Generic <T> how cast ?
- by Kris-I
Hi,
I have a "Product" base class, some other classes "ProductBookDetail","ProductDVDDetail" inherit from this class. I use a ProductService class to make operation on these classes. But, I have to do some check depending of the type (ISBN for Book, languages for DVD). I'd like to know the best way to cast "productDetail" value, I receive in SaveOrupdate. I tried GetType() and cast with (ProductBookDetail)productDetail but that's not work.
Thanks,
var productDetail = new ProductDetailBook() { .... };
var service = IoC.Resolve<IProductServiceGeneric<ProductDetailBook>>();
service.SaveOrUpdate(productDetail);
var productDetail = new ProductDetailDVD() { .... };
var service = IoC.Resolve<IProductServiceGeneric<ProductDetailDVD>>();
service.SaveOrUpdate(productDetail);
public class ProductServiceGeneric<T> : IProductServiceGeneric<T>
{
private readonly ISession _session;
private readonly IProductRepoGeneric<T> _repo;
public ProductServiceGeneric()
{
_session = UnitOfWork.CurrentSession;
_repo = IoC.Resolve<IProductRepoGeneric<T>>();
}
public void SaveOrUpdate(T productDetail)
{
using (ITransaction tx = _session.BeginTransaction())
{
//here i'd like ot know the type and access properties depending of the class
_repo.SaveOrUpdate(productDetail);
tx.Commit();
}
}
}
