我有一个 LINQ 查询,它返回与我的 PictureGallery
类匹配的结果。我需要将它们加载到我的 ViewModel
但我收到以下错误:
Cannot implicitly convert type 'System.Linq.IQueryable' to 'System.Collections.Generic.IEnumerable'. An explicit conversion exists (are you missing a cast?)
我是 C# 的新手。如何将“结果”转换到我的“PictureGallery”viewmddel 类中?
提前致谢!
Controller :
//Test MediaID
var MediaID = 75;
//Query Results
var Results = from g in DB.Galleries
join m in DB.Media on g.GalleryID equals m.GalleryID
where g.GalleryID == GalleryID
orderby m.MediaDate descending, m.MediaID descending
select new { g.GalleryTitle, Media = m };
//Create my viewmodel
var Model = new GalleryViewModel
{
MediaID = MediaID,
PictureGallery = Results, //This line throws the error.
PictureCount = Results.Count()
};
View 模型:
public class GalleryViewModel
{
public int? MediaID { get; set; }
public IEnumerable<PictureGallery> PictureGallery { get; set; }
public int PictureCount { get; set; }
}
public class PictureGallery
{
public int GalleryID { get; set; }
public string GalleryTitle { get; set; }
public int MediaID { get; set; }
public string MediaTitle { get; set; }
public string MediaDesc { get; set; }
public double Rating { get; set; }
public int Views { get; set; }
}
最佳答案
将您的查询改写为:
//Query Results
var Results = from g in DB.Galleries
join m in DB.Media on g.GalleryID equals m.GalleryID
where g.GalleryID == GalleryID
orderby m.MediaDate descending, m.MediaID descending
select new PictureGallery {
GalleryID = g.GalleryId,
GalleryTitle = g.GalleryTitle,
MediaID = m.MediaID,
MediaTitle = m.MediaTitle,
MediaDesc = m.MediaDesc,
Rating = m.Rating,
Views = m.Views} ;
