Domain Service,RIA Services使用的几个注意问题

1.在RIA Services自动生成代码时,自定义方法.

给方法加上PreserveName

[Query(PreserveName=true)]
public IQueryable<Personal> GetPersonalByPersonalId(Guid personalId)

2.生成的代码是不能重载的,需要使用不同的方法名,如:

public IQueryable<Personal> GetPersonals()

与

public IQueryable<Personal> GetPersonalsById(int id)

3.RIA Service中的几个方法关键字

 Insert
o “Insert”, “Add”, “Create” prefixes
o Method signature : void InsertX(T entity), where T is an entity Type

 Update
o “Update”, “Change”, “Modify” prefixes
o Method signature : void UpdateX(T current, T original), where T is an entity Type

 Delete
o “Delete”, “Remove” prefixes
o Method signature : void DeleteX(T entity), where T is an entity Type

 Query
o “Get”, “Fetch”, “Find”, “Query”, “Retrieve”, “Select” prefixes
o Method signature returning IEnumerable<T> or IQueryable<T> where T is an entity Type, and taking zero or more parameters

 Resolve
o “Resolve” prefix
o Method signature : bool ResolveX(T curr, T original, T store, bool isDelete) where T is an entity type
