由DataContext的例外 [英] Exceptions by DataContext
本文介绍了由DataContext的例外的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我一直在做一些在互联网上搜索,但我似乎无法找到awnser。可一个DataContext抛出什么异常?或者更具体的,有什么异常是否DataContext.SubmitChanges()方法抛出?
I've been doing some searching on the internet, but I can't seem to find the awnser. What exceptions can a DataContext throw? Or to be more specific, what exceptions does the DataContext.SubmitChanges() method throw?
修改结果
仅供参考这里一个可能的已知的例外列表,可以由L2S的DataContext抛出:
EDIT
For reference, here a List of possible known exceptions that could be thrown by the L2S DataContext:
- 的SQLException
- ChangeConflictException
- DuplicateKeyException
- ForeignKeyReferenceAlreadyHasValueException
- OutOfMemoryException异常时(没有正确处理DataContext的)
- SqlException
- ChangeConflictException
- DuplicateKeyException
- ForeignKeyReferenceAlreadyHasValueException
- OutOfMemoryException (when not correctly disposing the DataContext)
推荐答案
您说得对,MSDN是不是在这里有很大的帮助。这是我可以从我的头顶记住:
You're right, MSDN is not a great help here. This is what I can remember from the top of my head:
- 的SQLException(从ADO.NET层)
- ChangeConflictException(L2S)
- DuplicateKeyException(L2S)
- 凡是cusomized覆盖(部分无效OnXXXEntity)可能会提高
- SqlException (from the ADO.NET layer)
- ChangeConflictException (L2S)
- DuplicateKeyException (L2S)
- Anything that cusomized overrides (partial void OnXXXEntity) may raise
