wpf ProgressBar使用

wpf progressBar使用起来有些麻烦，直接设置value的值还不行

而是通过委托来执行setValue方法

//Create a Delegate that matches the Signature of the ProgressBar's SetValue method
private delegate void UpdateProgressBarDelegate(System.Windows.DependencyProperty dp, Object value);

private void Process()
        {
            //Configure the ProgressBar
            ProgressBar1.Minimum = 0;
            ProgressBar1.Maximum = 600;
            ProgressBar1.Value = 0;

            //Stores the value of the ProgressBar
            double value = 0;

            //Create a new instance of our ProgressBar Delegate that points
            // to the ProgressBar's SetValue method.
            UpdateProgressBarDelegate updatePbDelegate = new UpdateProgressBarDelegate(ProgressBar1.SetValue);

            //Tight Loop: Loop until the ProgressBar.Value reaches the max
            do
            {
                value += 1;
                /*Update the Value of the ProgressBar:
                  1) Pass the "updatePbDelegate" delegate that points to the ProgressBar1.SetValue method
                  2) Set the DispatcherPriority to "Background"
                  3) Pass an Object() Array containing the property to update (ProgressBar.ValueProperty) and the new value */
                Dispatcher.Invoke(updatePbDelegate,
                    System.Windows.Threading.DispatcherPriority.Background,
                    new object[] { ProgressBarEdit.ValueProperty, value });

            }
            while (ProgressBar1.Value != ProgressBar1.Maximum);
        }
