第一步:如何在线程中打开窗体
SendEmailProgress progress=new SendEmailProgress(); //添加窗体关闭事件 progress.Closing += (s, ev) => { if (progress.IsEnabledCloseForm) { } else { ev.Cancel = true;//关闭窗体 } }; Control.CheckForIllegalCrossThreadCalls = false; //在这个类中我们不检查跨线程的调用是否合法 Thread thread = new Thread(new ParameterizedThreadStart(ShowCommonProgressFormDialog)); thread.Start(); if (isFirst) { Thread.Sleep(5000); isFirst = false; } progress.WriteMessage("","","");// private static void ShowCommonProgressFormDialog(object message) { try { int num = (int)progress.ShowDialog(); } catch (Exception) { } }
第二步:调用窗体内的方法。
private delegate void WriteMessageHandler(string message, EnumColorInts eci, bool isNeedSetSize); /// <summary> /// 显示提示消息 /// </summary> /// <param name="message"></param> /// <param name="eci"></param> private void WriteMessage(string message, EnumColorInts eci,bool isNeedSetSize) { Font font = new Font(FontFamily.GenericMonospace, 14, FontStyle.Regular); //如果控件的 System.Windows.Forms.Control.Handle 是在与调用线程不同的线程上创建的(说明您必须通过 Invoke //方法对控件进行调用),则为 true;否则为 false。 //(备注:获取一个值,该值指示调用方在对控件进行方法调用时是否必须调用 Invoke 方法,因为调用方位于创建控件所在的线程以外的线程中。) if (InvokeRequired) { WriteMessageHandler handler = WriteMessage; Invoke(handler, new object[] { message, eci, isNeedSetSize }); } else { int index = RtMessageBox.Text.Length; RtMessageBox.AppendText(message); RtMessageBox.Select(index, message.Length); else { switch (eci) { case EnumColorInts.Red: RtMessageBox.SelectionColor = Color.Red; break; case EnumColorInts.Green: RtMessageBox.SelectionColor = Color.Green; break; case EnumColorInts.Black: default: RtMessageBox.SelectionColor = Color.Black; break; } } RtMessageBox.AppendText(" "); RtMessageBox.SelectionStart = RtMessageBox.Text.Length; RtMessageBox.ScrollToCaret(); } }
以上仅作为个人学习积累。。。。。。
