I'm attempting to obtain a specific range of Offenses and the API documentation calls for setting a header like range="items=0-49". However, when using invoke-resetmethod within PowerShell I receive the following error:

Invoke-RestMethod : The 'Range' header must be modified using the appropriate property or method.
Parameter name: name


Example Code:

Invoke-RestMethod -Method get -Uri $global:OffensesURI -Header @{SEC= $apiKey; Range="items=0-49"}

Anyone happen to know how to resolve this?

Here's the solution, apparently the previous approach didn't work due to a bug in PowerShell:

$request = [System.Net.WebRequest]::Create($global:OffenseURI)
$request.Method = "GET"
$request.Headers.Add("SEC", $apiKey)
# add range header
$request.AddRange("items", 0, $count)

$reader = New-Object System.IO.StreamReader($request.GetResponse().GetResponseStream())
$data = ConvertFrom-Json $reader.ReadToEnd()
