C#: get the value of a key in an object using regex

I have a key with random bits of string in it making it difficult to extract it's value. How would I go about doing it when I don't know the random bits ahead of time?

given: 

sample = {\"total_ra4jhga987y3h_power\": 30}

Is it possible to do something directly like

dynamic obj = JsonConvert.DeserializeObject(sample);
obj[@"^total_(.*)_power$"] ---> should give me 30

Use LINQ to JSON instead. If you parse it as a JObject, you can iterate over all the properties, and find those which match your regex.

Regex regex = new Regex(...);
JObject json = JObject.Parse(text);
foreach (var property in json.Properties())
{
    if (regex.IsMatch(property.Name))
    {
        ...
    }
}
