Answer 1

using System.Threading;Thread t1 = new Thread(new ThreadStart(t1));
t1.start();Thread t2 = new Thread(new ThreadStart(t2));
t2.start();

Answer 2

public void t1()
{
this.Invoke((EventHandler)delegate{this.label32.ForeColor = Color.Blue;});
}public void t2()
{
this.Invoke((EventHandler)delegate{this.comboBox1.Items.Clear();});
goods.Class1 goods_cl1 = new goods.Class1();
string stt = this.comboBox1.Text.Trim().ToString();
int all = goods_cl1.Get_all_Goods_Names().Tables[0].Rows.Count - 1;
//如果是vs2008
List<string> items = new List<string>();
for (int i = all, j = 0; j <= i; j++)
{
items.Add(goods_cl1.Get_all_Goods_Names().Tables[0].Rows[j][0].ToString().Trim());
}
this.Invoke((EventHandler)delegate
{
this.comboBox1.Items.AddRange(items);
this.label32.ForeColor = Color.Red;
});
}private void button1_Click(object sender, EventArgs e)
{
new Thread((ThreadStart)delegate{t1();}).Start();
new Thread((ThreadStart)delegate{t2();}).Start();
}
大量界面更新，多线程意义不大，要频繁的同步ui线程。
