progressBar1.Visibility= Visibility.Hidden; //隐藏
progressBar1.Visibility= Visibility.Visible; //显示
二 进度条的 基本用法，在WPF 里面
progressBar1.Visibility= Visibility.Hidden; //隐藏
progressBar1.Maximum = 100; //最大值
progressBar1.Value = 3; //设置值
三 特别的用法，在一个线程里面 设置 不是本线程的 对象。
例如在一个线程里面控制进度条的 值
wpf中提供了全新的Dispatcher类。可以使用this.Dispatcher.BeginInvoke()或者控件.Dispatcher.BeginInvoke()这个方式和winform2.0是比较类似的。
