A situation happened

this.FormClosing += btn_close_Click; void btn_close_Click(object sender, EventArgs e) { if (MessageBox.Show(this, "realy exit?", "closing program", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes) { this.Close(); } }

After the modal window, the program still turns off.

Tell me how to fix it.

It should be something like this:

 void btn_close_Click(object sender, FormClosingEventArgs e) { if (MessageBox.Show(this, "realy exit?", "closing program", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes) { this.Close(); } else { e.Cancel = true; } }

CancelEventArgs.Cancel property - returns or sets a value indicating whether the event should be canceled.

    this.Close is optional, since we are this.FormClosing += ... closing ( this.FormClosing += ... ). Here a single-line solution is e.Cancel = MessageBox.Show(...) != DialogResult.Yes; : e.Cancel = MessageBox.Show(...) != DialogResult.Yes; . - Uranus
