[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 &lt;= 0 &amp;&amp; this.Left &lt;= 0)

{

StopAanhor = AnchorStyles.None;

}

else if (this.Top &lt;= 0)

{

StopAanhor = AnchorStyles.Top;

}

//else if (this.Left &lt;= 0)             //{             //    StopAanhor = AnchorStyles.Left;             //}             else if (this.Left &gt;= Screen.PrimaryScreen.Bounds.Width - this.Width)

{

StopAanhor = AnchorStyles.Right;

}

else if (this.Top &gt;= 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;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

namespace WindowsFormsApplication2

{

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;

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;

}

}

}

internal AnchorStyles StopAanhor = AnchorStyles.None;

private void mStopAnhor()

{

if (this.Top &lt;= 0 &amp;&amp; this.Left &lt;= 0)

{

{

}

//else if (this.Left &lt;= 0) //{ // StopAanhor = AnchorStyles.Left; //} else if (this.Left &gt;= Screen.PrimaryScreen.Bounds.Width - this.Width)

{

StopAanhor = AnchorStyles.Right;

}

else if (this.Top &gt;= Screen.PrimaryScreen.Bounds.Height - this.Height)

{

StopAanhor = AnchorStyles.Bottom;

}

else

{

StopAanhor = AnchorStyles.None;

}

}

private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs 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;

}

}

//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();

}

private void Form1_SizeChanged(object sender, EventArgs e)

{

if (this.WindowState == FormWindowState.Minimized)

{

this.Hide();

}

}

}

}

另附Form1.Designer.cs代码供参考：
