WinForm实现最小化到系统托盘方法实例详解

本文实例讲述了winform实现最小化到系统托盘方法。分享给大家供大家参考。具体分析如下：

有个叫notifyicon的控件

1、建个winform项目，其它操作略过。
2、拉个notifyicon控件，将属性visable设置成false，在text属性上随便填些文件。
3、实现form的sizechanged事件，代码如下：

if(this.windowstate == formwindowstate.minimized) //判断是否最小化
{
this.showintaskbar = false; //不显示在系统任务栏
notifyicon.visible = true; //托盘图标可见
}

4、实现notifyicon控件的doubleclick事件，代码如下：

if(this.windowstate == formwindowstate.minimized)
{
this.showintaskbar = true; //显示在系统任务栏
this.windowstate = formwindowstate.normal; //还原窗体
notifyicon.visible = false; //托盘图标隐藏
}

例题：

private contextmenu notifyiconmnu;
#region 最小化到任务栏
/// <summary>
/// 最小化到任务栏
/// </summary>
private void initializenotifyicon()
{
  //定义一个menuitem数组，并把此数组同时赋值给contextmenu对象 
  menuitem[] mnuitms = new menuitem[3];
  mnuitms[0] = new menuitem();
  mnuitms[0].text = "显示窗口";
  mnuitms[0].click += new system.eventhandler(this.notifyicon1_showfrom);
  mnuitms[1] = new menuitem("-");
  mnuitms[2] = new menuitem();
  mnuitms[2].text = "退出系统";
  mnuitms[2].click += new system.eventhandler(this.exitselect);
  mnuitms[2].defaultitem = true;
  notifyiconmnu = new contextmenu(mnuitms);
  notifyicon1.contextmenu = notifyiconmnu;
  //为托盘程序加入设定好的contextmenu对象 
}
private void notifyicon1_doubleclick(object sender, eventargs e)
{
  if (this.windowstate == formwindowstate.minimized)
  {
    this.show();
    this.showintaskbar = true; 
    this.windowstate = formwindowstate.normal; 
    notifyicon1.visible = false; 
  }
}
public void notifyicon1_showfrom(object sender, system.eventargs e)
{
  if (this.windowstate == formwindowstate.minimized)
  {
    this.show();
    this.showintaskbar = true;
    this.windowstate = formwindowstate.normal;
    notifyicon1.visible = false;
  }
}
public void exitselect(object sender, system.eventargs e)
{
  //隐藏托盘程序中的图标 
  notifyicon1.visible = false;
  //关闭系统 
  this.close();
  this.dispose(true);
}
#endregion
private void form_main_sizechanged(object sender, eventargs e)
{
  if (this.windowstate == formwindowstate.minimized)
  //判断是否最小化
  {
    notifyicon1.visible = true;
    this.hide();
    this.showintaskbar = false;
    initializenotifyicon();
  }
}
