C#中NotifyIcon控件应用实例
NotifyIcon控件1.功能NotifyIcon控件通常用于显示在后台运行的进程的图标，这些进程大部分时间不显示用户界面。每个NotifyIcon控件都在状态栏区域显示一个图标。如果有3个后台进程，并希望为每个后台进程各显示一个图标，则需要添加3个NotifyIcon控件。图1所示为NotifyIcon控件。图1 NotifyIcon控件2．属性NotifyIcon控件常用属性及说明如表1所示。表1 NotifyIcon控件常用属性及说明下面对比较重要的属性进行详细介绍。（1）Visible属性。语法：public bool Visible { get; set; }属性值：如果图标在通知区域中可见，则为True；否则为False。默认值为False。（2）BalloonTipIcon属性。语法：public ToolTipIcon BalloonTipIcon { get; set; }属性值：要显示在与NotifyIcon关联的气球提示上的ToolTipIcon。示例BalloonTipIcon属性设置本示例中，当程序运行时，在窗体中单击鼠标右键，弹出一个“退出”快捷菜单，同时在状态栏中显示一个小人图标。示例运行结果如图2所示。图2 BalloonTipIcon属性效果程序主要代码如下：notifyIcon1.Visible = True;完整程序代码如下：★★★★★主程序文件完整程序代码★★★★★using System;using System.Collections.Generic;using System.Windows.Forms;namespace _8_12{static class Program{/// /// 应用程序的主入口点。/// [STAThread]static void Main(){Application.EnableVisualStyles();Application.SetCompatibleTextRenderingDefault(false);Application.Run(new frmNotifyIcon());}}}★★★★★frmNotifyIcon窗体设计文件完整程序代码★★★★★using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;namespace _8_12{public partial class frmNotifyIcon : Form{public frmNotifyIcon(){InitializeComponent();}private void frmNotifyIcon_Load(object sender, EventArgs e){notifyIcon1.Visible = true;}private void notifyIcon1_DoubleClick(object sender, EventArgs e){}private void 退出EToolStripMenuItem_Click(object sender, EventArgs e){Application.Exit();}}}★★★★★frmNotifyIcon窗体代码文件完整程序代码★★★★★namespace _8_12{partial class frmNotifyIcon{/// /// 必需的设计器变量。/// private System.ComponentModel.IContainer components = null;/// /// 清理所有正在使用的资源。/// /// 如果应释放托管资源，为 true；否则为 false。protected override void Dispose(bool disposing){if (disposing && (components != null)){components.Dispose();}base.Dispose(disposing);}#region Windows 窗体设计器生成的代码/// /// 设计器支持所需的方法 - 不要/// 使用代码编辑器修改此方法的内容。/// private void InitializeComponent(){this.components = new System.ComponentModel.Container();System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(frmNotifyIcon));this.notifyIcon1 = new System.Windows.Forms.NotifyIcon(this.components);this.contextMenuStrip1 = new System.Windows.Forms.ContextMenuStrip(this.components);this.退出EToolStripMenuItem = new System.Windows.Forms.ToolStripMenuItem();this.label1 = new System.Windows.Forms.Label();this.contextMenuStrip1.SuspendLayout();this.SuspendLayout();//// notifyIcon1//this.notifyIcon1.ContextMenuStrip = this.contextMenuStrip1;
