我有需要在数据库中创建一堆记录并在出现任何问题时回滚所有记录的过程。我想做的是:
Public Structure Result
Public Success as Boolean
Public Message as String
End Structure
Private _Repository as IEntityRepository
Public Function SaveOrganization( _
ByVal organization As rv_o_Organization) As Result
Dim result = Result.Empty
_Repository.Connection.Open()
_Repository.Transaction = _Repository.Connection.BeginTransaction()
''//Performs validation then saves it to the database
''// using the current transaction
result = SaveMasterOrganization(organization.MasterOrganization)
If (Not result.Success) Then
GoTo somethingBadHappenedButNotAnException
End If
''//Performs validation then saves it to the database
''//using the current transaction
result = SaveOrganziation(dbOrg, organization)
If (Not result.Success) Then GoTo somethingBadHappenedButNotAnException
somethingBadHappenedButNotAnException:
_Repository.Transaction.Commit()
_Repository.Connection.Close()
Return result
End Sub
这是对 GoTo 语句的正确使用,还是只是非常糟糕的设计?有没有更优雅的解决方案?希望这个样本能够理解这一点
