比如我有两个类，这两个类除了类名不一样，其他成员都一样。现在要把其中一个IEnumerable泛型的类转换成另一个IEnumerable泛型类，应该怎么转呢？
IEnumerable<ProductClass> as IEnumerable<Class> //as是不行的
public partial class Category
{
// Primitive properties
public int ClassID { get; set; }
public string ClassName { get; set; }
public Nullable<int> ParentID { get; set; }
public string ParentPath { get; set; }
public Nullable<int> Depth { get; set; }
public Nullable<int> RootID { get; set; }
public Nullable<int> Child { get; set; }
public Nullable<int> PrevID { get; set; }
public Nullable<int> NextID { get; set; }
public Nullable<int> OrderID { get; set; }
public string Title { get; set; }
public string KeyWords { get; set; }
public string Description { get; set; }
public string Content { get; set; }
public Nullable<byte> ShowType { get; set; }
public string LinkUrl { get; set; }
public string Intro { get; set; }
public string ClassPic { get; set; }
public string ItemPic { get; set; }
public Nullable<byte> LanType { get; set; }
public Nullable<bool> IsHome { get; set; }
}
