晚上写的刚好也适合楼主的问题；
http://blog.csdn.net/zhzuo/archive/2004/07/08/37262.aspx
主要就是调用
Control.Invoke 方法
或异步调用
Control.BeginInvoke 方法
需要定义方法的委托
public delegate void PingCompletedHandler(object sender,PingEventArgs e);
//更新信息显示，Invoke异步调用
private void pingCommand_PingCompleted(object sender,PingEventArgs e)
{
this.listView1.BeginInvoke(new UpdateListViewHandler(MessageInfoShow),new object[]{e.PingResult});
}
//更新ListView
private void MessageInfoShow(string[,] pingResult)
{
this.listView1.Items.Insert(0,new ListViewItem(new string []{pingResult[0,0],pingResult[0,1]}));
if(this.listView1.Items.Count ==this.hostCount)
{
this.listView1.Refresh();
TimeSpan ts = (TimeSpan)(DateTime.Now-this.startTime);
this.labelTime.Text = "检测时间:"+ts.TotalSeconds.ToString()+"秒";
this.buttonPing.Enabled = true;
}
}

public class Form1 : System.Windows.Forms.Form
{
private delegate void UpdateDelegate(string str);
private void button1_Click(object sender, System.EventArgs e)
{
Thread t = new Thread(new ThreadStart(DoTask));
t.Name = "测试";
t.Start();
}
private void DoTask()
{
string str = Thread.CurrentThread.Name;
UpdateDelegate eh = new UpdateDelegate(UpdateText);
this.textBox1.Invoke(eh,new object[]{str});
}
private void UpdateText(string args)
{
this.textBox1.AppendText(args);
}
}
}
我搜到的一段代码，试试吧
{
private delegate void UpdateDelegate(string str);
private void button1_Click(object sender, System.EventArgs e)
{
Thread t = new Thread(new ThreadStart(DoTask));
t.Name = "测试";
t.Start();
}
private void DoTask()
{
string str = Thread.CurrentThread.Name;
UpdateDelegate eh = new UpdateDelegate(UpdateText);
this.textBox1.Invoke(eh,new object[]{str});
}
private void UpdateText(string args)
{
this.textBox1.AppendText(args);
}
}
