Convert an Array Object to a String in PowerShell Using Double Inverted CommasA straightforward approach to convert an array object into a string is by using double inverted commas (" ").Double inverted commas are used to denote strings in PowerShell. When applied to an array variable, this ...
如果未指定数据类型,PowerShell 会创建每个数组作为对象数组 (System.Object[])。 若要确定数组的数据类型,请使用 GetType() 方法。 例如:PowerShell 复制 $A.GetType() 若要创建强类型数组,即只能包含特定类型的值的数组,请将变量强制转换为数组类型,例如 string[]、long[]或int32[]。 若要强制转换数组,请...
$array = 1..5 | ForEach-Object { "ATX-SQL-$PSItem" } 通常,当我们考虑使用管道时,我们会想到典型的 PowerShell 单行命令。 可以通过 foreach() 语句和其他循环来利用管道。 因此,我们可以将项放到管道中,而不是在循环中向数组添加项。PowerShell 复制 ...
Step 4 – Output the object The only thing left to do now is to create a PowerShell object that contains the parsed data. Let’s put this all together. Copy functionparseNetstat{param([object[]]$Lines)if($IsWindows) {$skip=4}else{$skip=3}$Lines|Select-Object-Skip$skip|ForEach-Objec...
$string = $array.ForEach({ $_.ToString() }) -join "," 上述代码使用ForEach()方法遍历数组中的每个元素,并将每个元素转换为字符串。然后使用-join操作符将转换后的字符串连接起来。 使用-join操作符和ConvertTo-Json命令:在某些情况下,如果数组中的元素是复杂类型,如对象,可能希望将其转换为JSON格式...

IsPublic IsSerial Name BaseType --- --- --- --- True True String System.Object 如果在类型之后声明了验证属性,则会在类型转换之前验证所分配的值,这可能会导致意外的验证失败。 PowerShell 复制 [string] [ValidateLength(1,5)]$TicketIDFromInt = 43 [string] [ValidateLength(1,5)]...
$array变量包含一个 Int32 对象和一个 string 对象,如通过管道将数组传递给Get-Member时所示。 使用 InputObject 参数传递$array时,Get-Member返回 Object[] 类型的成员。 示例7:确定可以设置的对象属性 此示例演示如何确定对象的哪个属性可更改。 PowerShell ...
