支持所有版本。

Powershell能夠使用.net靜態方法，比如下面有一些你常用的方法：

復制代碼代碼如下:

[Math]::Round(7.9)
 
[Convert]::ToString(576255753217, 8)
 
[Guid]::NewGuid()
 
[Net.Dns]::GetHostByName('schulung12')
 
[IO.Path]::GetExtension('c:/test.txt')
 
[IO.Path]::ChangeExtension('c:/test.txt', 'bak')

要獲得更多的方法，你可以刪掉方括號后面的代碼，再添加兩個冒號，這時在Powershell_ISE中將會彈出這個類所有可選的方法及屬性。在Powershell控制臺中，你也可以使用TAB來獲取選擇方法屬性。

當然你也可以通過管道符查看他所有類型：
