无法从用法中推导出方法“System.Data.Linq.Table<MvcTest.Models.Dinner>.InsertAllOnSubmit<TSubEntity>(System.Colle

今天学习MVC，编写实例过程中遇到这个错误，后来才发现方法调用错误。

public  NerdDinnerDataContext db = new NerdDinnerDataContext();

/// <summary>
        /// 插入一条新Dinner 
        /// </summary>
        /// <param name="article">DInner实体</param>
        public void NewPost(Dinner dinner)
        { 
           db.Dinner.InsertAllOnSubmit(dinner);

           db.SubmitChanges(); 
        }

//////改为：db.Dinner.InsertOnSubmit(dinner);

其实InsertAllOnSubmit和InsertOnSubmit方法都是ITable类中的

比较：

      void InsertAllOnSubmit(
                IEnumerable entities
          )
     void InsertOnSubmit(
               Object entity
          )
