如何使用Powershell从.Csv文件中获取一行信息? [英] How to get one row of info from .Csv file with Powershell?

问题描述

powershell脚本:

$test = import-csv "C:\CSVFiles\test.csv"
ForEach ($item in $test)
{
$Name = $item.("Name") 
$property = $item.("property")
$location = $item.("location")

Write-Output "$Name=$Name"
Write-Output "Property=$property"
Write-Output "Location=$location"
}

此脚本显示每一行的名称，属性和位置的所有数据.我希望结果只显示一行的数据；例如，行:n1; 13; computer

This script shows all the data for name,property and location for each row. I want the results to only show the data of one row;for example the row: n1;13;computer

Cvs文件=

Name;property;location
n1;13;computer
n2;65;computer
n3;12;tablet
n4;234;phone
n5;123;phone
n6;125;phone

当前脚本显示的内容:

Name=n1
Property=13
Location=computer
Name=n2
Property=65
Location=computer
Name= n3
Property=12
Location=tablet
Name=n4
Property=234
Location=phone
Name=n5
Property=123
Location=phone
Name=n6
Property=125
Location=phone

推荐答案

有很多方法可以选择csv的行并显示数据

There are many ways to select a Row of a csv and to present the data

为演示起见，我将内联csv与here字符串一起使用.

For demonstration I use an inline csv with a here string.

$Test = @"
Name;property;location
n1;13;computer
n2;65;computer
n3;12;tablet
n4;234;phone
n5;123;phone
n6;125;phone
"@ | ConvertFrom-Csv -delimiter ';'

---

> $test[0]

Name property location
---- -------- --------
n1   13       computer

---

> $test | where-object Name -eq 'n1'

Name property location
---- -------- --------
n1   13       computer

---

> $test | where-object Name -eq 'n1' | Select-Object Name,property

Name property
---- --------
n1   13

---

> $test | where-object Name -eq 'n1' | ForEach-Object {"Name:{0} has property: {1}" -f $_.Name,$_.property}
Name:n1 has property: 13

一旦导入了csv行内容，便会转换为对象

如果要获取与条件匹配的csv的原始行，请不要导入，但:

If you want to get the original row of the csv matching a criteria don't import but:

> Get-Content "C:\CSVFiles\test.csv" | Select-String '^n1'

n1;13;computer

^ n1 是在行首定位模式的正则表达式.

^n1 is a regular expression anchoring the pattern at line begin.

Select-String -Path "C:\CSVFiles\test.csv" -Pattern '^n1'

没有管道就一样
