我试图在Windows 2008 Server上运行脚本，但不确定是否可以运行它。我收到以下错误消息：
Unable to find type [System.Net.Webutility]: make sure that the assembly containing this type is loaded.
如上所述，我试图在2008 Server上运行它。根据System.Net.Webutility文档，它自Windows 8以来一直可用。我是SOL还是有解决方法？
以下是我的代码：

System.Web.HttpUtility.HtmlDecode已经可用，因此您可以选择完成相同的操作：
Add-Type -AssemblyName System.Web;
$encoded = '<span class="c2">FRIDAY </span>';
[System.Web.HttpUtility]::HtmlDecode($encoded);

修复：安装Windows Management Framework 5.1以获取PowerShell 5.1，但请注意，这是系统范围的更改，某些软件（特别是Exchange）不支持更改PowerShell版本。
解决方法：您的代码仅使用它来执行单个HTMLDecode，这不是一个非常复杂的操作;对于.Net Core中的那个方法here is the source code，所以要么在C＃中以某种方式内联，要么将其移植到PowerShell。
我做了什么，并且花了我很长的时间 - 让我开始“不是一个非常复杂的操作”，我没有意识到它必须处理多字节unicode，并且有内存性能优化查找表和他们发生冲突的PowerShell字符串处理等;）但这里是：
[char]$HIGH_SURROGATE_START = 0xD800

[int]$UNICODE_PLANE01_START = 0x10000
[int]$UNICODE_PLANE16_END = 0x10FFFF

[uint64]$key = 0
for ($i = 0; $i -lt $entity.Length; $i++)
{
if ($entity[$i] -gt 0xFF)
{
return 0
}
$key = ($key -shl 8) -bor $entity[$i]
}
$key
}
# To avoid an allocation, keys of type "ulong" are used in the lookup table.
# Since all entity strings comprise 8 characters or less and are ASCII-only, they "fit" into an ulong (8 bytes).
