**OrganizationRespository.CS**

```c#
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace OCDSandbox.Models
{

    public class OrganizationRepository : IRepository
    {
        private GMS_Sandbox_testDataContext _dataContext;

        public OrganizationRepository()
        {
            _dataContext = new GMS_Sandbox_testDataContext();
        }

        public IList<Organization> ListAll()
        {
            var organizations = from o in _dataContext.Organizations
                select o;
            return organizations.ToList();
        }

        public ICollection<Organization> FindAll()
        {
            return _dataContext.Organizations.ToList();
        }

        public ICollection<Organization> FindByOrgNbr(string OrgNbr)
        {
            var organizations = _dataContext.Organizations.Where(p => p.org_nbr == OrgNbr).ToList();
            return organizations;
        }

    }
}

```

**IRepository.CS**

```c#
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace OCDSandbox.Models
{
    public interface IRepository
    {
        // organization interface
        IList<Organization> ListAll();
        ICollection<Organization> FindAll(); //returns list read only
        ICollection<Organization> FindByOrgNbr();

    }
}

```

Any help is greatly appreciated. This is my first time using repo and I would like to then test FindByOrgNbr in controller. Thanks in advance!
