windowsform中的控件调用--2

昨天百度到这篇文章感觉很不错（给一个我的博客的连接吧~~~http://blog.youkuaiyun.com/deandingding/article/details/39742985）今天自己在这儿玩着玩着，又玩出了一个关于这个问题的新方法，而且写起来也很简单。。。。也许很多弊端，但是目前我还不知道，如果有大牛能看出来，感激不敬！！

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public delegate void Test();
       
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            //Thread tr = new Thread(CrossThread);
            Thread tr = new Thread(new ThreadStart(CrossThread));
            tr.IsBackground = true;
            tr.Start();

namespace WindowsFormsApplication1
{
    class Class1
    {
        Form1 f1;

        {
            this.f1 = f1;
        }
        public Class1()
        {
        }
        public void Function()
        {
            f1.textBox1.Text = DateTime.Now.ToString();//这个TextBox1这个东西记得在<span style="font-family: Arial, Helvetica, sans-serif;">InitializeComponent（）这个里面把它改成public</span>

        }
    }
}
