本文实例讲述了C#停止线程的方法。分享给大家供大家参考。具体实现方法如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WinFormApp
{
public partial class Form1 : Form
{
System.Threading.CancellationTokenSource cancel = new System.Threading.CancellationTokenSource();
System.Threading.Thread[] thread;
int len = 2;
public Form1()
{
InitializeComponent();
thread = new System.Threading.Thread[len];
}
void RunThread()
{
ThreadInvoke.SetEventInvokeValue(richTextBox1, "即将开始运行线程." );
System.Threading.Thread t = null ;
for ( int i = 0; i < len; i++)
{
t = new System.Threading.Thread( new System.Threading.ThreadStart(Sample));
t.Name = "thread_0" + i.ToString();
t.IsBackground = true ;
thread.SetValue(t, i);
t.Start();
}
}
void Sample()
{
string name = System.Threading.Thread.CurrentThread.Name;
ThreadInvoke.SetEventInvokeValue(richTextBox1, "正在运行线程：" + name);
while ( true )
{
if (cancel.IsCancellationRequested)
{
ThreadInvoke.SetEventInvokeValue(richTextBox1, "线程：" + name + " 停止运行..." );
//线程被终止后回调
cancel.Token.Register( delegate
{
ThreadInvoke.SetEventInvokeValue(richTextBox1, "线程：" + name + " 停止运行之后的回调函数..." );
});
break ;
}
}
}
void ShowStatu()
{
StringBuilder sb = new StringBuilder();
for ( int i = 0; i < len; i++)
{
if (thread[i].IsAlive == true )
{
sb.AppendLine( "线程：" + thread[i].Name.ToString() + " 还在运行..." );
}
}
if (sb.ToString() == "" )
{
sb.AppendLine( "线程已经全部停止..." );
}
richTextBox1.Text += sb.ToString();
}
/// <summary>
/// 开始运行线程
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button1_Click( object sender, EventArgs e)
{
RunThread();
}
/// <summary>
/// 显示所有的线程状态
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button2_Click( object sender, EventArgs e)
{
ShowStatu();
}
/// <summary>
/// 终止所有的线程
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void button3_Click( object sender, EventArgs e)
{
cancel.Cancel();
}
}
}
希望本文所述对大家的C#程序设计有所帮助。
