I use c# 4 asp.net and EF 4. I'm precompiling a query, the result should be a collection of Anonymous Type.
At the moment I use this code.
public static readonly Func<CmsConnectionStringEntityDataModel, string, dynamic>
queryContentsList =
CompiledQuery.Compile<CmsConnectionStringEntityDataModel, string, dynamic>
(
(ctx, TypeContent) => ctx.CmsContents.Where(c => c.TypeContent == TypeContent
& c.IsPublished == true & c.IsDeleted == false)
.Select(cnt => new
{
cnt.Title,
cnt.TitleUrl,
cnt.ContentId,
cnt.TypeContent, cnt.Summary
}
)
.OrderByDescending(c => c.ContentId));
I suspect the RETURN for the FUNCTION Dynamic does not work properly and I get this error
Sequence contains more than one element enter code here.
I suppose I need to return for my function a Collection of Anonymous Types...
Do you have any idea how to do it? What I'm doing wrong? Please post a sample of code thanks!
Update:
public class ConcTypeContents
{
public string Title { get; set; }
public string TitleUrl { get; set; }
public int ContentId { get; set; }
public string TypeContent { get; set; }
public string Summary { get; set; }
}
public static readonly Func<CmsConnectionStringEntityDataModel, string, ConcTypeContents> queryContentsList =
CompiledQuery.Compile<CmsConnectionStringEntityDataModel, string, ConcTypeContents>(
(ctx, TypeContent) => ctx.CmsContents.Where(c => c.TypeContent == TypeContent & c.IsPublished == true & c.IsDeleted == false)
.Select(cnt => new ConcTypeContents { cnt.Title, cnt.TitleUrl, cnt.ContentId, cnt.TypeContent, cnt.Summary }).OrderByDescending(c => c.ContentId));
