Question

我正在尝试使用线程和任务打开新窗体，但是这段代码打开了新窗口，但是没有显示按钮，文本字段等（表单正在加载）

private void newFomrm_Click(object sender, EventArgs e)
{
    NewForm a = new NewForm(param); // my Form
    Action showMethod = () => {  a.Show(); };
    Task t1 = new Task(showMethod);
    Thread t = new Thread(new ThreadStart(t1.Start));
    t.Start(); 
}

Answer 1

private void button1_Click(object sender, EventArgs e)
    {
        NewForm a = new NewForm(); // my Form
        Action showMethod = () => {
            Invoke(new Action(() => a.Show())); 
        };
        Task t1 = new Task(showMethod);
        Thread t = new Thread(new ThreadStart(t1.Start));
        t.Start(); 
    }

试试这个......你必须把UI操作放在主线程上

线程和任务
