圖標存在於系統托盤中？

Question

我想檢查系統托盤中是否存在圖標;如果「X」應用程序在系統托盤區域中顯示了其系統托盤圖標。

我已經谷歌瞭解如何做到這一點，但我沒有找到任何信息。

UPDATE：

這是我在VB.NET已經試過紅粉羅伯特評論翻譯網址的C＃的例子，但我不知道該怎麼繼續下去。

Imports System.Runtime.InteropServices 

Public Class Form1 

    Public Declare Function FindWindow Lib "user32.dll" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long 
    Public Declare Function FindWindowEx Lib "user32.dll" Alias "FindWindowExA" (ByVal hWndParent As IntPtr, ByVal hWndChildAfter As IntPtr, ByVal lpClassName As String, ByVal lpWindowName As String) As IntPtr 

    Public Shared Function WindowHandle(sTitle As String) As Long 
     Return FindWindow(vbNullString, sTitle) 
    End Function 


    Private Shared Function GetSystemTrayHandle() As IntPtr 
     Dim hWndTray As IntPtr = FindWindow("Shell_TrayWnd", Nothing) 
     If hWndTray <> IntPtr.Zero Then 
      hWndTray = FindWindowEx(hWndTray, IntPtr.Zero, "TrayNotifyWnd", Nothing) 
      If hWndTray <> IntPtr.Zero Then 
       hWndTray = FindWindowEx(hWndTray, IntPtr.Zero, "SysPager", Nothing) 
       If hWndTray <> IntPtr.Zero Then 
        hWndTray = FindWindowEx(hWndTray, IntPtr.Zero, "ToolbarWindow32", Nothing) 
        Return hWndTray 
       End If 
      End If 
     End If 

     Return IntPtr.Zero 
    End Function 

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click 
     MsgBox(WindowHandle("Steam")) ' 6687230 
     MsgBox(GetSystemTrayHandle()) ' 62789 
    End Sub 

End Class
