Powershell function-get multple values - powershell

Question

I have file 1.csv
number, name # column name
1,john
2,mike
3,test
4,test2
...
I created function for returning all values from this csv (number,name)
Function Get-CSV {
[CmdletBinding()]
param (
# CSV File path
[Parameter(Mandatory=$true)][string]$path
)
#Create an hashtable variable
[hashtable]$return = #{}
Import-Csv $path |
ForEach-Object {
$number = $_.number
$name = $_.name
$return.name = $name
$return.number = $number
return $return
}
# return $return un-commenting this line don't change output
}
# calling function
$a = Get-CSV "C:\Users\1.csv"
$a.number
$a.name
I get only one (last row from CSV) - a.name = test2 and a.number = 4
How to get all rows from CSV when calling this function ?

Answer 1

You need to construct an array of hashtables for this to work. Even better, I would create an array of objects because it gives you control over the property names. You can change the function definition to:
Function Get-CSV {
[CmdletBinding()]
param (
# CSV File path
[Parameter(Mandatory=$true)][string]$path
)
#Create an empty array variable
$return = #()
Import-Csv $path |
ForEach-Object {
$return += ,(New-Object PSObject -property #{'name'= $_.name; 'number'= $_.number})
}
return $return
}
This gives you:
$a = Get-CSV "C:\Users\1.csv"
$a
name number
---- ------
john 1
mike 2
test 3
test2 4
Note
I'm not sure on your exact use case, but Import-Csv already gives you the information back as an object, so there may not be a need to create a separate one.

After lot of googling and try/errors found solution:
Function Get-CSV {
[CmdletBinding()]
param (
# CSV File path
[Parameter(Mandatory=$true)][string]$path
)
Import-Csv $path |
ForEach-Object {
$number = $_.number
$name = $_.name
[pscustomobject]#{
name = $name
number = $number
}
}
}
