怎么把多线程中的参数传出啊？

namespace test
{
public partial class Form1 : Form

public Form1()

}
private static string str_url = string.Empty;
public delegate void SetTextHandler(string text);
private void toolStripButton1_Click(object sender, EventArgs e)
{
if (toolStripTextBox1.Text.Length > 0)
{
str_url = toolStripTextBox1.Text.Trim();
ParameterizedThreadStart ParStart = new ParameterizedThreadStart(GetPageSource);
Thread myThread = new Thread(ParStart);
//是否背景线程根据自己需要加，加上后理论上不影响界面的操作，就是不卡
myThread.IsBackground = true;
object o = str_url;
myThread.Start(o);
//GetPageSource(toolStripTextBox1.Text.ToString().Trim());
}
}
private void GetPageSource(object url)
{
Uri uri = new Uri(url.ToString());
HttpWebRequest hwReq = (HttpWebRequest)WebRequest.Create(uri);
HttpWebResponse hwRes = (HttpWebResponse)hwReq.GetResponse();
hwReq.Method = "Get";
hwReq.KeepAlive = false;
//从输入的网站提取HTML源码
StreamReader reader = new StreamReader(hwRes.GetResponseStream(), System.Text.Encoding.GetEncoding("GB2312"));
settext(reader.ReadToEnd());
}
private void settext(string text)
{
if (richTextBox1.InvokeRequired == true)
{
SetTextHandler set = new SetTextHandler(settext);
richTextBox1.Invoke(set, new object[] { text });
}
else
{
richTextBox1.Text = text;
}
}
}
}
在上面代码上
private void settext(string text)里的richtextbox1.text在其它函数里调用会出错，我想要把text这个内容在其它函数内调用，应该怎么办啊？ --------------------编程问答-------------------- 你写个委托 处理到 richTextBox1.Text = text;这的时候 触发这个委托 然后把值传给这个委托 让这个委托去赋值 --------------------编程问答-------------------- 新手啊，不懂怎么委托，能写个实例么，谢谢了 --------------------编程问答-------------------- 不懂委托，那就加一行代码
public Form1()
{
InitializeComponent();
Control.CheckForIllegalCrossThreadCalls = false;
}
--------------------编程问答--------------------
LS的 Control.CheckForIllegalCrossThreadCalls = false; 是跨线程取值
补充：.NET技术 , C#
