在你结束程序后面加上以下代码:

long hwnd = FindWindow("Shell_TrayWnd", NULL )
UpdateWindow(hwnd)
hwnd = FindWindowEx(hwnd, 0, "TrayNotifyWnd", NULL)
UpdateWindow(hwnd)

作用是强制刷新托盘区,被中止的进程自然就没有托盘图标了,
相关API声明如下:
Declare Function UpdateWindow Lib "user32" Alias "UpdateWindow" (ByVal hwnd As Long) As Long
Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long
Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long

哈哈,老兄,C#也是一样呀,API声明变一下就行了:
[DllImport("user32.dll", EntryPoint="UpdateWindow")]
public static extern int UpdateWindow (
int hwnd
);
[DllImport("user32.dll", EntryPoint="FindWindowEx")]
public static extern int FindWindowEx (
int hWnd1,
int hWnd2,
string lpsz1,
string lpsz2
);
[DllImport("user32.dll", EntryPoint="FindWindow")]
public static extern int FindWindow (
string lpClassName,
string lpWindowName
);
把前面的调用语句后面加上分号....还不行再问我吧.

退出程序的时候先把任务栏图标设置为不可见就可以了，关了就等垃圾回收。

死循环！

在主窗体关闭时Hide托盘，同时Dispose该托盘资源,就ok!
例如:
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
this.notifyIcon1.Visible = false;
this.notifyIcon1.Dispose();
}
