将linq表达式压缩为一个简单blog系统的表达式

我现在有很多linq表达式嵌套在foreach循环中。。。有点挫败了使用linq的意义!

我试图实现的是一个简单的博客模型(博客文章有多个标签,并与多个类别。。。仅此而已)。

var blogs = 
    from blog in db.BlogPosts
    join categories in db.BlogCategories
        on blog.Fk_Category_Id equals category.Id
    // Using a junction table because blogs can have multiple tags,
    // and tags can be shared across different blogs.
    join juncTags in db.Junc_BlogTags
        on blog.Id equals juncTags.Fk_BlogPost_Id
    join tags in db.Tags
        on juncTags.FK_Tag_Id equals tags.Id
    select new
    {
        blog,
        categories,
        tags
    };

foreach(var blog in blogs)
{
    blog.blog // Correct, can obtain information of current blog...
    blog.categories // Correct, shows the information of Blog's category
    blog.tags // Wrong, only refers to the first tag - next itteration will 
    // show the same blog with the next tag .. not what I want.
}

我确信我在这里遗漏了一些简单的东西,但是我无法理解,并且认为堆栈溢出能够很容易地回答这个问题。

提前谢谢!
