Linq to sql DataContext中具有类型化表的LINQ到SQL继承映射
嘿，伙计们，我有一个使用类型化表的LINQ2SQL系统，但现在我尝试在2个类之间添加继承映射，我在创建DataContext实例时遇到了一个错误。错误为“输入字符串格式不正确”。我猜在我的Datacontext类中有类型化的表和我所放置的映射会有一些冲突 这是我的代码的缩写版本Linq to sql DataContext中具有类型化表的LINQ到SQL继承映射,linq-to-sql,Linq To Sql,嘿，伙计们，我有一个使用类型化表的LINQ2SQL系统，但现在我尝试在2个类之间添加继承映射，我在创建DataContext实例时遇到了一个错误。错误为“输入字符串格式不正确”。我猜在我的Datacontext类中有类型化的表和我所放置的映射会有一些冲突 这是我的代码的缩写版本 public class DataAccessHelper : DataContext { public static DataContext db; public Table<CronJob>
