Question

I use this:

   public class ConstructionRepository
    {
        private CRDataContext db = new CRDataContext();

        public IQueryable<Material> FindAllMaterials()
        {
            //return db.Materials;
            var materials = from m in db.Materials
                            join Mt in db.MeasurementTypes on m.MeasurementTypeId equals Mt.Id
                            select new Material
                            {
                                Mat_Name =  m.Mat_Name,
                                MeasurementTypeId =  Mt.Name, 
                                 Mat_Type = m.Mat_Type };
            return materials.AsQueryable();
        }
    }

It gives me the only error

1. ‘CrMVC.Models.Material’ does not contain a definition for ‘MatId’,’MesName’,’MesType’

EDIT:
‘MatId’,’MesName’,’MesType’ are just fake names i gave is that wrong..

Answer 1

The Material class must have settable properties with the same names as those used in your select new Material { … } clause, you can’t just make these up.
