Question

我正在为我的软件编写API，它有很多接口，我的软件只是继承了它们我希望API用户有可能在X毫秒后做一些事情，如下所示：

public void PerformAction(Action action, int delay)
{
   Task.Run(async delegate
   {
       await Task.Delay(delai);
       Form.BeginInvoke(action);
       // I invoke on the Form because I think its better that the action executes in my main thread, which is the same as my form's thread
   });
}

现在我知道Task就像一个新线程，我只是想知道，这对我的软件有害吗？还有其他更好的方法吗？
该方法将被执行很多，所以我不知道这种方法是好还是坏

Answer 1

您不应该为此创建新任务，而是可以将方法设为任务，如下所示：

public async Task PerformAction(Action action, int delay)
{
   await Task.Delay(delay);
   action(); //this way you don't have to invoke the UI thread since you are already on it
}

然后简单地使用它：

public async void Butto1_Click(object sender, EventArgs e)
{
    await PerformAction(() => MessageBox.Show("Hello world"), 500);
}

Answer 2

    public async Task PerformAction(Action action, int delay)
    {
        await Task.Delay(delay);
        action();
    }

延迟API动作
