如何告诉另一个表格关闭的表格[复制](How to tell a form that another form Closes [duplicate])

如何告诉另一个表格关闭的表格[复制](How to tell a form that another form Closes [duplicate])

这个问题在这里已经有了答案：

Winform表单关闭事件 1的答案

我有称为“GameForm”的“form1”。 它发送的东西是这样的：

var tmp = new Pjeu(P1, P2); tmp.Show();

两个“P”都是一类。 在“GameForm”中，它最终找到了胜利者并且像这样关闭自己：

MessageBox.Show("Victory " + label3.Text, "Game Finished", MessageBoxButtons.OK); this.Close();

我怎样才能让“Form1”知道它已关闭？ 我需要两次进行比赛才能找到2个赢家，所以我需要我的第一个表格来做两次游戏，然后等待它关闭以创建另一个。 我找到了一些答案，但没有在我的情况下工作。

This question already has an answer here:

Winform form closed event 1 answer

I have "form1" that calls "GameForm". It sends stuff to is like such:

var tmp = new Pjeu(P1, P2); tmp.Show();

Both "P" are a class. In the "GameForm", it eventually finds a winner and closes itself like such:

MessageBox.Show("Victory " + label3.Text, "Game Finished", MessageBoxButtons.OK); this.Close();

How can i make the "Form1" know that it has closed? I need to do the Game twice to find 2 winner so i need my first form to do the game twice and wait for it to be closed to make another one. I found some answers but none that worked in my context.

在你的GameForm中，你可以创建一个自定义事件，并在表单关闭之前提升它。 并且在Form1中只需订阅此事件。

在GameForm中：

public delegate void Winner(); public event Winner OnWinnerFound; ... OnWinnerFound(); // Just call your event MessageBox.Show("Victory " + label3.Text, "Game Finished", MessageBoxButtons.OK); this.Close();

在你的Form1中：

var tmp = new Pjeu(P1, P2); tmp.OnWinnerFound+=WinnerFound; tmp.Show(); ... private void WinnerFound() { //Your code here }

我不记得，也许有一个内置的事件，当表单关闭或表单关闭时发生。

in your GameForm you can create a custom event and rise it before form is closed. And in your Form1 just subscribe for this event.

In GameForm:

public delegate void Winner(); public event Winner OnWinnerFound; ... OnWinnerFound(); // Just call your event MessageBox.Show("Victory " + label3.Text, "Game Finished", MessageBoxButtons.OK); this.Close();

In your Form1:

var tmp = new Pjeu(P1, P2); tmp.OnWinnerFound+=WinnerFound; tmp.Show(); ... private void WinnerFound() { //Your code here }

I don't remember, maybe there is a built in event, which occurs when form is closed or form is closing.
