WinForm界面下怎么拖动控件

WinForm界面上如何拖动控件？
做一个类似VS的东西，能够在界面上用鼠标点击的方式添加控件，添加的控件可以拖动，以更改位置...应该怎么弄呢？或者哪位高手 有一些这样的小玩意..给我发一下QQ317648720 谢谢了

你看看VS里面有一个叫什么visualstdio.desinger类的.
具体忘了,你查一下,专门介绍做类似VS的东西

C# code

using System;using System.Runtime.InteropServices;using System.Windows.Forms;namespace WindowsFormsApplication4{    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        [DllImport("user32.dll")]        static extern bool ReleaseCapture();        [DllImport("user32.dll", CharSet = CharSet.Auto)]        static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, UInt32 wParam, UInt32 lParam);        private readonly UInt32 WM_SYSCOMMAND = 0x112;        private readonly UInt32 SC_MOVE = 0xF010;        private readonly UInt32 HTCAPTION = 2;        private void button1_MouseDown(object sender, MouseEventArgs e)        {            ReleaseCapture();            SendMessage(button1.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);        }        private void pictureBox1_MouseMove(object sender, MouseEventArgs e)        {            ReleaseCapture();            SendMessage(pictureBox1.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);        }        private void textBox1_MouseDown(object sender, MouseEventArgs e)        {            ReleaseCapture();            SendMessage(textBox1.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);        }    }}

你去下载个sharpdevelop
那是仿VS软件，还是开源的
