1:先添加一个classOutput.cs类
public string Name { get; set; }
public List<TemplateList> TemplateLists;
public class TemplateList
{
public int Id { get; set; }
public string Name { get; set; }
}
2
var result = (from m in this.Context.ClassOutput
group m by m.Name into lists
select new TemplateOutput
{
TemplateName = lists.Key,
TemplateLists = (from n in lists
select new TemplateList
{
Id = n.Id,
TemplateName = n.TemplateName,
}).ToList()
}
);
