是否可以从其他表单触发点击事件？ [英] Is it possible to trigger a click event from another form?

问题描述

我需要运行另一个表单上的按钮的代码。可以用其他形式来做吗？如果您说可以将其宣布为公开，则可以：

I need to run the code of a button that is on another form. is it possible to do it from a different form? if you say that it is possible by declaring it public then:

1. 我如何宣布控制权公开？


2. 如何将正确的事件传递给 button_click ？它需要两个参数-我该如何传递它们呢？

1. how do i declare a control public?
2. how do i pass the correct events into button_click? it takes two parameters - how do i pass them,?

推荐答案

可以在表单 公共中进行控制，但不建议这样做，您可以执行以下操作：

It's possible to make a control in a Form public, but not recommended, you can do the following:

1）以第一种形式声明一个新事件（form1）ButtonFirstFormClicked

1) Declare a new event in the first form (form1) ButtonFirstFormClicked

public event EventHandler ButtonFirstFormClicked;

并在Button.Click事件处理程序中触发此事件

and trigger this event in the Button.Click event handler

void button_Clicked(object sender, EventArgs e)
{

    // if you're working with c# 6.0 or greater
    ButtonFirstFormClicked?.Invoke(sender, e);

    // if you're not then comment the above method and uncomment the below
    //if (ButtonFirstFormClicked!= null)
    //     ButtonFirstFormClicked(sender, e);
}  

2）在第二种形式（form2）中订阅事件

2) In the second form (form2) subscribe the event

form1.ButtonFirstFormClicked += (s, e)
{
 // put your code here...
}
