WinForm调用主窗体Close方法失败：从不是创建控件的线程访问它

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        (new Form2()).Show(this);
    }
}

public partial class Form2 : Form
{
    public Form2()
    {
        InitializeComponent();
    }

    private void Form2_FormClosed(object sender, FormClosedEventArgs e)
    {
        Form1 frm = this.Owner as Form1;
        if (frm != null)
        {
            frm.Close();
        }
    }
}

private void Form2_FormClosed(object sender, FormClosedEventArgs e)
{
    Application.Exit();
}
