这个可以实现，不过也需要在属性栏选定mouse 的3个对应行为，或者在**.Designer.cs中窗体部分加上

this.MouseDown += new System.Windows.Forms.MouseEventHandler(this.academyweekshow1_MouseDown);//还需加这3句
this.MouseMove += new System.Windows.Forms.MouseEventHandler(this.academyweekshow1_MouseMove);
this.MouseUp += new System.Windows.Forms.MouseEventHandler(this.academyweekshow1_MouseUp);[Quote=引用 1 楼的回复:]

C# code
Point mouseOff;//鼠标移动位置变量
bool leftFlag;//标签是否为左键
private void Form1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left……

protected override void WndProc(ref Message m)
{
if (m.Msg == 163 && this.ClientRectangle.Contains(this.PointToClient(new Point(m.LParam.ToInt32()))) && m.WParam.ToInt32() == 2)
m.WParam = (IntPtr)1;
base.WndProc(ref m);
if (m.Msg == 132 && m.Result.ToInt32() == 1)
m.Result = (IntPtr)2;
}

你的主窗体没被其他控件覆盖吧，我是用的picturebox，事件对应添加就行

添加窗体拖动事件处理或窗体的MouseDown事件处理。这样程序会首先把获得的事件发送给窗体而不是其它控件。在处理函数中添加拖动代码即可。

2楼正解,代码简洁。

(1)把代码复制进FORM的*.CS文件
(2)在属性窗口内，选择指定Form1_MouseDown事件．

为什么我拖不动窗体啊刚朋友给我的也是这段代码

调用API

    using System.Runtime.InteropServices;



    [DllImport("user32.dll")]

     public static extern bool ReleaseCapture();

    [DllImport("user32.dll")]

    public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);

   public const int WM_SYSCOMMAND = 0x0112;

   public const int SC_MOVE = 0xF010;

    public const int HTCAPTION = 0x0002; 



在空间的_MouseDown中加入如下代码:

    如:



    private void Form1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)

   {

    ReleaseCapture();

    SendMessage(this.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);

   }

                Location = mouseSet;

            }
