C#教程：MouseClick和MouseDoubleClick事件使用实例
MouseClick和MouseDoubleClick事件1．MouseClick事件该事件发生于单击控件时。语法:public event EventHandler MouseClick参数说明如下。EventHandler：表示将处理不包含事件数据的事件的方法。示例MouseClick事件的使用在窗体中单击任何地方，触发MouseClick事件，在事件中起动timer控件，将窗体标题变成一个时钟。示例运行结果如图1所示。图1 MouseClick事件的使用private void frmMouseClick_MouseClick(object sender, MouseEventArgs e){this.timer1.Enabled = True;}完整程序代码如下：★ ★★★★frmMouseClick.cs窗体代码文件完整程序代码★★★★★using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.Windows.Forms;namespace _2_04{public partial class frmMouseClick : Form{public frmMouseClick(){InitializeComponent();}private void frmMouseClick_MouseClick(object sender, MouseEventArgs e){this.timer1.Enabled = true;}private void frmMouseClick_MouseDoubleClick(object sender, MouseEventArgs e){}private void timer1_Tick(object sender, EventArgs e){this.Text = "现在时间" + DateTime.Now.ToString();}private void frmMouseClick_Load(object sender, EventArgs e){}}}★ ★★★★frmMouseClick.Designer.cs窗体设计文件完整程序代码★★★★★namespace _2_04{partial class frmMouseClick{/// /// 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();this.timer1 = new System.Windows.Forms.Timer(this.components);this.SuspendLayout();//// timer1//this.timer1.Interval = 1000;this.timer1.Tick += new System.EventHandler(this.timer1_Tick);//// frmMouseClick//this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;this.ClientSize = new System.Drawing.Size(451, 145);this.Name = "frmMouseClick";this.Text = "frmMouseClick";this.MouseDoubleClick += new System.Windows.Forms.MouseEventHandler(this.frmMouseClick_MouseDoubleClick);this.MouseClick += new System.Windows.Forms.MouseEventHandler(this.frmMouseClick_MouseClick);this.Load += new System.EventHandler(this.frmMouseClick_Load);this.ResumeLayout(false);}#endregionprivate System.Windows.Forms.Timer timer1;}}★ ★★★★Program.cs主程序文件完整程序代码★★★★★using System;using System.Collections.Generic;using System.Windows.Forms;namespace _2_04{static class Program{/// /// 应用程序的主入口点。/// [STAThread]static void Main(){Application.EnableVisualStyles();Application.SetCompatibleTextRenderingDefault(false);Application.Run(new frmMouseClick());}}}2．MouseDoubleClick事件该事件发生于双击控件时。语法:public event EventHandler MouseDoubleClick示例MouseDoubleClick事件双击窗体中的任何地方，触发MouseDoubleClick事件，在该事件中停止Timer控件。private void frmMouseClick_MouseDoubleClick(object sender, MouseEventArgs e){this.timer1.Enabled = False;}完整程序代码如下：★ ★★★★frmMouseClick.cs窗体代码文件完整程序代码★★★★★
