                Thread T1 = new Thread(new ParameterizedThreadStart(Form1_KeyPress));
                T1.Start(sender,e);
                for (int i = 0; i < 300;i++ )
                {
                    Thread.Sleep(100);
                    pictureBox2.Left++;

推荐答案

我似乎找不到任何会启动的方法接受2个参数。你可以看一下 Threading.Thread [ ^ ]类并查找任何可以接受2个参数的方法。



答案，它不能通过，您可以将sender（Object）或e（Event）传递给方法。 Start只接受一个argumnt传递。

I don't seem to find any Start method that would accept 2 parameters. You can have a look at the Threading.Thread[^] class and look for any method that would accept 2 parameters.

Answer, it can't be passed, you can either pass the sender (Object) or the e (Event) to the method. The Start accepts only one argumnt to be passed down.

你没有。

EventArgs是作为Start方法处理的一部分为你创建的，发送到事件处理程序。您需要创建EventArgs实例的唯一时间是创建自己的事件并发送信号，以便处理程序可以正确使用它们。

You don't.
The EventArgs are created for you as part of the Start method processing, and sent to the event handler. The only time you need to create an instance of EventArgs is when you are creating your own events and signalling them so that handlers can work with them correctly.
