菜鸟解决 必须将当前线程设置为单线程单元(STA)模式的报错

  private static string[] picAdd = new string[10];

private void button21_Click_1(object sender, EventArgs e)
        {

            InvokeThread.Start();
            InvokeThread.Join();
        }
        private void InvokeMethod()
        {
            //定义控件数组
            PictureBox[] mypic = { pictureBox1, pictureBox2, pictureBox3, pictureBox4, pictureBox5, pictureBox6, pictureBox7, pictureBox8, pictureBox9, pictureBox10 };

            if (pictureBox10.Image == null)

                for (n = 0; n < 10; n++)
