推荐答案

NavigationService.RemoveBackEntry() 仅从 backstack 中删除最后一个条目，因此它应该适合您的需要.

NavigationService.RemoveBackEntry() removes only the last entry from the backstack, so it should fit your needs.

此方法用于从返回堆栈中删除最近的条目，如果没有更多条目要删除，则抛出 InvalidOperationException.如果要删除多个项目，请多次调用此方法.

This method is used to remove the most recent entry from the back stack, or throws an InvalidOperationException if there are no more entries to remove. If you want to remove more than one item, you call this method multiple times.
