wpf线程进度控制

先上源码：

namespace touchPy.Loading{public class MyLoading{public static readonly MyLoading Instance = new MyLoading();private ScheduleBarWindow _mld;//loading对象Thread _newWindowThread;//loading线程object obj = new object();bool isStart = false;private MyLoading(){}#region 载入loading控件/// <summary>/// 载入loading控件/// </summary>public void LoadingStart(){isStart = true;_newWindowThread = new Thread(new ThreadStart(Loading));_newWindowThread.SetApartmentState(ApartmentState.STA);_newWindowThread.IsBackground = true;_newWindowThread.Start();//threadLst.Add(_newWindowThread);}#endregion#region 线程载入函数private void Loading(){_mld = new ScheduleBarWindow();_mld.ShowDialog();//System.Windows.Threading.Dispatcher.Run();}#endregion#region 结束线程，关闭loading/// <summary>/// 结束线程，关闭loading/// </summary>public void LoadingEnd(){if(isStart){while (_mld == null){Thread.Sleep(10);}_mld.Dispatcher.BeginInvokeShutdown(DispatcherPriority.Normal);_newWindowThread.Abort();isStart = false;}}#endregion#region 结束线程，关闭loading/// <summary>/// 结束线程，关闭loading/// </summary>public void LoadingEnd(UCTreeView _treeView){Thread _WindowThread = new Thread(LoadingHalt);_WindowThread.SetApartmentState(ApartmentState.STA);_WindowThread.IsBackground = true;_WindowThread.Start(_treeView);}#endregionvoid LoadingHalt(object data){if (isStart){UCTreeView _tree = data as UCTreeView;bool bFlag = (bool)_tree.Dispatcher.Invoke(new Func<bool>(()=>{return _tree.IsLoaded;}), null);while (_mld == null || !bFlag){bFlag = (bool)_tree.Dispatcher.Invoke(new Func<bool>(() =>{return _tree.IsLoaded;}), null);Thread.Sleep(10);}_mld.Dispatcher.BeginInvokeShutdown(DispatcherPriority.Normal);_newWindowThread.Abort();isStart = false;}}}}

C#线程为单线程模式，所有界面资源线程之间不能共享，对于主线程中后台代码业务处理比较耗时的情况下，需要添加新的线程处理另外一些界面效果。

IsLoad属性，作为界面数据使用数据绑定方式产生延迟的返回结果，告诉用为前台渲染效果是否完成，是否取消ScheduleBarWindow等待加载窗口提示的显示。

Dispatcher.BeginInvokeShutdown关闭消息泵的处理流程，同时关闭了显示窗口。
