Post you requirement. Goto is not a good practice.

First off, don't use Goto - in fact forget it exists for a couple of years, by which time you should have a better idea of when it is appropriate to use it.
Instead, try something like this:

C#

private void button1_Click(object sender, EventArgs e)
    {
    if (MessageBox.Show("Enter more data?", "Data Saved", MessageBoxButtons.YesNo) == DialogResult.No)
        {
        Close();
        }
    }

Which closes your form if the user doesn't want to enter more data.

that is correct, but when dialogresult=Yes i want to user can add some information in textboxes and he can again click the button and this cycle can continue.

That's the whole idea: until the form is closed, your use can continue to add info. When he says "No, I'd finished" the form closes and he can't enter data any more.

This isn't like console programming: events happen at "random" intervals and your code responds to them - you don't force the user to do anything in any particular order.

So the user enters his data, presses the "Save" button and you save it and ask if he wants to enter more. You don't try to use "goto" to jump outside an event handler! :laugh:

i can write code for the time that user says "i do not want to enter any information" but i do not know what to do when he says "i want to enter more information".
if i use goto statement what i must do? because i do not have more time to edit my program structure.

Do not use goto.

If you are using buttons, and forms, then you react to events, you do not control what happens where.
I can't tell you what to do in detail, without seeing your code - but by the sound of it you are trying to write a console application in windows forms: and that won't work without radical changes!
