在Entity Framework repository下加两个方法：
public virtual T GetByEntityName(object id, string EntityTypeName)
{
dynamic repository = GetEFRepository(EntityTypeName);
if (repository != null)
return repository.Entities.Find(id);
else
return null;
}
public virtual dynamic GetRecordRepository(string EntityTypeName)
{
dynamic repository = GetEFRepository(EntityTypeName);
if (repository != null)
{
var type = repository.GetType().GetGenericArguments()[0];
dynamic part = Activator.CreateInstance(type);
return part;
}
else
{
return null;
}
}
private object GetEFRepository(string EntityTypeName)
{
if (_repositoryDictionary == null)
{
var typesToRegister = TypeUtil.GetEntityTypes();
_repositoryDictionary = new Dictionary<string, object>();
foreach (var type in typesToRegister)
{
object repository = Activator.CreateInstance(typeof(EfRepository<>).MakeGenericType(type), _context);
_repositoryDictionary[type.Name] = repository;
}
}
if (_repositoryDictionary.ContainsKey(EntityTypeName))
return _repositoryDictionary[EntityTypeName];
else
return null;
}
TypeUtil.cs
public class TypeUtil { public static IList<Type> GetEntityTypes() { var cacheManager = new MemoryCacheManager(); return cacheManager.Get("ENTITY-TYPE-ASSEMBLY", () => { var typesToRegister = Assembly.GetExecutingAssembly().GetTypes() .Where(type => (typeof(BaseEntity).IsAssignableFrom(type) && (type.GetConstructor(Type.EmptyTypes) != null))); return typesToRegister.ToList(); }); } }
test:
[Test] public void TypeUtilTest() { var n = _repository.GetRecordRepository("NewsEntity"); dynamic nm = _repository.GetByEntityName(1, "NewsEntity"); var title = nm.Title; var c = _repository.GetRecordRepository("NewsCommentEntity"); dynamic cm = _repository.GetByEntityName(1, "NewsCommentEntity"); var comment = cm.Comment; string pass = title + "\n" + comment; Assert.Pass(pass); }
ef 多个模块，通过程序集映射entity，指定对应的repository
