图标存在于系统托盘中？
我想检查系统托盘中是否存在图标; 如果“X”应用程序在系统托盘区域中显示了其系统托盘图标。
我已经谷歌了解如何做到这一点的信息，但我没有找到任何东西。
更新：
这是我在VB.NET中尝试翻译Robert评论给出的URL的C＃示例，但我不知道如何继续。
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
