Convert Anonymous type to IEnumerable<> in EF6

Question

I am developing an MVC application using Entity Framework. I want to get 5 columns from a table and return them in an IEnumerable type. My code for this is:

Answer 1

You need to simply project the Type MST instead of anonymous type:-

n = db.MSTs.Select(x => new MST 
                      { 
                          Id = x.Id, 
                          Code = x.Code,
                          Desc =  x.Desc, 
                          L1= x.L1, 
                          L2 = x.L2 
                       }).OrderBy(h => h.Code);

Provided, you have all these properties in MST. Also, it should not be a mapped entity it should be a DTO.

Also, you don't need ToList here since Select returns IEnumerable.

Update:

Since it is a mapped entity in Entity Framework, one way is to first project the anonymous type and then the Model type like this:-

n = db.MSTs.Select(x => new 
                          { 
                              x.Id, 
                              x.Code,
                              x.Desc, 
                              x.L1, 
                              x.L2 
                           }).OrderBy(h => h.Code)
                           .AsEnumerable()
                           Select(x => new MST 
                                   { 
                                      Id = x.Id, 
                                      Code = x.Code,
                                      Desc =  x.Desc, 
                                      L1= x.L1, 
                                      L2 = x.L2 
                                   });
