这很糟糕！

随时改变怎么c.Billingddress.Addr影响c.ShippingAddrress.Addr

没有意义！

I have a complex type which is used twice on an entity. For instance customer has billing and shipping address. By default code first, makes all the properties of the complex type as not required so the database columns are marked as nullable. So far so good. Now i want to make billingaddress be required but if the shipping address is not present, its okay.. when i configure BillingAddress properties as required, it also forces the shippingaddress properties as required. below should not affect the shippingaddress and shippingaddress should generate nullable columns.

 

protected override void OnModelCreating(System.Data.Entity.ModelConfiguration.ModelBuilder modelBuilder)

        {

            var cust = modelBuilder.Entity<Customer>();

            cust.Property(c => c.BillingAddress.Addr).HasColumnName("BillingAddr").IsRequired();

            cust.Property(c => c.BillingAddress.City).HasColumnName("BillingCity").IsRequired();

            cust.Property(c => c.BillingAddress.State).HasColumnName("BillingState").IsRequired();

            //EF also maes ShippingAddr,ShippingCity and ShippingState as also required.not good

            cust.Property(c => c.ShippingAddress.Addr).HasColumnName("ShippingAddr");

            cust.Property(c => c.ShippingAddress.City).HasColumnName("ShippingCity");

            cust.Property(c => c.ShippingAddress.State).HasColumnName("ShippingState");

                       

        }

 

Help!
