奇怪的部分是这个System.IndexOutOfRangeException：col_0_0_我无法弄清楚为什么会发生。 如有必要，我可以使用一些xml映射更新帖子。

答案 0 :(得分：1)
当我尝试将空值映射到不可为空的属性（即整数）时，我遇到了这个错误。确保你确保sql值不可为空，或者只是让c＃属性为nullable（public virtual int? NumberOfPoints { get; set; }）
答案 1 :(得分：0)
我不知道原因。但是映射中有一些奇怪的东西：Activity有属性＆＃34; Name＆＃34;，它已经映射到基类中。这可能导致指数超出范围。周围可能存在更多问题。
要非常小心像＃34; Actors＆＃34;它是多对多的，不指定表名。定义另一个＆＃34; Actors＆＃34;的风险很高。设置会产生冲突的表定义。
无关紧要：有些集应该是反向的，因为有一个元素到父元素的引用。
