在winforms的MessageBox中居中確定按鈕

我正在學習C＃，作爲它的一部分，我編寫了一個小型應用程序，它包含兩組按鈕，每組按鈕各有兩個按鈕。還添加了關閉應用程序的按鈕。一切正常。還有MessageBox，顯示應用程序將被關閉。 這裏是一個小問題，我錯誤：該消息框內的確定按鈕不是水平居中。我想有一種方法來對齊該按鈕，但是讓我感到困惑的是爲什麼它不是默認居中？作爲解說這裏是截圖：在winforms的MessageBox中居中確定按鈕

Form with radio buttons

MessageBox with OK button

這裏是代碼，以及：

using System; 
using System.Drawing; 
using System.Windows.Forms; 

public class myForm : Form

'MessageBox'類在內部調用一些您無法控制的Windows API。我認爲沒有辦法改變這一點。 – 2013-05-02 15:17:27

我想，如果你要在Windows XP中運行你的程序，它將被集中。我認爲（可能是錯誤的），但如果你要改變.Net框架，你的應用程序的目標是舊版本，它將集中。它基本上管理什麼微軟喜歡的外觀 – Sayse 2013-05-02 15:19:05
