所以这是我的代码.当我单击表单上的X按钮时,消息框显示并单击"无",但是当我单击"是"时,消息框将关闭并快速再次出现,然后第二次单击任一按钮将关闭表单.它出什么问题了？

    Private Sub Config_FormClosing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles MyBase.FormClosing
    Dim result = MessageBox.Show("Would you like to quit?", MessageBoxButtons.YesNo)
    If result = DialogResult.No Then
        e.Cancel = True
    ElseIf result = DialogResult.Yes Then
        Application.Exit()
    End If
End Sub

提前致谢
