I'm struggling to dynamically expose a list of values containing Name, Database Column Name and value of an entity containing owned types.
public class Foo {
public int Id { get; set; }
public Certificate Certificate { get; set; }
}
[Owned]
public class Certificate {
public string Number { get; set; }
// Some logic here
}
public class PropBinding()
{
public string Name{ get; set; }
public string ColName{ get; set; }
public string Content{ get; set; }
}
Owning relationship declared in model builder
modelBuilder.Entity<Foo>(entity =>
entity.OwnsOne(e => e.Certificate)
.UsePropertyAccessMode(PropertyAccessMode.Property)
With other declarations like column name. This information is stored in a single table, this reduced example with an int Id and a string Number.
Using Reflexion, I can get the values of Foo properties. Then I identify owned types and then call my function again to have the bindings off owned types properties, but it fails.
foreach(var propBinding in GetBindings(myFoo, myFoo.GetType())
{
// no problem
}
var owned = contentType.GetNavigations().FirstOrDefault(x => x.ForeignKey.IsOwnership);
foreach(var propBinding in GetBindings(myFoo, owned.ClrType())
{
// success for name and colname
// fails to get the value due to wrong type exception
}
public class IEnumerable<PropBinding> GetBindings(T entity, System.Type typeO) // Simplified for the sake of clarity
{
var contentType = _db.Model.FindEntityType(entity.GetType());
var storeObjectIdentifier = StoreObjectIdentifier.Table(contentType.GetTableName(), contentType.GetSchema());
var props = typeO.GetProperties().Where(x => x.PropertyType.BaseType != null).ToList();
foreach(var prop in props)
{
yield return new PropBinding() {
Name = prop.Name,
ColName = contentType.FindProperty(p.Name)?.GetColumnName(storeObjectIdentifier),
Content = prop.GetValue(entity, null)
}
}
}
Thank you
