接上节多线程学习:http://blog.csdn.net/iuhxq/archive/2005/10/12/500295.aspx
本节把Form主线程从其他线程分离出来,实现数据从线程的传入传出
代码如下:
From1.cs代码如下: using System; using System.Drawing; using System.Collections; using System.ComponentModel; using System.Windows.Forms; using System.Data; using System.Threading; namespace student { /// <summary> /// http://blog.csdn.net/iuhxq /// </summary> public class Form1 : System.Windows.Forms.Form { private System.Windows.Forms.Button button1; private System.Windows.Forms.Button button2; private System.Windows.Forms.Button button3; private Class1 c; private System.Windows.Forms.ListView listView1; private System.Windows.Forms.ColumnHeader columnHeader1; private System.Windows.Forms.ColumnHeader columnHeader2; /// <summary> /// 必需的设计器变量。 /// </summary> private System.ComponentModel.Container components = null; public Form1() { // // Windows 窗体设计器支持所必需的 // InitializeComponent(); // // TODO: 在 InitializeComponent 调用后添加任何构造函数代码 // } /// <summary> /// 清理所有正在使用的资源。 /// </summary> protected override void Dispose( bool disposing ) { if( disposing ) { if (components != null) { components.Dispose(); } } base.Dispose( disposing ); } #region Windows 窗体设计器生成的代码 /// <summary> /// 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。 /// </summary> private void InitializeComponent() { // // Class1初始化 // this.c = new Class1(); this.c.Update += new student.Class1.EventHandler(c_Update); this.button1 = new System.Windows.Forms.Button(); this.button2 = new System.Windows.Forms.Button(); this.button3 = new System.Windows.Forms.Button(); this.listView1 = new System.Windows.Forms.ListView(); this.columnHeader1 = new System.Windows.Forms.ColumnHeader(); this.columnHeader2 = new System.Windows.Forms.ColumnHeader(); this.SuspendLayout(); // // button1 // this.button1.Location = new System.Drawing.Point(24, 216); this.button1.Name = "button1"; this.button1.TabIndex = 1; this.button1.Text = "Add"; this.button1.Click += new System.EventHandler(this.button1_Click); // // button2 // this.button2.Location = new System.Drawing.Point(104, 216); this.button2.Name = "button2"; this.button2.TabIndex = 2; this.button2.Text = "Del"; this.button2.Click += new System.EventHandler(this.button2_Click); // // button3 // this.button3.Location = new System.Drawing.Point(184, 216); this.button3.Name = "button3"; this.button3.TabIndex = 3; this.button3.Text = "DelAll"; // // listView1 // this.listView1.Columns.AddRange(new System.Windows.Forms.ColumnHeader[] { this.columnHeader1, this.columnHeader2}); this.listView1.FullRowSelect = true; this.listView1.GridLines = true; this.listView1.Location = new System.Drawing.Point(0, 0); this.listView1.Name = "listView1"; this.listView1.Size = new System.Drawing.Size(288, 208); this.listView1.TabIndex = 5; this.listView1.View = System.Windows.Forms.View.Details; // // columnHeader1 // this.columnHeader1.Text = "线程编号"; this.columnHeader1.Width = 81; // // columnHeader2 // this.columnHeader2.Text = "value"; this.columnHeader2.Width = 180; // // Form1 // this.AutoScaleBaseSize = new System.Drawing.Size(6, 14); this.ClientSize = new System.Drawing.Size(292, 266); this.Controls.Add(this.listView1); this.Controls.Add(this.button3); this.Controls.Add(this.button2); this.Controls.Add(this.button1); this.Name = "Form1"; this.Text = "Form1"; this.Load += new System.EventHandler(this.Form1_Load); this.ResumeLayout(false); } #endregion /// <summary> /// 应用程序的主入口点。 /// </summary> [STAThread] static void Main() { Application.Run(new Form1()); } private void Form1_Load(object sender, System.EventArgs e) { } private void c_Update(int index) { listView1.Items[index].SubItems[1].Text = c.Result[index].ToString(); } private void button1_Click(object sender, System.EventArgs e) { listView1.Items.Add(new ListViewItem(new string[]{c.Result.Count.ToString(),"0"})); c.Add(); } private void button2_Click(object sender, System.EventArgs e) { int index = c.Del(); if(index>=0) { listView1.Items.RemoveAt(index); } } } } 添加类Class1: Class1代码如下: using System; using System.Collections; using System.Threading; namespace student { /// <summary> /// Class1 的摘要说明。 /// </summary> public class Class1 { public ArrayList Threads = new ArrayList(); public ArrayList Result = new ArrayList(); public event EventHandler Update; public delegate void EventHandler(int index); public Class1() { // // TODO: http://blog.csdn.net/iuhxq // Update += new EventHandler(Class1_Update); } private void Process() { int i = 1; while(true) { i++; int index = Threads.IndexOf(Thread.CurrentThread); Result[index] = i; if(Update!=null)Update(index); Thread.Sleep(0); } } public int Add() { Thread t = new Thread(new ThreadStart(Process)); t.Start(); Threads.Add(t); lock(Result) { Result.Add(0); } return Threads.Count-1; } public int Del() { int count = Threads.Count; if(count>0) { Thread t1 = (Thread)Threads[count-1]; if(t1.IsAlive) { t1.Abort(); } Threads.RemoveAt(count-1); lock(Result) { Result.RemoveAt(count-1); } } return count-1; } private void Class1_Update(int index) { } } }
