$myarray = [System.Collections.ArrayList]::new() [void]$myArray.Add('Value') 我们正在调用 .NET 以获取此类型。 在本例中,我们将使用默认构造函数来创建它。 然后调用 Add 方法向其中添加项。我在行首使用 [void] 是为了禁用返回代码。 某些 .NET 调用会这么做,并可能会产生意外输出。如果数组中的唯一...

True True Object[] System.Array $item为一个对象数组 动态和静态类型 一般对PowerShell变量重新赋值时,变量类型会自动改变,这体现了动态语言的特点; 而同样使用.NET 的C#却是静态强类型的语言,既然很像C#因此PowerShell也可以使用静态类型,静态类型带来的严谨性能避免不必要的错误。

相反,使用Set-Content,Add-Content和Out-File这几条命令,而不使用重定向,可以有效地规避前面的风险。这三条命令都支持-encoding参数,你可以用它来选择字符集。 创建新驱动器 你可能会惊讶,PowerShell允许你创建新的驱动器。并且不会限制你只创建基于网络的驱动器。你还可以使用驱动器作为你的文件系统中重要目录,...
A PowerShell array is a component that enables the storage of more than one item in a variable or a field. For instance, to assign multiple values to a variable, use the script$a=1,2,3. PowerShell treats each item in an array as a separate element. To address each item in an arra...
The start and end values of the range can be any pair of expressions that evaluate to an integer or a character. The endpoints of the range must be convertible to signed 32-bit integers ([int32]). Larger values cause an error. Also, if the range is captured in an array, the size ...
