Info

public Worker() { } // 初始化时同时指定 IWorkerReport public Worker(IWorkerReport report) { this.report = report; } // 或者初始化后 , 通过设置此属性指定 public IWorkerReport Report { set { report = value; } } public void DoLongTimeTask() { int i; bool t = false; double rate; if (report != null) { report.OnStartWork( MAX ); } for (i = 0; i
} } } 你可以运行编译好的示例 , 它可以完成和前面介绍的事件模型一样的工作 , 并保证了耦合度没有增加。调用 Worker 的 Form1 需要做一个 IWorkerReport 的实现 : private void button1_Click(object sender, System.EventArgs e) { statusBar1.Text = " 开始工作 ...."; this.Cursor = Cursors.WaitCursor; long tick = DateTime.Now.Ticks; Worker worker = new Worker(); // 指定 IWorkerReport worker.Report = new MyWorkerReport(this); worker.DoLongTimeTask(); tick = DateTime.Now.Ticks - tick; TimeSpan ts = new TimeSpan(tick); this.Cursor = Cursors.Default; statusBar1.Text = String.Format(" 任务完成 , 耗时 {0} 秒。", ts.TotalSeconds); } // 这里实现 IWorkerReport private class MyWorkerReport : IWorkerReport { public void OnStartWork(int totalUnits) { } public void OnEndWork() { } public void OnRateReport(double rate) { parent.statusBar1.Text = String.Format(" 已完成 {0:P0} ....", rate);
