我正在尝试编写脚本以通过使用PowerShell刮擦网站来获取最新版本的citrix接收器。我已经到了最新版本，但是我无法正确地对它们进行降序排列，因为次要版本将9-1优先于99-10。
这是我的代码
$url = "https://www.citrix.com/downloads/citrix-receiver/"
$html = Invoke-WebRequest -Uri "$url"
$versionLinks = $html.Links | where innerHTML -Match "Receiver \d+(\.\d+)+.* for Windows$" | Sort-Object -Property innerHTML -Descending
$versionArray = @()
foreach ($version in $versionLinks){
[version]$VersionNumber = $version.innerHTML -split " " | Select -First 2 | select -Last 1
$versionArray += $VersionNumber
}
$versionArray = Sort-Object -InputObject $versionArray -Descending -Property minor
$LatestAppVersion = $versionArray[0]
$LatestAppVersion
它输出的是4.9。 $ versionArray看起来像
Major Minor Build Revision
----- ----- ----- --------
4 9 -1 -1
4 8 -1 -1
4 7 -1 -1
4 6 -1 -1
4 5 -1 -1
4 3 100 -1
4 12 -1 -1
4 11 -1 -1
4 10 1 -1
我希望成为
Major Minor Build Revision
----- ----- ----- --------
4 12 -1 -1
4 11 -1 -1
4 10 1 -1
4 9 -1 -1
4 8 -1 -1
4 7 -1 -1
4 6 -1 -1
4 5 -1 -1
4 3 100 -1
This question与我的相似。我正在使用排序版本，所以我不确定为什么会得到不同的结果。我确实尝试过使用[System.Version]，以防[version]不够具体。

如果使用，您会得到什么输出？

var $this = $(this),
$parent = $(this).parent();
if (e.type == 'rowselect') {
$('.clickable').slice(1).remove();
}
$parent.append($el);
}它应该产生您想要的输出
答案 1 :(得分：0)
当您按名称将数组传递给Sort-Object时，似乎-InputObject实际上没有任何作用，因此可以用管道将其代替：
$versionArray = $versionArray |Sort-Object -Descending -Property minor
答案 2 :(得分：0)
您确定要对未成年人进行排序吗？为什么不对整个版本进行排序？
代替：
$versionArray = $versionArray | Sort-Object -Descending -Property minor
考虑
$versionArray = $versionArray | Sort-Object -Descending
我将其作为答案提交并需要思考... 注意v3和v5测试用例
