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)
{
}
}
}
