c# - System.Threading.ThreadAbortException（我们如何处理这个异常？）

Question

How can we handle this exception is there some alternative or where i have to make changes?

public Form() { try { Thread t = new Thread(new ThreadStart(StartForm)); t.Start(); 线程.睡眠（3200）；初始化组件（）；t.Abort(); } 捕捉（异常前） { MessageBox.Show（ex.Message）; } } 线程th;

    public void StartForm()
    {
        Application.Run(new Form3());
    }

    private void button1_Click(object sender, EventArgs e)
    {
        this.Close();
        th = new Thread(opennewform);
        th.SetApartmentState(ApartmentState.STA);
        th.Start();
    }
    private void opennewform(object obj)
    {
        Application.Run(new Form2());

    }
