LINQ中的Where by和Sum特定列

Question

我有这个SQL查询，它提供了我想要的结果。请帮我把它转换成LINQ。

SELECT skill, sum (skillLevel) 
FROM ReportView
WHERE jobTitle = 'Graphic Designer'
GROUP BY skill

查询给出如下结果。

  skill      (No column Name)
-------------------------------
Photoshop         10
Illustrator        8

我试过这个，但是我收到了匿名类型错误。

    var results = db.ReportViews
       .Where(x => x.jobTitle == "Graphic Designer")
       .GroupBy(x => x.skill)
       .Select(y =>
       new
       {
           skill = y.Select(x => x.skill),
           skillLevel = y.Sum(s => s.skillLevel)
       }).ToList();
