Update a numeric property of a JSON object in an array

My JSON config.json:

[
{
"names":"Steam",
"count": 1,
},
{
"names":"game",
"count": 2,
}
]


I need to update count's property in the array in c#.
I tried

count

JObject objectproperty = JObject.Parse(File.ReadAllText(@"config.json"));


but this gives me the error

Newtonsoft.Json.JsonReaderException: "Error reading JObject from JsonReader. Current JsonReader item is not an object: StartArray. Path '', line 1, position 1."


JArray

JObject

You can use a JToken
Assuming that your JSON is:
(notice I had to remove some ,)

,

[
{
"names":"Steam",
"count": 1
},
{
"names":"game",
"count": 2
}
]


You can use this:

var config_file = @"config.json";

var objectproperty = JToken.Parse(File.ReadAllText(config_file));
foreach (var obj in objectproperty)
{
var count = (long)obj["count"];

obj["count"] = count * 3;
}

System.IO.File.WriteAllText(config_file, objectproperty.ToString());
