关闭Windows窗体可用于一种窗体，但不能应用于另一窗体

Question

I have crated a windows form application.

VS2012 created a form1 form to me

then I crated a second form called Main

there is a button on form1 form to go to Main form

when I run the application using vs2012, and then I click the x button at the top right of form form1 , the form close and I can start working on vs. but the problem is when I click the x button at the top right of the form Main , I can't start working on VS, but I need to click Stop Debugging red button in the vs in order to be able to type in vs.

so my question is when I give this application to my customers, and when the click the x button at the top right of the form, I need the application to close totally, I don't need them to go the task manager and close the application from it.

Answer 1

Your application starts with Form 1 , when you close it you are closing the application. Main is just a form, when you close it you are closing the form. What you need to is, go to FormClosing event of Main form and add

Application.Exit();

Answer 2

进入FormClosing事件并输入以下代码：

System.Envirenement.Exit(0);

Answer 3

What do you do with form1 when you go to Main ? If you just hide it in order to show the other, then close the other one, while just keeping form1 hidden, then form1 will naturally still be running, even if Main is closed.

Sounds like the logical thing to do would be to go back to form1 from Main when you close the latter - otherwise, you can close both using Application.Exit(0) on the appropriate event.

In either case, it would be easier to answer this if you had provided some actual code.

Update:

You could also use System.Environment.Exit(0) , but that might require more privileges, which might or might not affect your situation. Again - some code would be helpful.

In regard to your comments, see this answer for more info about termination options.

Answer 4

Problem is because your Form1 form still running(hidden).
If you use Form1 only for open your Main form. Then delete Form1 and set Main as StartUp form in Properties of your proejct:
Application -> StartUp form

After this when you close Main form application will be closed properly

If you use Form1 then you need close Form1 too after you close Main form.
Use FormClosed eventhandler for this purpose

Answer 5

Right click on Main form -> Properties
on the Event tab choose FormClosing event
and write this code

private void Main_FormClosing(object sender, FormClosingEventArgs e)
        {
           System.Environment.Exit(0);
        }
