"The modifier 'readonly' is not valid for this item"

[shamira]

I need help with this error :"The modifier 'readonly' is not valid for this item"

I am writing this code in projrct type class Library
Here is the code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;


namespace BE
{
    public enum STATUSACCOUNT { Bounded, Active, OnProbation };
    public class Account
    {
        public int AccountNumber { get; set; }
        public int AccountBranchNumber { get; set; }
        public readonly DateTime DateOpeingAccount { get; set; } //error
        public STATUSACCOUNT StatusAccount { get; set; }
        public string Password { get; set; }
        public int Balance { get; set; }
        public int CreditFacility { get; set; }
        public DateTime CreditFacilityExpiration { get; set; }
        public string TypeAccount { get; set; }
    }
}

Thank you very much.

I would think you're getting that error because you have a getter & setter but have marked it as read only, which just cannot work. Try changing it to this:

 
public DateTime DateOpeingAccount { get; private set; }
