C#中怎么实现窗体无标题栏拖动

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace MoveForm
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private bool isMouseDown = false;
private Point FormLocation; //form的location
private Point mouseOffset; //鼠标的按下位置

private void Form1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
isMouseDown = true;
FormLocation = this.Location;
mouseOffset = Control.MousePosition;
}
}

private void Form1_MouseUp(object sender, MouseEventArgs e)
{
isMouseDown = false;
}

private void Form1_MouseMove(object sender, MouseEventArgs e)
{
int _x = 0;
int _y = 0;
if (isMouseDown)
{
Point pt = Control.MousePosition;
_x = mouseOffset.X - pt.X;
_y = mouseOffset.Y - pt.Y;

this.Location = new Point(FormLocation.X - _x, FormLocation.Y - _y);
}
}
}
}

用窗体的MouseDown，MouseMove，MouseUp三个事件

这个嘛，没试过。帮你顶下！关注中.....
