wpf中的进度条

今天学了一下进度条很简单有专门的控件progressbar能够解决这个问题，

xaml里面添加该控件

cs里面可以添加

private void beginImport()
{
double value = 0;
double total = 100d;//得到循环次数
while (value < total)
{
double jd = Math.Round(((value + 1) * (pb_import.Maximum / total)), 4);

pb_import.Dispatcher.Invoke(new Action<System.Windows.DependencyProperty, object>(pb_import.SetValue),
System.Windows.Threading.DispatcherPriority.Background,
ProgressBar.ValueProperty,
jd);
//这里是加数据或费时的操作，我这里让它挂起300毫秒
Thread.Sleep(30);
//txtJD.Text = "当前的进度是:" + (value + 1) + "(实际值)" + jd + "(百分比)";
value++;
}
}

如何觉得控件不够好看，也可修改样式，我修改的不是很好看！
