'How do I restructure this JSON object? [closed]

I want to convert json data from one format to another like below in c#. I want "Region" to be a list.

From:

{
        "Document": {
            "Regions": {
                "Region": {
                    "Color": "#FFFF0000",
                    "Type": "Rectangle",
                }
            }
        }
    }

To:

{
    "Document": {
        "Regions": {
            "Region": [{
                "Color": "#FFFF0000",
                "Type": "Rectangle"
            }]
        }
    }
}
