Powershell Import-CSV issue

Dashrender

I'm not a scriptor, but to me it looks like you are adding that stuff to your value

    $string1 = "(gPLink=*" + $guid + "*)"

what if you just use

   $string1 = "*"

I am trying to import a CSV file with powershell, iterate through it and run a command on each entry.
$importcsv = import-csv "filename"
foreach($guid in $importcsv)
    {
    $string1 = "(gPLink=*" + $guid + "*)"
    echo $string1
    }
I'm able to do the first two things. However the third isn't working as expected. When I interate through it just by echoing the variable I get what I am expecting.
31346975-2114-40b6-a423-8cbc9adc76fd
However when I run it through $string1 I get the following
(gPLink=*@{guid=31346975-2114-40b6-a423-8cbc9adc76fd}*)
For some reason it adds @{guid= and then a } to the string.

Anyone have any ideas how I can remove those extra characters?

Try

$importcsv = import-csv "filename"
foreach($guid in $importcsv) 
   { 
   $string1 = "(gPLink=*" + $guid + "*)"``
   $noondles = $string1.Trim("@","{guid=","}")
   echo $noodles
  }

If you look in the csv file before the import, are the @{guid= and } in there?
If so, how are you obtaining and exporting the GUIDs?

I'm no expert, but I reckon it is treating $guid as an array when you use "$string1 =", so the output is displaying as an array value, hence the @{ and } characters.

I just get a "*"

No, the CSV file doesn't contain the @(guid=...}. The header of the column is guid and that changes when I name the header something else.

So it looks like when pulling it through string concatenation (which is what the + signs are doing) it pulls in both the header and the value. I just need the value.

I've tried to call out the first element in the array and it gives me an invalid operation and cannontIndex error. Which from searching seems to indicate it isn't an array.

When I do

$guid.gettype()

It returns this

IsPublic IsSerial Name                                     BaseType                                                         
-------- -------- ----                                     --------                                                         
True     False    PSCustomObject                           System.Object

Did you try the trim() thing?

Yes,

It gives me the following error

Cannot convert argument "1", with value: "{guid=", for "Trim" to type "System.Char": "Cannot convert value "{guid=" to type "System.Char". Error: "String must be exactly one character long.""

I'm guessing that is because it isn't a string?

Instead of import-csv could you use Get-Content

ie
$importcsv = Get-Content "filename"
foreach($guid in $importcsv)
{
$string1 = "(gPLink=" + $guid + ")"
echo $string1
}

I've tested this and it works, assuming you only have one column in your CSV file.

Perfect that does work. Thank you.

I found an even easier way.

$guid.id

Since the $guid is a Powershell custom object you can call individual elements of it. This is the first time I've really dug into Powershell but this is a good thing to know.
