逐行读取文件并拆分值 [英] Read line-by-line file and split values

问题描述

我需要读取一个组成如下的txt文件:

I need to read a txt file composed as follow:

      AA=1000,AA=320009#999999

      AA=1011,AA=320303#111111

对于每条阅读的行，我需要用#"将其拆分以在第一回合获得

for each readed line I need to split it by "#" to get at the first turn

 $test[0] = AA=1000,AA=320009 and $test[1]=999999

然后在第二个转弯处

 $test[0] = AA=1000,AA=320003   $test[1]= 1111111

我在理解如何使用 get-content 或获取它时遇到了一些问题.

I have some problems to understand how to use get-content or to get it.

推荐答案

# Basically, Get-Content will return you an array of strings such as below:
# $tests = Get-Content "c:\myfile\path\mytests.txt"

$tests = @(
    "AA=1000,AA=320009#999999",
    "AA=1011,AA=320303#111111"
)

$tests | %{ $test = $_ -split '#'; Write-Host $test[0]; Write-Host $test[1] }

上一行相当于:

$tests | foreach {
  $test = $_ -split '#'
  Write-Host $test[0]
  Write-Host $test[1]
}

这意味着对于 $tests 的每一行(每一行都被 $_ 实体化，一个对 '#' 进行拆分(这会产生一个用于 Write-Host 语句的数组)

Meaning that for each line of $tests (each line being materialized by $_, one does a split on '#' (which produces an array used in the Write-Host statements)
