How can I use this file as an object in the main program and work with it?

    public class EcmSimpleField
    {

        public string displayName { get; set; }
        public string internalName { get; set; }
        public string dbName { get; set; }
        public bool visible { get; set; }
        public string type { get; set; }
    }

    public class BaseParameter
    {
        public string value { get; set; }
        public string type { get; set; }

    public class SystemField
    {
        public string value { get; set; }
        public string type { get; set; }
    }
