这是一个简单的例子,希望对你有帮助!首先在窗体上,创建一个listbox,lable.
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;namespace AccessControl
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
} private void Form1_Load(object sender, EventArgs e)
{
Thread newthread = new Thread(new ThreadStart(BackgroundProcess));
newthread.Start(); } /// <summary>
/// 定义一个代理
/// </summary>
private delegate void CrossThreadOperationControl(); private void BackgroundProcess()
{
// 将代理实例化为一个匿名代理
CrossThreadOperationControl CrossDelete = delegate()
{
int i = 1;
while (i<5)
{
// 向列表框增加一个项目
listBox1.Items.Add("Item " + i.ToString());
i++;
}
label1.Text = "我在新线程里访问这个lable!";
listBox1.Items.Add(label1.Text);
} ;
listBox1.Invoke(CrossDelete);
} }
}
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;namespace AccessControl
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
} private void Form1_Load(object sender, EventArgs e)
{
Thread newthread = new Thread(new ThreadStart(BackgroundProcess));
newthread.Start(); } /// <summary>
/// 定义一个代理
/// </summary>
private delegate void CrossThreadOperationControl(); private void BackgroundProcess()
{
// 将代理实例化为一个匿名代理
CrossThreadOperationControl CrossDelete = delegate()
{
int i = 1;
while (i<5)
{
// 向列表框增加一个项目
listBox1.Items.Add("Item " + i.ToString());
i++;
}
label1.Text = "我在新线程里访问这个lable!";
listBox1.Items.Add(label1.Text);
} ;
listBox1.Invoke(CrossDelete);
} }
}
{ Form2 ft = new Form2();
ft.button1.text = "11"; }
Form1中的案件事件我写这这样,点击没效果。。
