关于在窗体中使用多线程调用控件的方式

小弟之前在窗体的多线程内调用控件，使用：

System.Windows.Forms.Control.CheckForIllegalCrossThreadCalls = false;

这条语句，网上好像都不建议这么使用，唉，本人用这种方式调试程序也报错，实在没辙，就采用了另外一种网上认为稍微优化点儿的方式，如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Net;
using System.Threading;
namespace WindowsApplication2
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
Thread threadGet1, threadGet2;

threadGet1 = new Thread(new ThreadStart(doGetFromXml1));

threadGet2 = new Thread(new ThreadStart(doGetFromXml2));

threadGet1.Start();
threadGet2.Start();

}

object sysobj = new Object();

public void doGetFromXml1()
{

while (true)
{
lock (sysobj)
{
ShowMessage("oooo\r\n");
}
}

}

public void doGetFromXml2()
{

while (true)
{

lock (sysobj)
{
ShowMessage("aaaa\r\n");
}
}

}

delegate void ShowMess(String s);
void ShowMessage(string s)
{
if (this.richTextBox1.InvokeRequired == true)
{
this.richTextBox1.Invoke(new ShowMess(ShowMessage),new object[]{s});
}
else
{
this.richTextBox1.Text = s;
}
}
}
}

以上是摘自CSDN论坛上的，本人小可耻了一下，以下是本人自己的代码：
