2种形式之间的相互作用（隐藏/显示）

Question

I have two WinForm objects, form1 and form2 . What I want to do is:

a. When the user clicks a button on form1 , this will get hidden and a new instance of form2 will show up. So I did:

form1.Hide();
form2 new_session = new form2();
form2.Show(); 

b. From form2 , I would like the user to be able to click a button to recover the originary form1 from which he has generated the form2 instance. Basically, something like:

form2.Hide();
form1.Show();

Clearly, form1 does not exist in the current context. The solution I know to work around this problem is to create a property of form2 where I assign the form1 , so that I can call it back again:

form1 pMyForm;
public form1 myForm
{
get{return pMyForm;}
set{pMyForm = value;}
}

and before to show the form2 ...

form2 new_session = new form2();
form2.myForm = this; 

However, I feel like there's a more proper way of doing this. I thought I could have found the form1 into the property ParentForm of form2 , but I find a null instead. At the same time, I've tried to assign form1 to the property Parent of form2 but I get the error Top-level control cannot be added to a control .

Do you have any suggestion on how to better handle this problem?

Answer 1

Form2.Owner = this;

And

Form1 form = (Form1)this.Owner;
