DataContext 的异常

Exceptions by DataContext(DataContext 的异常)

问题描述

我一直在互联网上进行搜索，但似乎找不到 awnser.DataContext 可以抛出哪些异常?或者更具体地说，DataContext.SubmitChanges() 方法抛出哪些异常?

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?

编辑
作为参考，这里列出了 L2S DataContext 可能抛出的可能的已知异常:

EDIT
For reference, here a List of possible known exceptions that could be thrown by the L2S DataContext:

• SqlException
• ChangeConflictException
• DuplicateKeyException
• ForeignKeyReferenceAlreadyHasValueException
• OutOfMemoryException(未正确处理 DataContext 时)

推荐答案

你说得对，MSDN 在这方面帮不上大忙.这是我能从头顶上记住的:

You're right, MSDN is not a great help here. This is what I can remember from the top of my head:

• SqlException(来自 ADO.NET 层)
• ChangeConflictException (L2S)
• DuplicateKeyException (L2S)
• 任何自定义覆盖(部分无效 OnXXXEntity)都可能引发
