一个新语法糖

注意： 如果是调用对象中的方法，就要用委托的那种方式

 

            List<NovelBook> bookList = new List<NovelBook>();
            bookList.Add(new NovelBook { BookID = 100, BookName = "1" });
            bookList.Add(new NovelBook { BookID = 200, BookName = "1" });
            bookList.Add(new NovelBook { BookID = 300, BookName = "1" });
            bookList.Add(new NovelBook { BookID = 400, BookName = "1" });
            bookList.Add(new NovelBook { BookID = 500, BookName = "1" });
            bookList.Add(new NovelBook { BookID = 600, BookName = "1" });
            bookList.Add(new NovelBook { BookID = 700, BookName = "1" });
            bookList.Add(new NovelBook { BookID = 800, BookName = "1" });
            bookList.Add(new NovelBook { BookID = 900, BookName = "1" });

            long i = 0;
            bookList.ForEach(delegate(NovelBook book) { i += book.BookID; });

            long j = 0;
            bookList.ForEach(x=> j+=x.BookID);

            Console.WriteLine(i);

            Console.WriteLine(j);
