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
