我使用c＃创建了一个无边框表单但可以使自定义标题栏移动，所以我搜索互联网并找到了这段代码：
protected override void WndProc(ref Message m)
{
base.WndProc(ref m);
if (m.Msg == WM_NCHITTEST)
m.Result = (IntPtr)(HT_CAPTION);
}
private const int WM_NCHITTEST = 0x84;
private const int HT_CLIENT = 0x1;
private const int HT_CAPTION = 0x2;
应用此代码后，可以在表单的每个字体中单击并拖动我的表单，但标题栏除外。

这是可移动标题栏的一个很好的例子 这是一个完整的例子
using System;
using System.Drawing;
using System.Windows.Forms;
namespace Custom_Title_Bar
{
public partial class MainForm : Form
{
private PictureBox title = new PictureBox(); // create a PictureBox
private Label minimise = new Label(); // this doesn't even have to be a label!
private Label maximise = new Label(); // this will simulate our this.maximise box
private Label close = new Label(); // simulates the this.close box
private bool drag = false; // determine if we should be moving the form
private Point startPoint = new Point(0, 0); // also for the moving
public MainForm()
{
this.FormBorderStyle = FormBorderStyle.None; // get rid of the standard title bar
this.title.Location = this.Location; // assign the location to the form location
this.title.Width = this.Width; // make it the same width as the form
this.title.Height = 50; // give it a default height (you may want it taller/shorter)
this.title.BackColor = Color.Black; // give it a default colour (or load an image)
this.Controls.Add(this.title); // add it to the form's controls, so it gets displayed
// if you have an image to display, you can load it, instead of assigning a bg colour
// this.title.Image = new Bitmap(System.Environment.CurrentDirectory + "\\title.jpg");
// if you displayed an image, alter the SizeMode to get it to display as you want it to
// examples:
// this.title.SizeMode = PictureBoxSizeMode.StretchImage;
// this.title.SizeMode = PictureBoxSizeMode.CenterImage;
// this.title.SizeMode = PictureBoxSizeMode.Zoom;
// etc
// you may want to use PictureBoxes and display images
// or use buttons, there are many alternatives. This is a mere example.
this.minimise.Text = "Minimise"; // Doesn't have to be
this.minimise.Location = new Point(this.Location.X+5, this.Location.Y+5); // give it a default location
this.minimise.ForeColor = Color.Red; // Give it a colour that will make it stand out
// this is why I didn't use an image, just to keep things simple:
this.minimise.BackColor = Color.Black; // make it the same as the PictureBox
this.Controls.Add(this.minimise); // add it to the form's controls
this.minimise.BringToFront(); // bring it to the front, to display it above the picture box
this.maximise.Text = "Maximise";
// remember to make sure it's far enough away so as not to overlap our minimise option
this.maximise.Location = new Point(this.Location.X+60, this.Location.Y+5);
this.maximise.ForeColor = Color.Red;
this.maximise.BackColor = Color.Black; // remember, we want it to match the background
this.maximise.Width = 50;
this.Controls.Add(this.maximise); // add it to the form
this.maximise.BringToFront();
this.close.Text = "Close";
this.close.Location = new Point(this.Location.X+120, this.Location.Y+5);
this.close.ForeColor = Color.Red;
this.close.BackColor = Color.Black;
this.close.Width = 37; // this is just to make it fit nicely
this.Controls.Add(this.close);
this.close.BringToFront();
// now we need to add some functionality. First off, let's give those labels
// MouseHover and MouseLeave events, so they change colour
// Since they're all going to change to the same colour, we can give them the same
// event handler, which saves time of writing out all those extra functions
this.minimise.MouseEnter += new EventHandler(Control_MouseEnter);
this.maximise.MouseEnter += new EventHandler(Control_MouseEnter);
this.close.MouseEnter += new EventHandler(Control_MouseEnter);
// and we need to do the same for MouseLeave events, to change it back
this.minimise.MouseLeave += new EventHandler(Control_MouseLeave);
this.maximise.MouseLeave += new EventHandler(Control_MouseLeave);
this.close.MouseLeave += new EventHandler(Control_MouseLeave);
// and lastly, for these controls, we need to add some functionality
this.minimise.MouseClick += new MouseEventHandler(Control_MouseClick);
this.maximise.MouseClick += new MouseEventHandler(Control_MouseClick);
this.close.MouseClick += new MouseEventHandler(Control_MouseClick);
// finally, wouldn't it be nice to get some moveability on this control?
this.title.MouseDown += new MouseEventHandler(Title_MouseDown);
this.title.MouseUp += new MouseEventHandler(Title_MouseUp);
this.title.MouseMove += new MouseEventHandler(Title_MouseMove);

如果您希望只提取移动代码并将其与代码集成，可移动的标题代码就在以下事件处理程序
中Title_MouseUp
Title_MouseDown
Title_MouseMove
