最近在編寫C/S結構應用程序時，感覺窗體的標題欄樣式太死板了，標題文字不能更改大小、顏色、字體等，按鈕不能隱藏等問題，在網上也查找了許多相關的資料，沒有找到合適的解決方案，發現許多人也在尋求這個問題，最后我決定自己研究動手畫一個標題欄出來，經過今天一天的研究與編寫，終于完成全部功能，現公布一下我的設計思路。

一、去掉Form類自帶的標題欄 ? ? ? ? ? ? ? ? ? ? ? ??

? ? ? 要去掉自帶的標題欄有兩種方法，第一方法是直接將FormBorderStyle設為 System.Windows.Forms.FormBorderStyle.None，但設置過后，窗體無法改變大小，考慮到后期這些功能還是需要的，所以我采用了第二種方法，第二種方法是可以忽略FormBorderStyle，只需要將ControlBox設為 false，并將Text設為空即可，這種方法隱藏標題欄，若FormBorderStyle不是固定模式，則可以通過拉伸窗體邊框改變大小的。

二、創建自定義窗體類 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ??

首先創建一個窗體，如下圖：

然后去掉Text默認的文字，并將ControlBox設為 false，此時標題欄將自動隱藏掉了，如下圖：

去掉標題欄后，就需要重畫新的標題欄，畫標題欄很簡單，方法也很多，我這里是采用一個Panel，將Dock設為Top，讓其項部固定，并設高度為30像素，再在其中添加三個按鈕，依次為：button1（關閉）,button2（最大化）,button3（最小化）,三個按鈕的設為Size相同，且將Anchor都設為Top Right Bottom，這樣就實現了讓三個按鈕在右邊固定位置，如下圖：

界面部份已經完工，剩下的就是編寫代碼了，由于代碼較多，我先將代碼貼出來，稍后再講解。

代碼中FormBorderStyle覆蓋父類的同名屬性，主要是實現根據不同的窗體，能夠自動調整標題欄按鈕，因為當FormBorderStyle為FormBorderStyle.Sizable或FormBorderStyle.SizableToolWindow時，才需要最大化按鈕，否則都是不需要的。不需要的情況下，將移除最大化按鈕對象button2,

titlepanel.Controls.Remove(button2);

由于隱藏自帶的標題欄需要確保Text屬性為空,ControlBox為False，所以我這里采取了重寫這兩個屬性，并加上Browsable(false)，讓其在編輯器中不可見。

Title，TitleFont，TitleColor,TitleBarBackColor為新增自定義屬性，分別用于設置標題文字，標題文字樣式，標題文字顏色，標題欄背景色。

重寫MaximizeBox與MinimizeBox兩個屬性，使其根據設為True與False時，能相應的調整標題欄按鈕。

私有方法：ResetTitlePanel，用于重設標題欄按鈕屬性。

方法Titlebutton_Click這個簡單，主要用于實現標題欄上三個按鈕點擊時所要執行的操作。

Titlepanel_MouseDown，Titlepanel_MouseUp ，Titlepanel_MouseMove 三個方法是用于實現點擊鼠標右鍵并按住移動就能夠移動窗體，Titlepanel_DoubleClick方法是實現雙擊時能夠最大化或還原窗體功能。

最后的titlepanel_ControlRemoved與titlepanel_ControlAdded，實現的功能是當增加或移除按鈕時，調整按鈕的位置。

三、使用自定義窗體類 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ??

使用就比較簡單了，先是新增一個窗體，然后將窗體類的父類由Form改為自定義窗體類（ZForm）即可，然后再切換到設計視圖頁面，是不是發現界面已經變化了呢，這時候就可以依據的想法靈活設置窗體標題欄樣式，如下圖：

public partial class Form1 : ZControls.ZForm{public Form1(){InitializeComponent();}}

將MaximizeBox設為False時，運行的效果，是不是有點爽啊！

好了，都說完了，其實也很簡單，我相信大部份高手都是不屑一看的，但此處只是作為一個學習與參考，可能大家有更好的方法，歡迎大家交流，共同進步。
