当窗体边框样式（FormBorderStyle）为None时带来的不便及解决方案

Winform窗口拖拽

当默认的窗口样式已经无法满足要求时，通常会将FormBorderSyle设置为None,随之带来的问题则是无法拖动窗口，非常的不方便
这里是用panel做为标题栏，用于拖动窗口，拖动窗口代码只需在窗口构造函数中添加即可

如何启用窗口拖拽

/// <summary>
/// 启用窗口拖拽
/// </summary>
/// <param name="form">父类窗体</param>
/// <param name="control">子类控件（拖拽应用对象）</param>
private void EnableTitleBarDrag(Form form, Control control)
{
    
    
    Point curP = new Point(0, 0);
    control.MouseDown += delegate (object sender, MouseEventArgs e)
      {
    
    
          control.Cursor = Cursors.SizeAll;
          curP = new Point(e.X, e.Y);
          control.MouseMove += Moved;
      };
    control.MouseUp += delegate (object sender, MouseEventArgs e)
    {
    
    
        control.Cursor = Cursors.Default;
        control.MouseMove -= Moved;
    };

    void Moved(object sender, MouseEventArgs e)
    {
    
    
        form.Location = new Point(form.Location.X + (e.X - curP.X), form.Location.Y + (e.Y - curP.Y));
    }
}

这样就窗体就可以任意拖拽了
