通过鼠标拖动移动无框窗口窗体

我是c#的新手，我在StackExchange上尝试了许多解决方案，我没有运气试图设置一个控件或整个窗体来左键点击并拖动整个窗口。我正在visual studio 12中使用无框窗口。我最接近移动窗口是移动一个控件与pastebin组件(最后的响应)从这个-我如何使鼠标拖动面板内移动窗体窗口?我只能让面板本身随着组件移动。

我已经尝试了大多数方法，但我似乎迷失了我在哪里定制它到我自己的需要。我已经尝试过重写WndProc，但它没有做任何当我试图移动窗体窗口。

我有两个面板，我希望能够拖动窗口与DragPanel和DragPanel2。

这是我最近尝试使用整个表单的失败方法。

如何将面板设置为左键拖动窗口?

我已经尝试了上面的所有方法和这里的WndProc方法:鼠标拖动无边框窗口窗体

private void Form1_MouseMove(object sender, MouseEventArgs e)
{
   if (e.Button == MouseButtons.Left)
   {
      ReleaseCapture();
      SendMessage(Handle, WM_NCLBUTTONDOWN, HT_CAPTION, 0);
   }
}

Point prevpoint=new Point(0,0);
Point offset=new Point(0,0);
private void Form1_MouseMove(object sender, MouseEventArgs e)
{
   if (e.Button == MouseButtons.Left)
   {
      offset.X=e.X-prevpoint.X;
      offset.Y=e.Y-prevpoint.Y;
      prevpoint.X=e.X;
      prevpoint.Y=e.Y;
      this.Location = new Point(this.Location.X + offset.X, this.Location.Y + offset.Y);
   }
}
