Powershell trouble getting value from key named count

I have a simple json that I am trying to get values from in Powershell

$webData = @'
{
            "results": [
               {
                  "facet": "266976",
                  "appid": "266976",
                  "count": 233206
               },
               {
                  "facet": "27096405",
                  "appid": "27096405",
                  "count": 85669
               }
            ]
}
'@

$data1 = $webData | ConvertFrom-Json 

Write-Output $data1.results.count

When I write output I get values count and not value itself like I do for appid and facet. Desired result: 233206 Current result: 2

I cannot change json. Is there a way for PS not to see it as a count operator? Thank you

As mklement0 notes, in this case the array type's ICollection.Count property takes precedence over member access enumeration of the array-element property named Count.

A simple workaround is to use the intrinsic method .ForEach(string PropertyName):

$data1.results.ForEach('count')

As Santiago Squarzon notes, the type of ForEach() output is Collection`1. If you actually need an array, use the array sub-expression operator @() or use the workaround suggested by Santiago, using GetEnumerator().

$arrayOfCount = @($data1.results.ForEach('count'))
$arrayOfCount = $data1.results.GetEnumerator().Count

Output:

233206
85669

As Santiago Squarzon noted, if you actually want to get the value of count for the first object only, you can write:

$data1.results[0].Count

Output:

233206

Note that Write-Output is effectively redundant, because PowerShell implicitly outputs the "result" of any statement. So I've removed it in the samples above.
