示例1: AssignStubx
internal static void AssignStubx(object poco, DbContext db)
{
IEnumerable<PropertyMapping> piNeedStub = Mapper.StubsNeeded(poco.GetType());
foreach (PropertyMapping pm in piNeedStub)
{
// pm.PropertyPoco.First(). e.g. Customer of Customer.CustomerId. Customer is PropertyPoco[0], CustomerId is PropertyPoco[1]
PropertyInfo pocoForeign = poco.GetType().GetProperty(pm.PropertyPoco[0], BindingFlags.Public | BindingFlags.Instance);
if (pocoForeign == null) continue;
object val = pocoForeign.GetValue(poco, null);
if (val != null)
{
PropertyInfo pocoForeignId = pocoForeign.PropertyType.GetProperty(pm.PropertyPoco.Last(), BindingFlags.Public | BindingFlags.Instance);
object id = pocoForeignId.GetValue(val, null);
pocoForeign.SetValue(poco, LoadStub(pocoForeign.PropertyType, pm.PropertyPoco.Last(), id, db), null);
}
else
{
// foreign key is null'd
// nullable foreign key association
