C#系统托盘程序

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;
}
