c# winform最小化到托盘

       先在winform中添加notifyIcon控件，然后激活相应事件，添加代码。因为屏蔽了关闭窗体事件,可以设定一个全局变量bool变量来分辨是哪里引起的close事件。

1.       //全家变量bool closeTag = true;
2.         //最小化 
3.         private void form1_Resize(object sender, EventArgs e)
4.         {
5.             if (this.WindowState == FormWindowState.Minimized)
6.             {
7.                 NormalToMinimized();
8.             }           
9.         }
10.         //close时最小化 
11.         private void form1_FormClosing(object sender, FormClosingEventArgs e)
12.         {
13.             e.Cancel = true;
14.             NormalToMinimized();
15.         }
16.         //单击显示窗体
17.         private void notifyIcon_MouseClick(object sender, MouseEventArgs e)
18.         {
19.             if (e.Button == MouseButtons.Left)
20.             {
21.                 this.MinimizedToNormal();
22.             }
23.         }
24.         private void MinimizedToNormal()
25.         {
26.            this.Visible = true;
27.            this.WindowState = FormWindowState.Normal;
28.            notifyIcon.Visible = false;
29.         }
30.         private void NormalToMinimized()
31.         {
32.             this.WindowState = FormWindowState.Minimized;
33.             this.Visible = false;
34.             this.notifyIcon.Visible = true;
35.         }
36.         private void frmMain_FormClosing(object sender, FormClosingEventHandler e)
37.         {
38.             if (closeTag)
39.             {
40.                 e.Cancel = true;
41.                 NormalToMinimized();
42.             }
43.         }
44. //托盘右键关闭事件
45.         private void 退出XToolStripMenuItem_Click(object sender, EventArgs e)
46.         {
47.             closeTag = false;
48.             Application.Exit();
49.         }
