在这一行

public class ApplicantRepository : IApplicantRepository, IDi

sposable { 私人实体背景;

    public ApplicantRepository(Entities context)
    {
        this.context = context;
    }

    public IEnumerable<APPLICANT> GetApplicant()
    {
        return context.APPLICANTs.ToList(); <--------- Where i Triggered the Error
    }

    public APPLICANT GetApplicantByID(int id)
    {
        return context.APPLICANTs.Find(id);
    }
