实现托盘（任务栏图标与托盘图标互斥），并且在点击任务栏图标时实现的最小化与点击最小化按钮分离。
具体如下：
1、向窗体上添加如下控件：MenuStrip menuStrip1, NotifyIcon ni_frmMain,Timer timer1, ContentMenuStrip cms_notify。其中notify中包含显示、退出等。
2、实现的代码：
//字段：
//当前子Form
private CurrentForm childForm = null; //上次窗体的状态
private FormWindowState lastFormState; //是否点击的是最小化按钮
private bool isMinBoxHited; //构造函数内
this.ni_frmMain.Visible = false; #region 托盘相关代码 #region 私有方法 处理窗体的 显示 隐藏 关闭(退出) /// <summary>
/// 显示
/// </summary>
private void ShowMainForm()
{
this.Show();
this.WindowState = this.lastFormState;
this.Activate(); this.ShowInTaskbar = true; //任务栏中显示窗体图标
this.ni_frmMain.Visible = false;//图盘中隐藏图标
} /// <summary>
/// 隐藏
/// </summary>
private void HideMainForm()
{
this.Hide(); this.ShowInTaskbar = false; //任务栏中显示窗体图标
this.ni_frmMain.Visible = true;//图盘中隐藏图标
} /// <summary>
/// 关闭(退出)
/// </summary>
private void ExitMainForm()
{
if (MessageBox.Show("您确定要退出主程序吗？", "确认退出", MessageBoxButtons.OKCancel, MessageBoxIcon.Question, MessageBoxDefaultButton.Button2) == DialogResult.OK)
{
this.ni_frmMain.Visible = false;
this.Close();
this.Dispose();
Application.Exit();
}
