XmlNode类型。 System.String类实现IEnumerable,但 PowerShell 不枚举字符串对象。 在以下示例中,通过管道将数组和哈希表传递给Measure-Objectcmdlet,以计算从管道接收的对象数。 数组具有多个成员,哈希表具有多个键值对。 一次只枚举一个数组。 PowerShell复制 @(1,2,3) |Measure-
哈希表具有 Count 属性,指示 hashtable中的键值对数。 PowerShell 复制 $hash.count 3 hashtable 表不是数组,因此不能将整数用作 hashtable中的索引,但可以使用键名称为 hashtable编制索引。如果键是字符串值,请将键名称括在引号中。 例如: PowerShell 复制 $hash["Number"] 1 处理属性名称冲突 如果键...
