Powershell将字符串转换为数组

Question

How do I change:

$Text = "Apple Pear Peach Banana"

to

$Text = @("Apple", "Pear", "Peach", "Banana")

I am planning to feed the array to a foreach loop. The input the user is prompted to enter fruit with a space between (I will use Read-Host for that). So then I need to convert a space-separated string to an array for the foreach loop.

Thank you...

Answer 1

I would use the -split regex operator , like so:

$text = -split $text

You can also use it directly in the foreach() loop declaration:

foreach($fruit in -split $text)
{
    "$fruit is a fruit"
}

---

In unary mode (like above), -split defaults to splitting on the delimeter \\s+ (1 or more whitespace characters).

This is nice if a user accidentally enters consecutive spaces:

PS C:\> $text = Read-Host 'Input fruit names'
Input fruit names: Apple Pear   Peaches  Banana
PS C:\> $text = -split $text
PS C:\> $text
Apple
Pear
Peaches
Banana

Answer 2

使用Split（）

$text = $text.Split(" ")

Answer 3

$Text.Split(' ')

need more characters for answer.

Answer 4

$text = $text -split " "

如果你的水果名字都不是你想要保持在一起的两个单词，那就行了。
