Winforms中使用系统托盘图标

1.在form窗体中拖入notifyIcon控件。

2.设置控件的text属性和指定ICO图标文件。

3.运行程序，发现右下角的出现了系统托盘。

更多技巧：

1.添加右键菜单：

在窗体上拖入contextMenuStrip控件，设置notifyIcon控件的contextMenuStrip属性名称为拖入的contextMenuStrip控件名称。

2.窗口关闭时窗口隐藏，通过右键菜单显示和关闭：

代码如下：

设置窗口的关闭为隐藏：

   1: bool isClose = false;//设置标示 标示窗口是否真正关闭

   2:       private void Form5_FormClosing(object sender, FormClosingEventArgs e)

   3:       {

   4:           //如果不是真正关闭 则取消关闭事件 讲窗体设置为隐藏

   5:           if (!isClose)

   6:           {

   7:               e.Cancel = true; 

   8:               this.Visible = false;

   9:           }

  10:       }

使用托盘的右键菜单关闭窗体：

   1: /// <summary>

   2: // 托盘的右键关闭菜单 真正关闭窗体

   3: /// </summary>

   4: /// <param name="sender"></param>

   5: /// <param name="e"></param>

   6: private void 关闭ToolStripMenuItem_Click(object sender, EventArgs e)

   7: {

   8:     

   9:     isClose = true;

  10:     Application.Exit();

  11: }

使用托盘的右键菜单显示隐藏的窗体：

   1: /// <summary>

   2: // 托盘的右键显示菜单 显示隐藏的窗体

   3: // </summary>

   4: // <param name="sender"></param>

   5: // <param name="e"></param>

   6: rivate void 显示ToolStripMenuItem_Click(object sender, EventArgs e)

   7:  

   8:    this.Visible = true;

3.窗口最小化到系统托盘上

使用窗体SizeChanged事件隐藏窗体：

   1: /// <summary>

   2: /// 设置系统状态为最小化的时候 窗体隐藏  注意使用的SizeChanged事件

   3: /// </summary>

   4: /// <param name="sender"></param>

   5: /// <param name="e"></param>

   6: private void Form5_SizeChanged(object sender, EventArgs e)

   7: {

   8:     //判断状态为最小化状态时隐藏窗体

   9:     if (this.WindowState == FormWindowState.Minimized)

  10:     {

  11:         this.Visible = false;

  12:     }

  13: }

使用托盘右键菜单显示隐藏的窗体，并设置窗体的显示方式为正常状态：

   1: /// <summary>

   2: // 托盘的右键显示菜单 显示隐藏的窗体

   3: // </summary>

   4: // <param name="sender"></param>

   5: // <param name="e"></param>

   6: rivate void 显示ToolStripMenuItem_Click(object sender, EventArgs e)

   7:  

   8:    this.Visible = true;

   9:    this.WindowState = FormWindowState.Normal;//设置显示状态为正常状态

4.双击系统托盘图标显示和隐藏窗体

使用notifyIcon控件的DoubleClick事件:

   1: /// <summary>

   2: /// notifyIcon控件的DoubleClick事件 

   3: /// </summary>

   4: /// <param name="sender"></param>

   5: /// <param name="e"></param>

   6: private void notifyIcon1_DoubleClick(object sender, EventArgs e)

   7: {

   8:     bool isShow = this.Visible == true ? false : true;

   9:     this.Visible = isShow;

  10: }

全部代码如下：

   1: using System;

   2: using System.Collections.Generic;

   3: using System.ComponentModel;

   4: using System.Data;

   5: using System.Drawing;

   6: using System.Linq;

   7: using System.Text;

   8: using System.Windows.Forms;

   9:  

  10: namespace TestApp

  11: {

  12:     /// <summary>

  17:     public partial class Form5 : Form

  18:     {

  19:         public Form5()

  20:         {

  21:             InitializeComponent();

  22:         }

  23:  

  24:         private void Form5_Load(object sender, EventArgs e)

  25:         {

  26:  

  27:         }

  28:         bool isClose = false;//设置标示 标示窗口是否真正关闭

  29:         private void Form5_FormClosing(object sender, FormClosingEventArgs e)

  30:         {

  31:             //如果不是真正关闭 则取消关闭事件 讲窗体设置为隐藏

  32:             if (!isClose)

  33:             {

  34:                 e.Cancel = true; 

  35:                 this.Visible = false;

  36:             }

  37:         }

  56:         {

  58:             this.WindowState = FormWindowState.Normal;//设置显示状态为正常状态

  59:         }

  60:  

  61:         /// <summary>

  62:         /// 设置系统状态为最小化的时候 窗体隐藏  注意使用的SizeChanged事件

  64:         /// <param name="sender"></param>

  65:         /// <param name="e"></param>

  66:         private void Form5_SizeChanged(object sender, EventArgs e)

  67:         {

  68:             //判断状态为最小化状态时隐藏窗体

  69:             if (this.WindowState == FormWindowState.Minimized)

  70:             {

  71:                 this.Visible = false;

  72:             }

  73:         }

  86: }

The End!
