如何防止当前表单之外的点击？

Question

我想要当用户单击按钮时将打开的表单，我不希望用户单击此表单之外的其他任何位置（防止他单击父表单上的任何其他按钮），我想限制其在此表单内的操作表单，直到他关闭该表单（确保此表单是最顶部），并且我希望该表单对表单外部的任何点击发出警报（闪烁），以便用户理解他必须首先关闭它。

Answer 1

When opening the form instead of

Form form = new Form();
form.Show();

use

Form form = new Form();
form.ShowDialog()

Answer 2

Super easy fix! I assume your code to show the form right now is

form.Show();

To create/show an instance of the form that is modal (restricts clicking to that form) all you need to change is that line to:

form.ShowDialog();
