C#窗体的最大化/最小化/还原/最小化到托盘/NotifyIcon的代码实现

1.最小化

WindowState = FormWindowState.Minimized;

//最小化时隐藏窗体

this.Visible=false;

2.最大化

WindowState == FormWindowState.Maximized;

3.还原为正常

WindowState == FormWindowState.Normal;

4.在托盘显示

   打开 VS.net的工具箱,然后选择NotifyIcon,拖到Form上,在属性中Icon中设置图象添加一个ContextMenu,输入需要的选择项在 NotifyIcon中的ContextMenu属性中可以设置刚添加的ContextMenu 点托盘上的图标 就可以显示选择项  

实例部分代码:

              #region 还原窗体

              private void normalForm()
              {
                  //this.AutoScaleBaseSize = new System.Drawing.Size(5, 15);
                  //this.ClientSize = new System.Drawing.Size(504, 267);
                  this.Visible = true;
                  //this.WindowState=FormWindowState.Normal;
              }
              #endregion

           #region 最小化窗体并在托盘显示,隐藏窗体
           private void minForm()
           {
               WindowState = FormWindowState.Minimized;
               this.Visible = false;
               this.notifyIconCMPC.Visible = true;
               this.myTimer.Enabled = false;
               //this.Hide();
               //设置气球状工具提示显示的时间为10秒
               this.notifyIconCMPC.ShowBalloonTip(30);
           }
           #endregion

              #region         重写WndProc屏蔽掉关闭按钮
              protected override void WndProc(ref Message m)
              {
                  const int WM_SYSCOMMAND = 0x0112;
                  const int SC_CLOSE = 0xF060;
                  if (m.Msg == WM_SYSCOMMAND && (int)m.WParam == SC_CLOSE)
                  {
                     this.Visible = false;
                     return;
                  }
                  base.WndProc(ref m);
              }
              #endregion

           private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
           {
               if (this.WindowState == FormWindowState.Minimized || this.Visible == false)
               {
                   this.normalForm();
               }
               else
               {
                   minForm();
               }
           }
