在PowerShell中将字符串转换为int数组 [英] Convert string to int array in PowerShell

问题描述

我正在尝试转换一个看起来像这样的字符串，

I'm trying to convert a string that looks like this,

    2,3,4,5,6,20..30

到一个整数数组.这是我目前拥有的代码:

to an array of integers. Here is the code I currently have:

[string]$a = "2,3,4,5,6,7"
[array]$b = $a.split(",")
[array]$c = foreach($number in $b) {([int]::parse($number))}

哪个有效，但不适用于 20..30 的范围.我如何让那部分工作?

Which works, but not for the range of 20..30. How do I get that part working?

推荐答案

您可以使用 Invoke-Expression cmdlet 来解释 10..30 位，如果[int]::Parse() 方法调用失败.

You can use the Invoke-Expression cmdlet to interpret the 10..30 bit, if the [int]::Parse() method call fails.

这是一个完整的工作示例.

Here is a complete, working sample.

[string]$a = "2,3,4,5,6,7,10..30";
[array]$b = $a.split(",");
[array]$c = foreach($number in $b) {
    try {
        [int]::parse($number)
    }
    catch {
        Invoke-Expression -Command $number;
    }
    }

$c;
