Standard Service Interface Sample code

The first step: The interface is fixed

A standard service interface typically contains

1. Add or update a single record: Serviceresult addorupdate (Entity model)
2. Add or update a single record in bulk: Serviceresult addorupdate (ienumerable<entity> soucre)
3. Get a single record: Entity Getsingle (long? id)
4. Get list record:list<entity> GetList (expression<func<entity, bool>> predicate = null)
5. Get Paging Records:pagedlist<entity> getpagedlist (querymodel query, expression<func<entity, bool>> predicate = Null
6. Delete Record: Serviceresult delete (long id);

Example code that has financial records as an example:

 /// <summary>    ///Financial Records/// </summary>     Public InterfaceIbillservice:idynamicservice {/// <summary>        ///Add or update financial records/// </summary>        /// <param name= "entity" ></param>        /// <returns></returns>        voidaddorupdate (Bill entity); /// <summary>        ///Bulk Add or update financial records/// </summary>        /// <param name= "Soucre" ></param>        /// <returns></returns>        voidAddOrUpdate (ienumerable<bill>soucre); /// <summary>        ///get a financial record/// </summary>        /// <param name= "id" >C Financial Record ID</param>        /// <returns></returns>Bill Getsingle (Long?ID); /// <summary>        ///get a list of financial records/// </summary>        /// <param name= "predicate" >Query Criteria</param>        /// <returns></returns>List<bill> GetList (Expression<func<bill,BOOL>> predicate =NULL); /// <summary>        ///get financial records for Paginated Records/// </summary>        /// <param name= "Query" >Query Criteria</param>        /// <param name= "predicate" >Query Criteria</param>        /// <returns></returns>Pagedlist<bill> getpagedlist (querymodel query, Expression<func<bill,BOOL>> predicate =NULL); /// <summary>        ///Delete financial records/// </summary>        /// <param name= "id" ></param>        /// <returns></returns>        voidDelete (Long?ID); }

Step Two: Complete the service interface

   Public classBillservice:servicebase, Ibillservice { Public voidAddOrUpdate (ienumerable<bill>soucre) {            if(Soucre = =NULL)                Throw NewArgumentNullException (nameof (soucre)); foreach(varIteminchsoucre)            {addorupdate (item); }        }         Public voidaddorupdate (Bill entity) {if(Entity. Id >0) {Repository<BillRepository>().            Updatesingle (entity); } Else{Repository<BillRepository>().            Addsingle (entity); }        }         Public voidDelete (Long?ID) {Repository<BillRepository> (). Delete (r=>r.id==ID); }         PublicList<bill> GetList (Expression<func<bill,BOOL>> predicate =NULL) {            Throw Newnotimplementedexception (); }         PublicPagedlist<bill> getpagedlist (querymodel query, Expression<func<bill,BOOL>> predicate =NULL) {            returnRepository<billrepository>().        Readmany (query, predicate); }         PublicBill Getsingle (Long?ID) {returnRepository<billrepository> (). Readsingle (E = E.id = =ID); }    }

Note implementation:

1. Add and update methods are uniformly written together, do not separate with addorupdate
2. GetList method passed in Expression<func<bill, bool>> parameter
3. The AddOrUpdate method does not need to be assigned a value, and defaults to the entity's default value
