[转载]C#实现窗口贴边自动隐藏、任务栏隐藏至托盘并添加双击和右键菜单 – madebychina – 博客园.
开发环境：Windows7系统，Visual Studio 2010专业版，.Net Framework 2.0。
一、Winform窗体贴边自动隐藏
新建Windows窗体应用程序，向Form1窗体中添加一个Timer控件，设定其Interval属性值为50，并为其添加Tick事件。代码为：
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;
case AnchorStyles.Right:
this.Location = new Point(Screen.PrimaryScreen.Bounds.Width - this.Width, this.Location.Y);
break;
case AnchorStyles.Bottom:
this.Location = new Point(this.Location.X, Screen.PrimaryScreen.Bounds.Height - this.Height);
break;
}
}
else
{
switch (this.StopAanhor)
{
case AnchorStyles.Top:
this.Location = new Point(this.Location.X, (this.Height - 4) * (-1));
break;
case AnchorStyles.Left:
this.Location = new Point((-1) * (this.Width - 4), this.Location.Y);
break;
case AnchorStyles.Right:
this.Location = new Point(Screen.PrimaryScreen.Bounds.Width - 4, this.Location.Y);
break;
case AnchorStyles.Bottom:
this.Location = new Point(this.Location.X, (Screen.PrimaryScreen.Bounds.Height - 4));
break;
}
}
}
添加如下变量和函数：
internal AnchorStyles StopAanhor = AnchorStyles.None;
private void mStopAnhor()
{
if (this.Top <= 0 && this.Left <= 0)
{
StopAanhor = AnchorStyles.None;
}
else if (this.Top <= 0)
{
StopAanhor = AnchorStyles.Top;
}
//else if (this.Left <= 0) //{ // StopAanhor = AnchorStyles.Left; //} else if (this.Left >= Screen.PrimaryScreen.Bounds.Width - this.Width)
{
StopAanhor = AnchorStyles.Right;
}
else if (this.Top >= Screen.PrimaryScreen.Bounds.Height - this.Height)
{
StopAanhor = AnchorStyles.Bottom;
}
else
{
StopAanhor = AnchorStyles.None;
}
}
为Form1窗体添加Load事件，代码为：
private void Form1_Load(object sender, EventArgs e)
{
this.TopMost = true;
this.timer1.Start();
}
为Form1窗体添加LocationChangeD事件，代码为：
private void Form1_LocationChanged(object sender, EventArgs e)
{
this.mStopAnhor();
}
至此，WinForm窗体的自动贴边隐藏效果完成，该效果可以实现窗体上下右四个方位的贴边隐藏。
（如果想实现窗体上下左右四个方位的贴边隐藏，请将上面的
//else if (this.Left <= 0)
//{
// StopAanhor = AnchorStyles.Left;
//}
注释去掉，但是这样做会影响之后的窗体还原效果）
二、托盘图标、自动隐藏任务栏图标、托盘图标双击事件、托盘图标右键菜单
继续向Form1窗体中添加一个NotifyIcon控件，并为其添加一个图标。
为NotifyIcon控件添加MouseDoubleClick事件，代码如下：
private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
{
this.Show();
this.WindowState = FormWindowState.Normal;
this.Activate();
}
（也可添加MouseClick事件，内部代码同上，但是会有我们不希望看到的效果，当你使用右键单击托盘图标想要弹出右键菜单时，也会触发该事件，C#好像并没有区分鼠标的左右键，不知道为什么）
再向Form1窗体添加一个ContentMenuStrip控件，并为其添加两个MenuItem子菜单项，Text分别为“还原”、“关闭”（可为每个子菜单项添加小图标，自便），为两个子菜单项添加Click事件，代码如下：
//还原
private void toolStripMenuItem1_Click(object sender, EventArgs e)
{
this.Show();
this.WindowState = FormWindowState.Normal;
this.Activate();
}
//关闭
private void toolStripMenuItem2_Click(object sender, EventArgs e)
{
timer1.Enabled = false;
this.notifyIcon1.Visible = false;
this.Close();
this.Dispose();
Application.Exit();
}
为Form1窗体添加SizeChanged事件，代码如下：
private void Form1_SizeChanged(object sender, EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
this.Hide();
}
}
最后向Form1的Load事件中添加如下代码：
this.notifyIcon1.Visible = true;
this.ShowInTaskbar = false;
this.notifyIcon1.ContextMenuStrip = contextMenuStrip1;
到此题目所列效果均已实现，但是当窗口处于贴边隐藏状态时，我们双击托盘图标，或者右键托盘菜单还原窗口时，窗口并没有从隐藏状态变为显示状态，与我们的使用习惯不太一致。这是我们可以在NotifyIcon的MouseDoubleClick事件和右键还原菜单项的Click事件中添加如下代码：
this.timer1.Interval = 2000;
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;
case AnchorStyles.Right:
this.Location = new Point(Screen.PrimaryScreen.Bounds.Width - this.Width, this.Location.Y);
break;
case AnchorStyles.Bottom:
this.Location = new Point(this.Location.X, Screen.PrimaryScreen.Bounds.Height - this.Height);
break;
}
并且在Timer空间的Tick事件中添加下面一句代码：
this.timer1.Interval = 50;
此种方法定有不妥之处，但限于水平，只能委屈于此了。
现附Form1.cs的完整代码如下：
using System;
using System.Collections.Generic;

this.timer1.Start();
this.notifyIcon1.Visible = true;
this.ShowInTaskbar = false;
this.notifyIcon1.ContextMenuStrip = contextMenuStrip1;
}
private void Form1_LocationChanged(object sender, EventArgs e)
{
this.mStopAnhor();
}
private void timer1_Tick(object sender, EventArgs e)
{
this.timer1.Interval = 50;
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;

break;

this.Location = new Point(this.Location.X, Screen.PrimaryScreen.Bounds.Height - this.Height);
break;
}
}
else
{

{
case AnchorStyles.Top:
this.Location = new Point(this.Location.X, (this.Height - 4) * (-1));
break;

break;

}
}

{

}
private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
{

this.WindowState = FormWindowState.Normal;
this.Activate();
this.timer1.Interval = 2000;
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;
case AnchorStyles.Right:
this.Location = new Point(Screen.PrimaryScreen.Bounds.Width - this.Width, this.Location.Y);
break;
case AnchorStyles.Bottom:
this.Location = new Point(this.Location.X, Screen.PrimaryScreen.Bounds.Height - this.Height);
break;
}
}
//还原-
private void toolStripMenuItem1_Click(object sender, EventArgs e)
{
this.Show();
this.WindowState = FormWindowState.Normal;
this.Activate();
this.timer1.Interval = 2000;
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;
case AnchorStyles.Right:
this.Location = new Point(Screen.PrimaryScreen.Bounds.Width - this.Width, this.Location.Y);
break;
case AnchorStyles.Bottom:
this.Location = new Point(this.Location.X, Screen.PrimaryScreen.Bounds.Height - this.Height);
break;
}
}
//关闭
private void toolStripMenuItem2_Click(object sender, EventArgs e)
{
timer1.Enabled = false;
this.notifyIcon1.Visible = false;
this.Close();
this.Dispose();
Application.Exit();
}
