EROR the property or indexer cannot be used in this context because the set accessor is inaccessible
<p>I have the following code: </p>

<pre><code>using System;
using System.Collections.Generic;
using System.Text;
using ProjectBase.Utils;

namespace EnterpriseSample.Core.Domain
{
    public class Notifikasi : DomainObject&lt;string&gt;, IHasAssignedId&lt;string&gt;
    {
        public string Name { get; set; }
        public string Description { get; set; }
        public DateTime StartDate { get; set; }
        public DateTime EndDate { get; set; }
        public DateTime CreatedDate { get; set; }
        public string CreatedBy { get; set; }
        public DateTime UpdateDate { get; set; }
        public string UpdateBy { get; set; }

        public void SetAssignedIdTo(string assignedId)
        {
            Check.Require(!string.IsNullOrEmpty(assignedId), "assignedId may not be null or empty");

            // As an alternative to Check.Require, which throws an exception, the 
            // Validation Application Block could be used to validate the following
            Check.Require(assignedId.Trim().Length == 5, "assignedId must be exactly 5 characters");

            ID = assignedId.Trim().ToUpper();
        }

        public override int GetHashCode()
        {
            return (GetType().FullName + "|" +
                    ID + "|" +
                    Name).GetHashCode();

        }
    }
}

<p>I use the Notifikasi Class in a different class, but <code>oNoti.ID = "12";</code> generates an error:</p>

<blockquote>
  <p>The property or indexer cannot be used in this context because the set
  accessor is inaccessible.</p>
</blockquote>

<p>Can anybody help me solve this? (I use an ORM if that's relevant).</p>

<pre><code>INotifikasiDao dao = DaoFactory.GetNotifikasiDao();

dao.closeSession();
dao.openSession();
EnterpriseSample.Core.Domain.Notifikasi oNoti = new EnterpriseSample.Core.Domain.Notifikasi();
int no = 1;
oNoti.Name = "ETL Account History";
DateTime startDate = DateTime.Today;
DateTime expiryDate = startDate.AddDays(30);
oNoti.StartDate = startDate;
oNoti.EndDate = expiryDate;
oNoti.Description = "ACC_HIST" + startDate + "Failure";
oNoti.ID = "12"; //this is where the error happens

dao.Update(oNoti);
</code></pre>
