C# Winform 跨线程调用窗体-526互联

还是用委托的方式。

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

    private Form2 form2;

    private void ShowForm2()
    {
        Action action = Show_;
        Invoke(action);
    }
    private void Show_()
    {
        form2 = new Form2();
        form2.Show();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        /****非跨线程****/
        //showForm2();

        /****跨线程*****/
        Thread thread = new Thread(ShowForm2);
        thread.IsBackground = true;
        thread.Start();
    }
}
