minddless passenger有一个项目，允许使用实体框架从存储过程中返回多个结果集。下面是他的一个例子....

using (testentities te = new testentities())
{
    //-------------------------------------------------------------
    // Simple stored proc
    //-------------------------------------------------------------
    var parms1 = new testone() { inparm = "abcd" };
    var results1 = te.CallStoredProc<testone>(te.testoneproc, parms1);
    var r1 = results1.ToList<TestOneResultSet>();
}

对我来说，这是通过在传递参数时从存储过程中拉回数据来实现的。

var param = new SqlParameter("@datetime", combinedTime);
var result = 
        _db.Database.SqlQuery<QAList>("dbo.GetQAListByDateTime @datetime", param).ToList();

_db是dbContext

当EDMX创建时，如果你在表选择选项中选择存储过程，那么只需使用过程名调用存储过程…

var num1 = 1; 
var num2 = 2; 

var result = context.proc_name(num1,num2).tolist();// list or single you get here.. using same thing you can call insert,update or delete procedured.

在MYsql中创建Procedure。

delimiter //
create procedure SP_Dasboarddata(fromdate date, todate date)
begin
select count(Id) as count,date,status,sum(amount) as amount from 
details
where (Emidate between fromdate and todate)
group by date ,status;
END;
//

创建包含存储过程返回结果集值的类

[Table("SP_reslutclass")]
public  class SP_reslutclass
{
    [Key]
    public int emicount { get; set; }
    public DateTime Emidate { get; set; }
    public int ? Emistatus { get; set; }
    public int emiamount { get; set; }

}

在Dbcontext中添加Class

  public  class ABCDbContext:DbContext
{
    public ABCDbContext(DbContextOptions<ABCDbContext> options)
       : base(options)
    {

    }

 public DbSet<SP_reslutclass> SP_reslutclass { get; set; }
}

在存储库中调用实体

   var counts = _Dbcontext.SP_reslutclass.FromSql("call SP_Dasboarddata 
                    ('2019-12-03','2019-12-31')").ToList();

用你的例子，这里有两种方法来实现这一点:

方法#1:使用存储过程映射

请注意，这段代码可以使用映射，也可以不使用映射。如果在实体上关闭映射，EF将生成一个插入+选择语句。

protected void btnSave_Click(object sender, EventArgs e)
{
     using (var db = DepartmentContext() )
     {
        var department = new Department();
        
        department.Name = txtDepartment.text.trim();
        
        db.Departments.add(department);
        db.SaveChanges();
        
        // EF will populate department.DepartmentId
        int departmentID = department.DepartmentId;
     }
}

方法#2:直接调用存储过程

protected void btnSave_Click(object sender, EventArgs e)
{
     using (var db = DepartmentContext() )
     {
        var name = new SqlParameter("@name", txtDepartment.text.trim());
        
        //to get this to work, you will need to change your select inside dbo.insert_department to include name in the resultset
        var department = db.Database.SqlQuery<Department>("dbo.insert_department @name", name).SingleOrDefault();

       //alternately, you can invoke SqlQuery on the DbSet itself:
       //var department = db.Departments.SqlQuery("dbo.insert_department @name", name).SingleOrDefault();
        
        int departmentID = department.DepartmentId;
     }
}

我建议使用第一种方法，因为您可以直接使用department对象，而不必创建一堆SqlParameter对象。

它为我工作在代码第一。它返回一个匹配视图模型属性的列表(StudentChapterCompletionViewModel)

var studentIdParameter = new SqlParameter
{
     ParameterName = "studentId",
     Direction = ParameterDirection.Input,
     SqlDbType = SqlDbType.BigInt,
     Value = studentId
 };

 var results = Context.Database.SqlQuery<StudentChapterCompletionViewModel>(
                "exec dbo.sp_StudentComplettion @studentId",
                 studentIdParameter
                ).ToList();

已更新

Context是继承DbContext类的实例，如下所示。

public class ApplicationDbContext : DbContext
{
    public DbSet<City> City { get; set; }
}

var Context = new  ApplicationDbContext();
