C# mongodb serialize an object with a generic property -

i have class 1 property of generic type,

public class factorrecord<t> {     public string id { get; set; }     public string factorname { get; set; }     public t factorvalue { get; set; }     public datetime datetimestamp { get; set; } } 

from question mongodb serialize generic types (classes), know how serialize generic object, not sure how serialize in case in 1 property of generic type.
