PowerShell 中的实验性功能支持提供了一种机制,可便于实验性功能与 PowerShell 或 PowerShell 模块中的现有稳定功能共存。 实验性功能是指设计尚未最终确定的功能。 此类功能可供用户进行测试和提供反馈。 一旦实验性功能最终确定下来,设计变更就变成了中断性变更。 实验性功能不适合在生产环境中使用,因为允许变更...
可以从属性和属性值的哈希表创建对象。 语法如下所示: 复制 [<class-name>]@{ <property-name>=<property-value> <property-name>=<property-value> } 此方法仅适用于具有无参数构造函数的类。 对象属性必须是公共且可设置的。 PowerShell 版本 3.0 中添加了此功能 ...

Get-WmiObject-Class__Provider WMI 的三个组件 WMI 的以下三个组件与 Windows PowerShell 交互:命名空间、提供程序和类。 WMI 命名空间将 WMI 提供程序和 WMI 类组织成相关组件的组。 这样,它们就类似于 .NET Framework 命名空间。 命名空间不是物理位置,而更像是逻辑数据库。 所有 WMI 命名空间都是 __Name...
To create a constructor (overloaded or otherwise) in a Windows PowerShell 5.0 class, I need to remember that I am really creating a method. The method has thesame nameas the class name. When I do this, I have a constructor. For example, I want to add a constructor to myCarclass (...
Now you understand how to override inheritance in Windows PowerShell 5.0 classes. Windows PowerShell 5.0 Class Week 2 will continue tomorrow when I will present a video recap about overloaded constructors. I invite you to follow me onTwitterandFacebook. If you have any questions, send email to...
[<class-name>]@{ <property-name>=<property-value> <property-name>=<property-value> } This method works only for classes that have a constructor that has no parameters. The object properties must be public and settable. For more information, seeabout_Object_Creation. ...

Inheritance implementation is defined by the:operator; which means to extend this class or implements these interfaces. The derived class should always be leftmost in the class declaration. Example using simple inheritance syntax This example shows the simple PowerShell class inheritance syntax. ...
