推荐答案

try catch是检查这些内容的最佳方法。

A good question, however, it looks like you will have to perform a manual check.

Note: SubmitChanges() starts a transaction and will roll back if an exception occurs while SubmitChanges is executing.
This does not, however, roll back the changes in memory or tracked by the DataContext; those changes will need to be rolled back manually.
