c# 表單最小化到托盤

c# winform最小化到托盤,也就是最小化到右下角，其實很簡單，winform中有專門的控制項。

下面是完整的代碼，沒太多需要解釋的。

先在winform中添加notifyIcon控制項，然後啟用相應事件，添加代碼。因為屏蔽了關閉表單事件,可以設定一個全域變數bool變數來分辨是哪裡引起的close事件。

注意添加Form的SizeChanged事件和NotifyIcon控制項的DoubleClick事件

1.       //全家變數bool closeTag = true;
3.         //最小化
4.         private void form1_Resize(object sender, EventArgs e)
5.          {
6.             if (this.WindowState == FormWindowState.Minimized)
7.              {
8.                  NormalToMinimized();
9.              }           
10.          }
11.         //close時最小化
12.         private void form1_FormClosing(object sender, FormClosingEventArgs e)
13.          {
14.              e.Cancel = true;
15.              NormalToMinimized();
16.          }
17.         //單擊顯示表單
18.         private void notifyIcon_MouseClick(object sender, MouseEventArgs e)
19.          {
20.             if (e.Button == MouseButtons.Left)
21.              {
22.                 this.MinimizedToNormal();
23.              }
24.          }
25.         private void MinimizedToNormal()
26.          {
27.            this.Visible = true;
28.            this.WindowState = FormWindowState.Normal;
29.             notifyIcon.Visible = false;
31.          }
32.         private void NormalToMinimized()
33.          {
34.             this.WindowState = FormWindowState.Minimized;
35.             this.Visible = false;
36.             this.notifyIcon.Visible = true;
37.          }
38.         private void frmMain_FormClosing(object sender, FormClosingEventHandler e)
39.          {
40.             if (closeTag)
41.              {
42.                  e.Cancel = true;
43.                  NormalToMinimized();
44.              }
45.          }
46. //托盤右鍵關閉事件
47.         private void 退出XToolStripMenuItem_Click(object sender, EventArgs e)
48.          {
49.              closeTag = false;
50.              Application.Exit();
51.          }
