A popular question. The most robust approach to form collaboration is implementing some interface in the form class.
Please see my past answer, other answers and the discussion:
How to copy all the items between listboxes in two forms[^].

—SA

单击按钮或其他东西以打开Form1时，将以下代码放置在该位置.

When you click the button or something to open the Form1, place following code on that location.

Form1 f1 = new Form1();
f1.checkBox1.Checked = !checkBox2.Checked;
f1.Show();

这足以满足您的需求.

当前，每次您选中/取消选中复选框时，都会创建一个新对象，并且我确定您也必须在显示该表单的地方创建一个新对象.


如果表单已经打开，或者您根本不希望打开表单；然后将您的表单Form1 f1 = new Form1();声明放在类的顶部，以获取表单的单个对象.

This is enough to do what you want.

Currently you create a new object everytime you check/uncheck the check box, and I am sure you must be creating a new object where you show the form too.


If form is already open or you don''t want the form to open at all; then put your declaration of form Form1 f1 = new Form1(); at the top of class to get the single object of the form.
