Try
db.SubmitChanges(ConflictMode.ContinueOnConflict)
Catch ex As ChangeConflictException

Next
End Try示例3:
Try
db.SubmitChanges(ConflictMode.ContinueOnConflict)
Catch ex As ChangeConflictException
Console.WriteLine(ex.Message)
For Each occ As ObjectChangeConflict In db.ChangeConflicts
' Automerge database values into current for members
' that client has not modified.

' Submit succeeds on second try.
db.SubmitChanges(ConflictMode.FailOnFirstConflict)
