问题描述
我很惊讶没有其他人似乎问过这个问题，但是因为ObjectContext.DeleteObject方法只是在调用SaveChanges之前将对象标记为删除，所以可以在提交到DB之前取消标记以进行删除。
I am surprised no-one else seems to have asked this question, but since the ObjectContext.DeleteObject method only marks the object for deletion until SaveChanges is called, is it possible to un-mark it for deletion before commiting to the DB.
推荐答案
遗憾的是不行 - State属性是只读的，SetModified（）无法在Deleted上调用对象。您可以尝试拆卸和附加物体 - 但它不会恢复关系。
That unfortunately won't work - State property is read-only and SetModified() cannot be called on Deleted objects. You can try detaching and attaching the object - but it won't resurrect the relationships.
