When no data type is specified, PowerShell creates each array as an object array (System.Object[]). To determine the data type of an array, use the GetType() method. For example:PowerShell Copy $A.GetType() To create a strongly typed array, that is, an array that can contain only...

createArray(<inputValue>) 说明 函数createArray()从输入值返回值数组。 可以使用此函数创建任何类型的数组。 输入值的类型必须相同 - 数字、字符串、对象或数组。 当输入值为对象或数组时,它们不需要是具有相同属性或相同类型的数组的对象。 当输入值为数组时,函数将返回数组数组。
另一個範例涉及 Array 類型(§4.3.2),其中包含一組稱為 Copy 的方法,這些方法會從一個陣列中複製元素到另一個陣列,從每個陣列的開頭(預設)或在某些指定的元素開始。 該集合中的方法具有下列簽章: PowerShell 複製 Copy(Array, Array, int) Copy(Array, Array, long) Copy(Array, int, Array, int, int...

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。
