内联比较有效，但如果我将其包装在一个方法中，LINQ表达式无法被翻译。

完整的源代码在底部，但这里是重点。

如果有任何方法可以避免重复代码x.ArticleId == demo.ArticleId && x.Title == demo.Title并重用一个源码吗？

            var article1 = new Article()
            {
                ArticleId = 1234,
                Title = "First",
            };
            var article2 = new Article()
            {
                ArticleId = 5678,
                Title = "Second",
            };
            var article3 = new Article()
            {
                ArticleId = 9012,
                Title = "Third",
            };
            mydb.Articles.AddRange(article1, article2, article3);
            mydb.SaveChanges();
            var demo = new WebArticle()
            {
                ArticleId = 5678,
                Title = "Second",
            };
            //使用内联代码
            if (mydb.Articles.Any(x => (x.ArticleId == demo.ArticleId && x.Title == demo.Title)))
            {
                Console.WriteLine("存在");
            }
            else
            {
                Console.WriteLine("不存在");

            //使用方法

            }
            else

    class WebArticle

        public int ArticleId { get; set; }
        public string Title { get; set; }
    }
