How to Clone a Hash and Exclude Specific Fields?

Asked By CuriousCoder42 On

I'm working with a REST API that returns an object's properties as a hash, and I need to update it after modifying one of the fields. However, there are a few fields, like LastModified, that I want to exclude from the re-submit. Initially, I thought I could use a foreach loop similar to what I would do with an array, but I'm unsure how to implement this for a hash. I recently discovered that my actual REST API object is structured as an array with named NoteProperties, so I need a solution that works for that setup instead. Any suggestions?

It's great that you've figured out a working solution! For others with a similar issue, just to clarify, if you're working with a hash, the correct approach would be:

foreach( $entry in $original.Keys ) {
if( $keysToExclude -notcontains $entry ) {
$updated[$entry] = $original[$entry]
}
}

This code effectively skips over the keys you wish to exclude and maintains the rest. Happy coding!

I see where you're coming from! Since you're actually dealing with an array, you can filter it using:

$updated = $original | Where-Object { $_ -notin $valuesToExclude }

This will give you an array without the excluded values. Just make sure the structure matches your API output so that you get the right results!

If your hashtable is stored in a variable called `$original` and the keys you want to exclude are in `$keysToExclude`, you can simply use a loop to remove them like this:

foreach ($key in $keysToExclude) {
$original.Remove($key)
}

If you prefer to keep the original hash intact, clone it first with `$updated = $original.Clone()` and then remove the keys from `$updated`. This way, you won't lose any data from the original hash!
