C#编写最小化时隐藏为任务栏图标的Window appllication.
C#编写最小化时隐藏为任务栏图标的 Window appllication.
1.设置WinForm窗体属性showinTask=false
2.加notifyicon控件notifyIcon1，为控件notifyIcon1的属性Icon添加一个icon图标。
3.添加窗体最小化事件(首先需要添加事件引用)：
this.SizeChanged += new System.EventHandler(this.Form1_SizeChanged);
//上面一行是主窗体InitializeComponent()方法中需要添加的引用
private void Form1_SizeChanged(object sender, EventArgs e)
{
if(this.WindowState == FormWindowState.Minimized)
{
this.Hide();
this.notifyIcon1.Visible=true;
}
}
4.添加点击图标事件(首先需要添加事件引用)：
private void notifyIcon1_Click(object sender, EventArgs e)
{
this.Visible = true;
this.WindowState = FormWindowState.Normal;
this.notifyIcon1.Visible = false;
}
5.可以给notifyIcon添加右键菜单：
主窗体中拖入一个ContextMenu控件NicontextMenu，点中控件，在上下文菜单中添加菜单，notifyIcon1的ContextMenu行为中选中NicontextMenu 作为上下文菜单。
this.notifyIcon1 = new System.Windows.Forms.NotifyIcon(this.components);
this.NicontextMenu = new System.Windows.Forms.ContextMenu();
this.menuItem_Hide = new System.Windows.Forms.MenuItem();
this.menuItem_Show = new System.Windows.Forms.MenuItem();
this.menuItem_Aubot = new System.Windows.Forms.MenuItem();
this.menuItem_Exit = new System.Windows.Forms.MenuItem();
this.notifyIcon1.ContextMenu = this.NicontextMenu;
this.notifyIcon1.Icon = ((System.Drawing.Icon)(resources.GetObject( "NotifyIcon.Icon ")));
this.notifyIcon1.Text = " ";
this.notifyIcon1.Visible = true;
this.notifyIcon1.DoubleClick += new System.EventHandler(this.notifyIcon1_DoubleClick);
this.notifyIcon1.Click += new System.EventHandler(this.notifyIcon1_Click);
this.NicontextMenu.MenuItems.AddRange(
new System.Windows.Forms.MenuItem[]
{
this.menuItem_Hide,
this.menuItem_Show,
this.menuItem_Aubot,
this.menuItem_Exit
}
);
//
// menuItem_Hide
//
this.menuItem_Hide.Index = 0;
this.menuItem_Hide.Text = "隐藏 ";
this.menuItem_Hide.Click += new System.EventHandler(this.menuItem_Hide_Click);
//
// menuItem_Show
//
this.menuItem_Show.Index = 1;
this.menuItem_Show.Text = "显示 ";
this.menuItem_Show.Click += new System.EventHandler(this.menuItem_Show_Click);
//
// menuItem_Aubot
//
this.menuItem_Aubot.Index = 2;
this.menuItem_Aubot.Text = "关于 ";
this.menuItem_Aubot.Click += new System.EventHandler(this.menuItem_Aubot_Click);
//
// menuItem_Exit
//
this.menuItem_Exit.Index = 3;
this.menuItem_Exit.Text = "退出 ";
this.menuItem_Exit.Click += new System.EventHandler(this.menuItem_Exit_Click);
protected override void OnClosing(CancelEventArgs e)
{
this.ShowInTaskbar = false;
this.WindowState = FormWindowState.Minimized;
e.Cancel = true;
}
protected override void OnClosing(CancelEventArgs e)
{
//this.ShowInTaskbar = false;
this.WindowState = FormWindowState.Minimized;
e.Cancel = true;
}
private void CloseCtiServer()
{
timer.Enabled = false;
DJ160API.DisableCard();
this.NotifyIcon.Visible = false;
this.Close();
this.Dispose();
Application.Exit();
}
private void HideCtiServer()
{
this.Hide();
}
private void ShowCtiServer()
{
this.Show();
this.WindowState = FormWindowState.Normal;
this.Activate();
}
private void CtiManiForm_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
this.CloseCtiServer();
}
private void menuItem_Show_Click(object sender, System.EventArgs e)
{
this.ShowCtiServer();
}
private void menuItem_Aubot_Click(object sender, System.EventArgs e)
{
}
private void menuItem_Exit_Click(object sender, System.EventArgs e)
{
this.CloseCtiServer();
}
private void menuItem_Hide_Click(object sender, System.EventArgs e)
{
this.HideCtiServer();
}
private void CtiManiForm_SizeChanged(object sender, System.EventArgs e)
{
if(this.WindowState == FormWindowState.Minimized)
{
this.HideCtiServer();
}
}
private void notifyIcon1_DoubleClick(object sender,System.EventArgs e)
{
this.ShowCtiServer();
}
1.加notifyicon控件notifyIcon1，为控件notifyIcon1的属性Icon添加一个icon图标。
this.ShowInTaskbar = false//不在任务栏中显示图标
2.加载form的SizeChanged事件.
3.加载notifyicon的单击事件:
#region 系统托盘 /// <summary> /// 单击任务栏图标显示或隐藏主面板 /// </summary> /// <param name="sender">The source of the event.</param> /// <param name="e">The <see cref="System.EventArgs"/> instance containing the event data.</param> private void notifyIcon_Click(object sender, EventArgs e) { //已显示则让它显示在最上面 if (this.Visible) this.TopMost = true; else this.Visible = true; this.WindowState = FormWindowState.Normal; this.TopMost = false; } /// <summary> /// Handles the FormClosing event of the frmMain control. /// </summary> /// <param name="sender">The source of the event.</param> /// <param name="e">The <see cref="System.Windows.Forms.FormClosingEventArgs"/> instance containing the event data.</param> private void frmMain_FormClosing(object sender, FormClosingEventArgs e) { //不是退出程序则到系统托盘 if (!isExited) { e.Cancel = true; this.Visible = false; } } /// <summary> /// 点击最小化时到系统托盘 /// </summary> /// <param name="sender">The source of the event.</param> /// <param name="e">The <see cref="System.EventArgs"/> instance containing the event data.</param> private void frmMain_SizeChanged(object sender, EventArgs e) { if (this.WindowState == FormWindowState.Minimized) { this.Visible = false; } } #endregion
题记：在编写程序历程中,创造C#还是对比人性化的,至少我是这么觉得的,今天给大家带来的是"C# 点击关闭按钮后最小化到系统 托盘" 这是在编写程序中新手经常遇到的问题,今天我就把我的法子 献给大家,请关注我们蒂强网络
法子 ：
第一步：现在窗体上加上“NotifyIcon”控件，在该控件的”Icon“属性中设置好在系统 托盘中要显示度图标。
第二步：在“NotifyIcon”控件DoubleClick事件中下如下代码
if (this.WindowState == FormWindowState.Minimized) //确定
//窗体是不是最小化
this.WindowState = FormWindowState.Normal; //如果是最小化就把窗体状态
//改为默认大小
this.Activate(); //激活窗体并赋予焦点，这句话可以不写
this.ShowInTaskbar = true; //在Windows任务栏中显示窗体。
第三步：在窗体的FormClosing事件中写如下代码：
e.Cancel = true; //取缔
//窗体关闭事件
this.WindowState = FormWindowState.Minimized; //最小化窗口
this.ShowInTaskbar = false; //在Windows任务栏中不显示窗体
取缔了窗体关闭事件就得给NotifyIcon添加右键菜单，这样可以方便退出程序；
法子 ：在SizeChanged事件中写 this.ShowInTaskbar = false; 这样就可以实现点击关闭按钮和最小化按钮时，窗体在系统 托盘中显示了。
