How I can Create Calculated Field iIn Entityframwork With A Class

Question

I have below class and I want to know is there any way to calculate TotalBalance field Automatically with Entityframework?

public class Class_Dept_Cred_Balance_Customer
{
    public long LngCustomerID { get; set; }
    public Double TotalDebt { get; set; }
    public Double TotalCred { get; set; }
    public Double TotalBalance { get; set; }
}

It is better to ask this: Is there a way for me to explain to the framework within the above class that field TotalBalance is a computational field and that the program automatically calculates the result wherever this class is used?

TotalBalance  = (TotalDebt  - TotalCred)
