Question

I have a LINQ to object query to select all the persons that are above 20 years old

IEnumerable<Object> result = null;
result = (from person in AllPersons.ToList()
          where  person.age > 20
                  select new
                  {
                      FirstName= person.FirstName,
                      LastName= person.LastName,
                      Email= person.Email,
                      PhoneNumber= person.PhoneNumber


                  });
return result;

I have a parameter string SortProperty I want to use to sort the result based on the property.

So for example if SortProperty="FirstName" I want to sort the result based on the first name.

I tried to do the following:

return result.OrderBy(x => x.GetType().GetProperty(SortProperty));

but it did not work

any idea how to do it?

PS: I don’t want to test all the possibilities, and do a if-else on each, or a case switch. I’m looking for an efficient way to do this

Thanks

Try

return result.OrderBy(x => x.GetType().GetProperty(SortProperty).GetValue(x, null));
