c# - 图标存在于系统托盘中？

Question

我想检查系统托盘中是否存在图标；例如，如果“X”应用程序在系统托盘区域中显示了它们的系统托盘图标。

我在谷歌上搜索了有关如何执行此操作的信息，但没有找到任何内容。

UPDATE :

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
