Question

我正在尝试将LINQ查询的输出保存到通用列表中，该列表是包含get和set的类的类型，但是它向我显示了无法隐式转换的错误，我搜索了许多解决方案对它而言对我没有帮助。以下是LINQ查询和泛型类定义。

LINQ查询：

public function checkmodel($model, $product_id=0) {
  if (!$model) {return false; }
    $sql = "SELECT * FROM `".DB_PREFIX."product` WHERE model='".$this->db->escape($model)."' AND sku='" AND product_id<>'".(int)$product_id."'";
    $query = $this->db->query($sql);
    return $query->rows;

类：

var posts = from p in db.Posts join c in db.Comments
  on p.Post_ID equals c.postID 
  into PostComments
  select new { PostId = p.Post_ID, Post = p.Post1, cmtcount = PostComments.Count() }

我只是像posts.ToList（）;

那样进行转换

Answer 1

var posts = from p in db.Posts join c in db.Comments
            on p.Post_ID equals c.postID 
            into PostComments
             select new Class1 
                     { 
                         PostId = p.Post_ID, 
                         Post = p.Post1, 
                         cmtcount = PostComments.Count() 
                      };
