WinForm解决多线程操作控件问题 线程间操作无效: 从不是创建控件的线程访问它"

using System.Windows.Forms;
using System.Threading;
namespace TestWinForm
{
    public partial class Form1 : Form
    {

        
        public Form1()
        {
            InitializeComponent();   
        }

        delegate void setTextDlg(string v);
        delegate void setButton1Status(string v);
        private void doSomething()
        {

            setButton1Status bt1 = new setButton1Status(setButton);
            button1.BeginInvoke(bt1, new object[] { "false" });

                for (int i = 0; i < 100; i++)
                {
                    setTextDlg st = new setTextDlg(setTxt);
                    //this.Invoke(st, new object[] {i.ToString() });   // 方法1
                    label1.BeginInvoke(st, new object[] { i.ToString() }); //方法2
                    Thread.Sleep(30);
                }
                setButton1Status bt = new setButton1Status(setButton);
                button1.BeginInvoke(bt, new object[] { "true" });
                //MessageBox.Show("ok");             
        }

        void setTxt(string v)
        {
            label1.Text = v;           
        }

        void setButton(string v)
        {
            button1.Enabled = (v == "true" ? true : false);
        }

        private void button1_Click(object sender, EventArgs e)
        {
            //button1.Enabled = false;
            Thread th1 = new Thread(doSomething);
            th1.Name = "th1";
            th1.IsBackground = true;
            th1.Start();
        }
    }
}
