Get key value from string using Powershell

Question

I am trying to get key value using Regex in powershell.

$string = "key1:value1,key2:value2,key3:value3"
$name = [Regex]::Matches($string, ':([^/]+),') | Select -ExpandProperty Value
Write-Host "Name :" $name

I want output like this :

$key1 = "value1"
$key2 = "value2"
$key3 = "value3"

Output i am getting :

Name : :value1,key2:value2,

Answer 1

If you are using the comma to separate the key:value pairs this should accomplish what you are after.

$string = "key1:value1,key2:value2,key3:value3"
$ht = @{} # declare empty hashtable
$string -split ',' | % { $s = $_ -split ':'; $ht += @{$s[0] =  $s[1]}} 
# split the string by ',', then split each new string on ':' and map them to the hashtable

Outputs the following (note by default they are not ordered)

PS C:\> $ht

Name                           Value
----                           -----
key3                           value3
key1                           value1
key2                           value2

Answer 2

Pretty sure that sysg0blin's helpful answer can do the job, but if you really want to set specific variables this can be done with such script:

$string = "key1:value1,key2:value2,key3:value3"
$splitted = $string -split ','
$splitted | ForEach-Object {
  $i = $_ -split ":"
  Set-Variable -Name $i[0] -Value $i[1]
}

What you do here is to split string into array of key:value pair and then split each pair into array with 2 elements, first being variable name and second being value of the variable.
