7zip实用的最新版本？

Question

我想将客户端计算机上安装的7zip.exe版本与最新发布的版本进行比较。

目前，我可以通过从页面URL https://www.7-zip.org/download.html下载源代码来获取最新版本号。

这是我的代码。 是否有任何API（似乎没有可用的API）/其他更好的解决方案以编程方式读取7zip最新版本？

Dim sourceString As String = New System.Net.WebClient().DownloadString("https://www.7-zip.org/download.html")

这是一种方法，但是很容易发生变化

Private Function GetInstalledVersion() As Single
    Dim version As Single = Nothing
    Using root = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64)
        Using key = root.OpenSubKey("Software\7-Zip", False)
            Dim appPath As String = CStr(key.GetValue("Path"))
            Dim appVersion = FileVersionInfo.GetVersionInfo(Path.Combine(appPath, "7z.exe"))
            If Not Single.TryParse(appVersion.ProductVersion, version) Then
                Console.WriteLine("Unable to retrieve installed version")
            End If
            Return version
        End Using
    End Using
End Function

Private Function GetWebVersion() As Single
    Dim r As Regex = New Regex("(?<=Download 7-Zip ).*?(?= )")
    Dim web = New Net.WebClient().DownloadString("https://www.7-zip.org/download.html")
    Dim version As Single = Nothing
    If Not Single.TryParse(r.Match(web).Value, version) Then
        Console.WriteLine("Unable to retrieve web version")
    End If
    Return version
End Function
