如何在LINQtoSQL中撤消ChangeSet

YourDataContext context = new YourDataContext();

YourEntity entity = context.YourEntities.FirstOrDefault(e => e.Id == id);

entity.Property1 = "New Value";
entity.Property2 = 42;

context.SubmitChanges();

using (TransactionScope scope = new TransactionScope())
{
    // 更新实体
    entity.Property1 = "New Value";
    entity.Property2 = 42;

    // 提交更改
    context.SubmitChanges();

    // 如果一切正常，则提交事务
    scope.Complete();
}

using (TransactionScope scope = new TransactionScope())
{
    // 更新实体
    entity.Property1 = "New Value";
    entity.Property2 = 42;

    // 提交更改
    context.SubmitChanges();

    // 不提交事务，将回滚更改
}
