最近在编写C/S结构应用程序时，感觉窗体的标题栏样式太死板了，标题文字不能更改大小、颜色、字体等，按钮不能隐藏等问题，在网上也查找了许多相关的资料，没有找到合适的解决方案，发现许多人也在寻求这个问题，最后我决定自己研究动手画一个标题栏出来，经过今天一天的研究与编写，终于完成全部功能，现公布一下我的设计思路。
一、去掉Form类自带的标题栏
要去掉自带的标题栏有两种方法，第一方法是直接将FormBorderStyle设为 System.Windows.Forms.FormBorderStyle.None，但设置过后，窗体无法改变大小，考虑到后期这些功能还是需要的，所以我采用了第二种方法，第二种方法是可以忽略FormBorderStyle，只需要将ControlBox设为 false，并将Text设为空即可，这种方法隐藏标题栏，若FormBorderStyle不是固定模式，则可以通过拉伸窗体边框改变大小的。
二、创建自定义窗体类
首先创建一个窗体，如下图：
然后去掉Text默认的文字，并将ControlBox设为 false，此时标题栏将自动隐藏掉了，如下图：
去掉标题栏后，就需要重画新的标题栏，画标题栏很简单，方法也很多，我这里是采用一个Panel，将Dock设为Top，让其项部固定，并设高度为30像素，再在其中添加三个按钮，依次为：button1（关闭）,button2（最大化）,button3（最小化）,三个按钮的设为Size相同，且将Anchor都设为Top Right Bottom，这样就实现了让三个按钮在右边固定位置，如下图：
界面部份已经完工，剩下的就是编写代码了，由于代码较多，我先将代码贴出来，稍后再讲解。

private System.Windows.Forms.Button button2;
private System.Windows.Forms.Button button1;
private System.Windows.Forms.Label titlelabel;
}
}
代码中FormBorderStyle覆盖父类的同名属性，主要是实现根据不同的窗体，能够自动调整标题栏按钮，因为当FormBorderStyle为FormBorderStyle.Sizable或FormBorderStyle.SizableToolWindow时，才需要最大化按钮，否则都是不需要的。不需要的情况下，将移除最大化按钮对象button2,
titlepanel.Controls.Remove(button2);
由于隐藏自带的标题栏需要确保Text属性为空,ControlBox为False，所以我这里采取了重写这两个属性，并加上Browsable(false)，让其在编辑器中不可见。
Title，TitleFont，TitleColor,TitleBarBackColor为新增自定义属性，分别用于设置标题文字，标题文字样式，标题文字颜色，标题栏背景色。
重写MaximizeBox与MinimizeBox两个属性，使其根据设为True与False时，能相应的调整标题栏按钮。
私有方法：ResetTitlePanel，用于重设标题栏按钮属性。
方法Titlebutton_Click这个简单，主要用于实现标题栏上三个按钮点击时所要执行的操作。
Titlepanel_MouseDown，Titlepanel_MouseUp ，Titlepanel_MouseMove 三个方法是用于实现点击鼠标右键并按住移动就能够移动窗体，Titlepanel_DoubleClick方法是实现双击时能够最大化或还原窗体功能。
最后的titlepanel_ControlRemoved与titlepanel_ControlAdded，实现的功能是当增加或移除按钮时，调整按钮的位置。
三、使用自定义窗体类
使用就比较简单了，先是新增一个窗体，然后将窗体类的父类由Form改为自定义窗体类（ZForm）即可，然后再切换到设计视图页面，是不是发现界面已经变化了呢，这时候就可以依据的想法灵活设置窗体标题栏样式，如下图：
public partial class Form1 : ZControls.ZForm
{
public Form1()
{
InitializeComponent();
}
}
将MaximizeBox设为False时，运行的效果，是不是有点爽啊！
好了，都说完了，其实也很简单，我相信大部份高手都是不屑一看的，但此处只是作为一个学习与参考，可能大家有更好的方法，欢迎大家交流，共同进步。
最后我上传源码，仅大家参考与改进：
