存储过程与实体框架6代码第一

Question

我有一个Asp Mvc5应用程序与实体框架6，我使用的代码第一种方法。我的模型定义如下：

public class EntityBase 
{ 
[Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)] 
    public int Id {get; set; } 
} 
    public class Question : EntityBase 
    { 

     public QuestionTypeEnum QuestionType {get; set; } 
    } 

    public enum QuestionTypeEnum 
    { 
    none = 0, 
    Type1 = 1, 
    Type2 = 2 
    . 
    . 
    } 
    public class Answer : EntityBase 
    { 
     public Question Answers {get; set; } 
     public userInfo userInfo {get; set; } 
     public bool Isvalidated {get; set;} 
     public FilterTypeEnum FitlterType 
    } 

public enum FilterTypeEnum 
    { 
    filter1 = 0, 
    filter2 = 1 
    } 

    public class UserInfo : EntityBase 
    { 
     public UserInfoTypeEnum UserInfoType {get; set; } 
    } 

    public enum UserInfoTypeEnum 
     { 
      type1 = 0, 
      type2 = 1, 
      type3 = 2 
     } 
    public class Company : EntityBase 
    { 
     public List<Answer> Answers {get; set; } 
     public userInfo userInfoAdmin {get; set; } 
    } 

我有索姆perfermance的问题，我想下面的方法转换成激起过程：

public List<Answer> FilterCompanyAnswers(FilterTypeEnum filter, List<Answer> companyAnswers) 
     { 
      var answers = companyAnswers.Where(a => ((a.Question.QuestionType != QuestionType.none && 
                a.UserInfo != null) && 
                (((a.UserInfo.UserGroup == UserGroupEnum.type1 || 
                (a.UserInfo.UserGroup == UserGroupEnum.type2 && a.IsValidated)) && 
                a.AnswerTypeId == (int)filter && 
                filter == AnswerTypeEnum.filter1) || 
               ((a.UserInfo.UserGroup == UserGroupEnum.type3 || 
                a.UserInfo.UserGroup == UserGroupEnum.type1 || 
                a.UserInfo.UserGroup == UserGroupEnum.type2) && 
                a.FilterTypeEnum == (int)filter && 
               filter == AnswerTypeEnum.filter2))) || 
               (a.Question.QuestionType == QuestionTypeEnum.none)) 
               .OrderByDescending(a => a.DateCreate) 
            .GroupBy(a => a.QuestionId) 
            .Select(grp => grp.First()) 
            .ToList(); 
      return answers; 
     } 

我怎样才能做到这一点？ 在此先感谢

您可以创建您的存储过程并使用db.Database.SqlQuery调用它。 db.Database.SqlQuery('exec myStoredProcedure').ToList<MatchingType>()

结果集必须可转换为MatchingType。
