Closing a single form in c#.net

Question

I have two forms ie form1 and form2. Now I have a button on form1. On click of a button i want to close form1 and show form2. The code I have written is like this:

form2 f2=new form2()
f2.show();
this.close()

But this.close closes the entire application.

Could someone please help me?
Thanks in advance.

Do not ever again lock a question for editing. It is extremely rude. (to E.F. Nijboer)

When improving the question it gets locked but you still would be able to answer it though. It isn't rude, it's simply to prevent collisions.

If you look in Program.cs, you'll see that Form1 is passed in to Application.Run.

When you close Form1, the framework assumes you're exiting the program.

You can hide Form1, then show Form2, or you can create a background manager and use that in Application.Run to control which form is being used. This will feel a bit hackish unless you find/work out a decent pattern for knowing which forms are open and when you're supposed to close. You will need to create and manage an ApplicationContext that shuts itself down when you have no more forms open. It should also be responsible for creating the forms.

Cheers.

Solution 1

This is because you defined Form1 as your main form. You could hide it instead (form1.visible = false;) of closing it.

It is possible to close form1 but you have to run the second form to get the messageloop going again, like this:

C#

Application.Run(new form2());

Good luck!

Solution 3

As form1 is parent and form2 is child form.. so it is not possible to open a child form when a parent form is closed.

It was only to post SPAM, so I guess they don't care too much :-)
