entity framework custom data type mapping

Question

Given this code:

public class Car 
{
    public virtual int CarId { get; set; }
    public virtual string TypeName { get; set; }
    public ConvertableNullab         


        

Answer 1

The only solution is using something like this:

public class Car 
{
    public virtual int CarId { get; set; }
    public virtual string TypeName { get; set; }
    // This must be accessible to the mapping 
    public double? PriceData { get; set; } 

    public ConvertableNullable Price 
    { 
        get { // Return data from PriceData }
        set { // Set data to PriceData }
    }
}

Your mapping will be:

modelBuilder.Entity().HasKey(x=>x.CarId);
modelBuilder.Entity().Property(x => x.TypeName);
modelBuilder.Entity().Property(x => x.PriceData).HasColumnName("Price");
modelBuilder.Entity().Ignore(x => x.Price);

The problem is that EF globally doesn't have support for custom scalar types.
