Serializing DbCommand with Newtonsoft.Json

I am trying to serialize Entity Framework DbCommand to json with Newtonsoft.Json:

public void NonQueryExecuted(DbCommand command, DbCommandInterceptionContext<int> interceptionContext) {
   var path = "C:/result.json";
   File.WriteAllText(path, JsonConvert.SerializeObject(command));
}

However, in result json file the parameters are ToString() values rather than objects:

"Parameters": ["@0", "@1", "@2"]

How do I tell the serializer to serialize the whole objects?
