Question

I have a LINQ query in function, like below code:

public object RetrieveFday(DateTime _dt)
    {
 var fp = from f in RSC.tbl_FoodPlan join food in RSC.tbl_Food
                              on f.FoodID equals food.FoodID
                              where f.Day == _dt
                              select new 
                              {
                                 FoodName= food.Name,
                                 Fholiday= f.HoliDay
                              };


            return fp;
   }

now I call this function in other place, I want to get result and separate them to display every one in different label, when call the function and get result I cant read property of them:

var test = RetrieveFday(dt);

how can read the property in result that into test?

Answer 1

Anonymous types are not meant to use as a return types, so just create a new class to hold your projection data:

public class FoodNameAndHoliday
{
    public string FoodName { get; set; }
    public string Fholiday { get; set; }
}

And modify your RetrieveFday function to use your class in the select:

public IEnumerable<FoodNameAndHoliday> RetrieveFday(DateTime _dt)
{
     var fp = from f in RSC.tbl_FoodPlan join food in RSC.tbl_Food
                          on f.FoodID equals food.FoodID
                          where f.Day == _dt
                          select new FoodNameAndHoliday
                          {
                             FoodName= food.Name,
                             Fholiday= f.HoliDay
                          };
      return fp;
}

And you can then use your function like:

var test = RetrieveFday(dt);
foreach(var item in test)
{
    DoSomethingWith(item.FoodName);
    DoSomethingWith(item.Fholiday);
}
