本文实例为大家分享了WinForm实现鼠标拖动控件跟随效果的具体代码，供大家参考，具体内容如下

1. 运行初始窗口如下:

2. 拖动后效果如下:

3. 代码如下:

public partial class Form1 : Form
{
  

  /// 

  /// 鼠标按下为true
  /// 
  private bool Mousedown;

  /// 

  /// 鼠标在事件源的位置
  /// 
  private int CurX = 0;
  private int CurY = 0;

  public Form1()
  {
    InitializeComponent();
  }

  private void Controls_MouseDown(object sender, MouseEventArgs e)
  {
    CurX = e.X;
    CurY = e.Y;
    Mousedown = true;
    if (sender is TextBox)
    {
      ((TextBox)sender).Cursor = Cursors.Arrow;
    }
  }

  private void Controls_MouseMove(object sender, MouseEventArgs e)
  {
    if (Mousedown)
    {
      // 获取当前屏幕的光标坐标
Point pTemp = new Point(Cursor.Position.X, Cursor.Position.Y);
      // 转换成工作区坐标
pTemp = this.PointToClient(pTemp);
      // 定位事件源的 Location
      Control control = sender as Control;
      control.Location = new Point(pTemp.X - CurX, pTemp.Y - CurY); 
    }
  }

  private void Controls_MouseUp(object sender, MouseEventArgs e)
  {
    Mousedown = false;
    if (sender is TextBox)
    {
      ((TextBox)sender).Cursor = Cursors.IBeam;
