我得到的错误是

错误1'OCDSandbox.Models.OrganizationRepository'未实现接口成员 'OCDSandbox.Models.IRepository.FindByOrgNbr（）'C：\ source temp \ OCDSandbox \ OCDSandbox \ Models \ OrganizationRepository.cs第9行

OrganizationRespository.CS

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

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();

    }
}

非常感谢任何帮助。这是我第一次使用repo，然后我想在控制器中测试FindByOrgNbr。提前谢谢！

Answer 1

您在FindByOrgNbr

的定义中缺少接口中的参数

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

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

    }
}

Answer 2

谢谢，因为界面有以下方法：ICollection<Organization> FindByOrgNbr();，您的班级有public ICollection<Organization> FindByOrgNbr(string OrgNbr)

界面似乎也需要OrgNbr参数。

Answer 3

您在OrgNbr的接口定义中缺少FindByOrgNbr()参数。

public interface IRepository
{
    // organization interface
    IList<Organization> ListAll();
    ICollection<Organization> FindAll(); //returns list read only
    ICollection<Organization> FindByOrgNbr(string OrgNbr);
}

存储库未正确实现接口
