关于C#窗体如何实现QQ的靠边停靠的方法，有好多人问到，在这里我把ta写下，希望能帮到一些学弟学妹做UI的时候，想加一些效果的。当时我是这样写的，还有比我的代码质量更好方法，大家不嫌麻烦的话，感兴趣的可以去尽情的搜索，毕竟360搜索起来了0.0
下面试代码，大家可以先看看，不懂的留言，或者你有更好的给我发个地址，我改正一下，谢谢大家！
代码：
窗体中添加定时器控件。
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
this.TopMost = true;
Timer checkDockTimer = new Timer();
checkDockTimer.Tick += new EventHandler(Timer1_Tick);
checkDockTimer.Interval = 100;
checkDockTimer.Enabled = true;
}
internal AnchorStyles StopAanhor = AnchorStyles.None;
private void Timer1_Tick(object sender, EventArgs e)
{
if (this.Bounds.Contains(Cursor.Position))
{
switch (this.StopAanhor)
{
case AnchorStyles.Top: this.Location = new Point(this.Location.X, 0);
break;
case AnchorStyles.Left: this.Location = new Point(0, this.Location.Y);
break;

新建类FormAutoDock：
public class FormAutoDock
{
public static void SideHideOrShow(Form DockableForm, ref int DockFormHeight, Timer _dockTimer)
{
if (DockableForm.WindowState != FormWindowState.Minimized)
{
_dockTimer.Interval = 1500;
if (Cursor.Position.X > DockableForm.Left - 1 && Cursor.Position.X < DockableForm.Right && Cursor.Position.Y > DockableForm.Top - 1 && Cursor.Position.Y < DockableForm.Bottom)
{
if (DockableForm.Top <= 0 && DockableForm.Left > 5 && DockableForm.Left < Screen.PrimaryScreen.WorkingArea.Width - DockableForm.Width)
{
DockableForm.Top = 0;
}
else if (DockableForm.Left <= 0)
{
DockableForm.Left = 0;
}
else if (DockableForm.Left + DockableForm.Width >= Screen.PrimaryScreen.WorkingArea.Width)
{
DockableForm.Left = Screen.PrimaryScreen.WorkingArea.Width - DockableForm.Width;
}
else
{
if (DockFormHeight > 0)
{
DockableForm.Height = DockFormHeight; DockFormHeight = 0;
}
}
}
else
{
if (DockFormHeight < 1)
{
DockFormHeight = DockableForm.Height;
}
if (DockableForm.Top <= 4 && DockableForm.Left > 5 && DockableForm.Left < Screen.PrimaryScreen.WorkingArea.Width - DockableForm.Width)
{
DockableForm.Top = 3 - DockableForm.Height;
if (DockableForm.Left <= 4)
{
DockableForm.Left = -5;
}
else if (DockableForm.Left + DockableForm.Width >= Screen.PrimaryScreen.WorkingArea.Width - 4)
{
DockableForm.Left = Screen.PrimaryScreen.WorkingArea.Width - DockableForm.Width + 5;
}
}
else if (DockableForm.Left <= 4)
{
DockableForm.Left = 3 - DockableForm.Width;
}
else if (DockableForm.Left + DockableForm.Width >= Screen.PrimaryScreen.WorkingArea.Width - 4)
{
DockableForm.Left = Screen.PrimaryScreen.WorkingArea.Width - 3;
}
_dockTimer.Interval = 200;
}
}
}
}
