$json = New-Object Chilkat.JsonObject

$jsonStr = "{ `"id`": 1, `"name`": `"A green door`", `"tags`": [`"home`", 22, `"green`"], `"price`": 125 }"

$success = $json.Load($jsonStr)
if ($success -ne $true) {
    $($json.LastErrorText)
    exit
}

# Get the "tags" array, which contains "home", 22, "green"
$tagsArray = $json.ArrayOf("tags")
if ($json.LastMethodSuccess -eq $false) {
    $("tags member not found.")
    exit
}

# Get the value at each array index. 
# Output will be:
# [0] = home
# [0] as integer = 0
# [1] = 22
# [1] as integer = 22
# [2] = green
# [2] as integer = 0

$arraySize = $tagsArray.Size

for ($i = 0; $i -le $arraySize - 1; $i++) {

    $sValue = $tagsArray.StringAt($i)

    $("[" + $i + "] = " + $sValue)

    $iValue = $tagsArray.IntAt($i)
    $("[" + $i + "] as integer = " + $iValue)

}

# Note: The StringAt method returns the value as a string regardless of the type.

# The IntAt method returns the value as an integer.  If the value does not convert to 
# an integer, then 0 is returned
