支持所有版本。

Powershell能够使用.net静态方法，比如下面有一些你常用的方法：
复制代码 代码如下:
[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')

要获得更多的方法，你可以删掉方括号后面的代码，再添加两个冒号，这时在Powershell_ISE中将会弹出这个类所有可选的方法及属性。在Powershell控制台中，你也可以使用TAB来获取选择方法属性。

当然你也可以通过管道符查看他所有类型：
复制代码 代码如下:
