C#教程:删除线程
删除线程线程的Abort方法用于永久地停止托管线程。调用Abort方法时,公共语言运行库在目标线程中引发ThreadAbortException,目标线程可捕捉此异常。一旦线程被中止,它将无法重新启动。如果在应用程序中使用了多线程,辅助线程还没有执行完毕,在关闭窗体的时候必须要关闭辅助线程,否则会引发异常。示例线程的删除下面的代码实现了删除线程t的功能。namespace ThreadTest{public partial class Form1 : Form{private Thread t = null;public Form1(){InitializeComponent();}private void button1_Click(object sender, EventArgs e){t = new Thread(new ThreadStart(ThMethord));t.Start();}public void ThMethord(){MessageBox.Show("线程启动");}private void Form1_FormClosed(object sender, FormClosedEventArgs e){if (t.IsAlive){t.Abort();//关闭线程}}}}完整程序代码如下:★ ★★★★Form1.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;using System.Threading;using System.Diagnostics;using System.Net.Mail;using System.IO;namespace ThreadTest{public partial class Form1 : Form{private Thread t = null;public Form1(){InitializeComponent();}private void button1_Click(object sender, EventArgs e){t = new Thread(new ThreadStart(ThMethord));t.Start();}public void ThMethord(){MessageBox.Show("线程启动!");}private void Form1_FormClosed(object sender, FormClosedEventArgs e){if (t.IsAlive){t.Abort();}}}}★ ★★★★Form1.Designer.cs窗体设计文件完整程序代码★★★★★namespace ThreadTest{partial class Form1{/// /// 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.button1 = new System.Windows.Forms.Button();this.SuspendLayout();//// button1//this.button1.Location = new System.Drawing.Point(122, 191);this.button1.Name = "button1";this.button1.Size = new System.Drawing.Size(75, 23);this.button1.TabIndex = 0;this.button1.Text = "启动线程";this.button1.UseVisualStyleBackColor = true;this.button1.Click += new System.EventHandler(this.button1_Click);//// Form1//this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;this.ClientSize = new System.Drawing.Size(345, 287);this.Controls.Add(this.button1);this.Name = "Form1";this.Text = "Form1";
