Solution 2

To answer your question:

C#

Form1 f = new Form1();
f.Closed += new ....
f.ShowDialog();

and in the Closed event handler for Form1

C#

Form2 f = new Form2();
f.ShowDialog();

Maybe if you described EXACTLY what you're trying to do, we could give you a better answer.

Solution 3

on button click of form1 code this to close the current window:

this.Close();

and write this to open the new window:

Form2 f2 = new Form2();
f2.ShowDialog();

hope this helps :)

5 for answering the direct question asked, however for what I suspect the OP wants, closing the first form will close the application.

yes you are right it will close the application, even I don't understand what OP wants, just gave the answer to his specific requirement.
thanks for 5 :)

After your response to Ace_Hardlight, I think this tip/trick will help you:

Solution 1

Try:

//form to open

Form1 f = new Form1();
f.show();

//current form you want to close

this.close();

when i am run application form1 is open when i am click on button on from1 then form2 is open and form1 is close??

using this.close(); all form is close

Ace_Hardlight 7-Jul-11 1:25am

that's cause form1 is then the parent form. When you close the parent form all child forms are closed aswell. However, if you use this.Close() on form2, it will only close form2 and form1 will still be open. Which form do you want to close and which one do you want open?
