In one of my recent projects I needed a generic service as a facade to handle General activities such as CRUD.Therefor I searched as Many as I could but there was no Idea on generic services so I tried to figure it out by my self.Finally,I found a way :Create a generic contract as below :[ServiceContract]
public interface IEntityReadService<TEntity>
where TEntity : EntityBase, new()
{
[OperationContract(Name = "Get")]
TEntity Get(Int64 Id);
[OperationContract(Name = "GetAll")]
List<TEntity> GetAll();
[OperationContract(Name = "GetAllPaged")]
List<TEntity> GetAll(int pageSize, int currentPageIndex, ref int totalRecords);
List<TEntity> GetAll(string whereClause, string orderBy, int pageSize, int currentPageIndex, ref int totalRecords);
}then create your service class : public class GenericService<TEntity> :IEntityReadService<TEntity>
where TEntity : EntityBase, new()
{#region Implementation of IEntityReadService<TEntity>
public TEntity Get(long Id)
{
return BusinessController.Get(Id);
}
public List<TEntity> GetAll()
{
try
{
return BusinessController.GetAll().ToList();
}
catch (Exception ex)
{
throw;
}
}
public List<TEntity> GetAll(int pageSize, int currentPageIndex, ref int totalRecords)
{
return
BusinessController.GetAll(pageSize, currentPageIndex, ref totalRecords).ToList();
}
public List<TEntity> GetAll(string whereClause, string orderBy, int pageSize, int currentPageIndex, ref int totalRecords)
{
return
BusinessController.GetAll(pageSize, currentPageIndex, ref totalRecords, whereClause, orderBy).ToList();
}
#endregion}
Then, set your EndPoint configuration in this way :<endpoint
address="myAddress" binding="basicHttpBinding"
bindingConfiguration="myBindingConfiguration1"
contract="Contracts.IEntityReadService`1[[Entities.mySampleEntity, Entities]], Service.Contracts" />
