C# 程序启动最小化至任务栏及闪烁

主要功能：

C#让窗体最小化至任务栏,同时在系统托盘区的图标点击左键能显示窗体，并使窗体闪烁。

首先：

创建窗体应用程序，并添加控件NotifyIcon及ContextMenuStrip控件

NotifyIcon：点击notifyIcon1属性,为控件属性Icon添加图标

contextMenuStrip1属性,进入Items添加或右键"编辑项".添加4个toolStripMenuItem,设置其Text为"显示窗体"、"隐藏窗体"、"开始闪烁"、"退出"

代码：

点击窗体"关闭"按钮时,取消关闭操作且窗体隐藏,任务栏图标仍然显示:

//窗体关闭前发生事件
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (e.CloseReason == CloseReason.UserClosing)
{
e.Cancel = true;           //取消关闭操作 表现为不关闭窗体
this.Hide();               //隐藏窗体
}
}

1.左键点击图标时,显示窗体.
2.当鼠标右键点击图标时,显示"显示窗体"\"隐藏窗体"\"闪烁"\"退出"菜单栏,并有相对应的功能

//"显示窗体"单击事件
private void 显示ToolStripMenuItem_Click(object sender, EventArgs e)
{
this.Show();                                //窗体显示
this.WindowState = FormWindowState.Normal;  //窗体状态默认大小
this.Activate();
}
//"隐藏窗体"单击事件
private void 隐藏ToolStripMenuItem_Click(object sender, EventArgs e)
{
this.Hide();                      //隐藏窗体
}
//"退出"单击事件
private void 退出ToolStripMenuItem_Click(object sender, EventArgs e)
{
//点击"是(YES)"退出程序
if (MessageBox.Show("确定要退出程序?", "安全提示",
System.Windows.Forms.MessageBoxButtons.YesNo,
System.Windows.Forms.MessageBoxIcon.Warning)
== System.Windows.Forms.DialogResult.Yes)
{
notifyIcon1.Visible = false;   //设置图标不可见
this.Close();                  //关闭窗体
this.Dispose();                //释放资源
Application.Exit();            //关闭应用程序窗体
}
}

鼠标左键图标显示窗体功能

//鼠标左键图标事件
private void notifyIcon1_MouseClick(object sender, MouseEventArgs e)
{
//点击鼠标"左键"发生
if (e.Button == MouseButtons.Left)
{
this.Visible = true;                        //窗体可见
this.WindowState = FormWindowState.Normal;  //窗体默认大小
this.notifyIcon1.Visible = true;            //设置图标可见
}
}

图标闪烁

闪烁的效果是加上一个空白的图标，正常图标与空白图标的切换进而实现闪烁的效果。

property是vs的一个资源管理功能，可以存储系统图标及一些常量

private Icon timg = Properties.Resources.timg;
private Icon blank = Properties.Resources.blank;//透明的图标
private bool _status = true;
private bool _isBlink = false;

右键菜单控制图标是不是显示

private void toolStripMenuItem1_Click(object sender, EventArgs e)
{
if (_isBlink == false)
{
_isBlink = true;
timer1.Enabled = true;
timer1.Start();
}
else
{
_isBlink = false;
timer1.Stop();
//气泡提示
notifyIcon1.ShowBalloonTip(5000, "提示", "关闭闪烁效果！", ToolTipIcon.Info);
}
}

定时器中修改图标的状态，定时反转图标

private void timer1_Tick(object sender, EventArgs e)
{

if (_status)
notifyIcon1.Icon = timg;
else
notifyIcon1.Icon = blank;

_status = !_status;
}

完整代码：

public partial class Form1 : Form
{
private Icon timg = Properties.Resources.timg;
private Icon blank = Properties.Resources.blank;//透明的图标
private bool _status = true;
private bool _isBlink = false;
public Form1()
{
InitializeComponent();
}

//窗体关闭前发生事件
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (e.CloseReason == CloseReason.UserClosing)
{
e.Cancel = true;           //取消关闭操作 表现为不关闭窗体
this.Hide();               //隐藏窗体
}
}
//"显示窗体"单击事件
private void 显示ToolStripMenuItem_Click(object sender, EventArgs e)
{
this.Show();                                //窗体显示
this.WindowState = FormWindowState.Normal;  //窗体状态默认大小
this.Activate();
}
//"隐藏窗体"单击事件
private void 隐藏ToolStripMenuItem_Click(object sender, EventArgs e)
{
this.Hide();                      //隐藏窗体
}
//"退出"单击事件
private void 退出ToolStripMenuItem_Click(object sender, EventArgs e)
{
//点击"是(YES)"退出程序
if (MessageBox.Show("确定要退出程序?", "安全提示",
System.Windows.Forms.MessageBoxButtons.YesNo,
System.Windows.Forms.MessageBoxIcon.Warning)
== System.Windows.Forms.DialogResult.Yes)
{
notifyIcon1.Visible = false;   //设置图标不可见
this.Close();                  //关闭窗体
this.Dispose();                //释放资源
Application.Exit();            //关闭应用程序窗体
}
}
//鼠标左键图标事件
private void notifyIcon1_MouseClick(object sender, MouseEventArgs e)
{
//点击鼠标"左键"发生
if (e.Button == MouseButtons.Left)
{
this.Visible = true;                        //窗体可见
this.WindowState = FormWindowState.Normal;  //窗体默认大小
this.notifyIcon1.Visible = true;            //设置图标可见
}
}

private void toolStripMenuItem1_Click(object sender, EventArgs e)
{
if (_isBlink == false)
{
_isBlink = true;
timer1.Enabled = true;
timer1.Start();
}
else
{
_isBlink = false;
timer1.Stop();
//气泡提示
notifyIcon1.ShowBalloonTip(5000, "提示", "关闭闪烁效果！", ToolTipIcon.Info);
}
}
private void timer1_Tick(object sender, EventArgs e)
{

if (_status)
notifyIcon1.Icon = timg;
else
notifyIcon1.Icon = blank;

_status = !_status;
}
