Question

我有一个像

这样的界面

interface IEmpDeptRepository : IEmployeeRepository,IDepartmentRepository
 {
        IEnumerable<EmpDept> GetAll();        
 }

interface IEmployeeRepository
{
        IEnumerable<Employee> GetAll();       
}

interface IDepartmentRepository
{
        IEnumerable<Department> GetAll();        
}

Class EmpDept 是

 class EmpDept 
        {
            public List<Employee> Employees { get; set; }
            public List<Department> Departments { get; set; }    
        }

现在， EmpDeptRepository 类位于

之下

 public class EmpDeptRepository:IEmpDeptRepository
    {
        private List<EmpDept> empDepts = new List<EmpDept>();

        public EmpDeptRepository()
        {

            Add(new EmpDept { Employees = IEmployeeRepository.GetAll(), Departments = IDepartmentRepository.GetAll() });            
        }

        public EmpDept Add(EmpDept empDept)
        {
            if (empDept == null)
            {
                throw new ArgumentNullException("Employee Department");
            }            
            empDepts.Add(empDept);
            return empDept;
        }


        public IEnumerable<EmpDept> GetAll()
        {
            return empDepts;
        }

        IEnumerable<Employee> IEmployeeRepository.GetAll()
        {
            IEmployeeRepository employeeRepository = new EmployeeRepository();
            return employeeRepository.GetAll();
        }

        IEnumerable<Department> IDepartmentRepository.GetAll()
        {
            IDepartmentRepository deptRepository = new DepartmentRepository();
            return deptRepository.GetAll();
        }
    }

我收到以下错误

Error   1   Inconsistent accessibility: parameter type 'Models.EmpDept' is less accessible than method 'Models.EmpDeptRepository.Add(Models.EmpDept)'
Error   2   Inconsistent accessibility: return type 'Models.EmpDept' is less accessible than method 'Models.EmpDeptRepository.Add(Models.EmpDept)'
Error   3   Inconsistent accessibility: return type 'System.Collections.Generic.IEnumerable<Models.EmpDept>' is less accessible than method 'Models.EmpDeptRepository.GetAll()'

错误是什么..请帮助？

Answer 1

公开所有课程：

public class EmpDept

Answer 2

将类EmpDept设为公开，因为当您想使用公共方法访问它时，它也必须是公共的。

我在下面的C＃代码中犯了什么错误？
