Linq to Sql外键关系

Question

表名：Author

• AuthorID - ＆gt;主键
• 姓
• 名字

表名：Titles

• ISBN - ＆gt;主键
• BOOKTITLE
• EditionNumber
• 版权

表名：AuthorISBN

• ISBN - ＆gt;外键
• AuthorID - ＆gt;外键

下面的代码块如何不触发intellisense，因为Linq-to-SQL会根据外键关系自动创建属性？在我的情况下它不...

错误：

  

title.AuthorISBN

中当前上下文中不存在名称标题      

这不是让我添加照片，但是“作者”与AuthorISBN有“一对多”关系，“标题”与AuthorISBN有“一对多”的关系

代码：

 BooksDataContext database = new BooksDataContext();
 var authorsAndTitles =
          from title in database.Titles
          from book in title.AuthorISBN
          let author = book.Author
          orderby author.LastName, aurthor.FirstName, title.BookTitle
          select new { author.FirstName, author.LastName, title.BookTitle };

Answer 1

好像你写了一个拼写错误：

 var authorsAndTitles =
          from title in database.Titles
          from book in **tilte**.AuthorISBN
          let author = book.Author
          orderby author.LastName, aurthor.FirstName, title.BookTitle
          select new { author.FirstName, author.LastName, title.BookTitle };

不应该是title.AuthorISBN insteand of tilte.AuthorISBN？我用**包围了这个词。

除此之外，我会尝试这个：

var authorsAndTitles =
          from title in database.Titles
          let author = title.AuthorISBN.Author
          orderby author.LastName, aurthor.FirstName, title.BookTitle
          select new { author.FirstName, author.LastName, title.BookTitle };

新尝试：

var authorsAndTitles =
          from autISBN in database.AuthorISBN
          let author = autISBN.Author
          let title = autISBN.Titles
          orderby author.LastName, author.FirstName, title.BookTitle
          select new { author.FirstName, author.LastName, title.BookTitle };
