Powershell中可以使用的.Net實(shí)用靜態(tài)方法

更新時(shí)間：2015年03月26日 08:57:23 投稿：junjie

這篇文章主要介紹了Powershell中可以使用的.Net實(shí)用靜態(tài)方法,本文直接給出使用示例,并羅列了常用的靜態(tài)方法,需要的朋友可以參考下

支持所有版本。

Powershell能夠使用.net靜態(tài)方法，比如下面有一些你常用的方法：

[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(hào)后面的代碼，再添加兩個(gè)冒號(hào)，這時(shí)在Powershell_ISE中將會(huì)彈出這個(gè)類(lèi)所有可選的方法及屬性。在Powershell控制臺(tái)中，你也可以使用TAB來(lái)獲取選擇方法屬性。

當(dāng)然你也可以通過(guò)管道符查看他所有類(lèi)型：

復(fù)制代碼代碼如下:
