c#winform自定义窗体(含源码)

第一步：首先引用DLL

再窗体中继承DevComponents.DotNetBar.OfficeForm

public partial class MainForm : DevComponents.DotNetBar.OfficeForm

初始化程序中添加 this.EnableGlass = false;

public MainForm() { this.EnableGlass = false; InitializeComponent(); }

第二步：重绘标题栏

this.FormBorderStyle = FormBorderStyle.None;

先将原生窗体设置成无边框，FormBoderStyle设置成None
然后添加一个panpel控件设置成窗体的的标题栏，并将panel的dock属性设置为Top；

然后添加四个labell控件充当标题和最小化最大化关闭按钮。

此时界面的原型就出来了。

第三步：最小最大关闭事件

注册事件

this.panelEx1.MouseDown += panel1_MouseDown; this.MouseDown += MainForm_MouseDown;

为事件添加处理方法

private void MinFormLabel_Click(object sender, EventArgs e) {
this.WindowState = FormWindowState.Minimized; }
private void MaxFormLabel_Click(object sender, EventArgs e) { if (this.WindowState != FormWindowState.Maximized) { this.WindowState = FormWindowState.Maximized; } else { this.WindowState = FormWindowState.Normal; } }
private void CloseFormLabel_Click(object sender, EventArgs e) { this.Close(); }

第四步：窗体拖动

[DllImport("user32.dll")] public static extern bool ReleaseCapture(); [DllImport("user32.dll")] public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam); private const int VM_NCLBUTTONDOWN = 0XA1;//定义鼠标左键按下 private const int HTCAPTION = 2; private void MainForm_MouseDown(object sender, MouseEventArgs e) { //为当前应用程序释放鼠标捕获 ReleaseCapture(); //发送消息 让系统误以为在标题栏上按下鼠标 SendMessage((IntPtr)this.Handle, VM_NCLBUTTONDOWN, HTCAPTION, 0); } private void panel1_MouseDown(object sender, MouseEventArgs e) { //为当前应用程序释放鼠标捕获 ReleaseCapture(); //发送消息 让系统误以为在标题栏上按下鼠标 SendMessage((IntPtr)this.Handle, VM_NCLBUTTONDOWN, HTCAPTION, 0); }

运行结果如下：
