在Form中增加一个Timer

private NotifyIcon notifyIcon;
private ContextMenuStrip contextMenu;
private Icon normalIcon=new Icon(@"E:\素材\蘑菇.ico");
private Icon blackIcon=new Icon(@"E:\素材\蘑菇灰.ico");
private bool status = true;
private bool blink = false;

/// <summary>

public void NotifyRightClickMenu()
{

    // 设置图标
    notifyIcon.Icon = new System.Drawing.Icon(@"E:\素材\蘑菇48.ico"); // 替换为你的图标路径
    notifyIcon.Text = "提示";
    notifyIcon.Visible = true;

    contextMenu = new ContextMenuStrip();
    var aa = new EventHandler(MenuItem_Show);
    contextMenu.Items.Add("显示", null, new EventHandler(MenuItem_Show));

    contextMenu.Items.Add("闪烁", null, new EventHandler(MenuItem_Blink));
    contextMenu.Items.Add("退出", null, new EventHandler(MenuItem_Exit));
    notifyIcon.MouseUp += NotifyIcon_MouseUp;
    //this.timer = new System.Timers.Timer();
