Entity Framework | Double property that allows null

Question

My property allows values double and values null. In the SQL Server Database it is set to decimal(18, 2).

But when seventh some value (ex: 5.00), makes the mistake below.

Error:

The 'Rating' Property on 'Occurrence' could not be set to a 'System.Decimal' value. You must set this Property to a non-null value of type 'System.Double'.

Model:

public class Ocorrencia
{
    [Key]
    public int id { get; set; }
    public double? Avaliacao { get; set; }
}

How it should stay to function properly?

Answer 1

You can cast for double

ocorrencia.Avaliacao = (double)5.00;

Answer 2

Maybe you’re not forcing the notation to double:

ocorrencia.Avaliacao = 5.00D;
