Generic Extension Method Problem

I'm trying to extend a wrapper of generic objects ('Retreival' in the example below) to output as a generic list, but I can't get it to work. The generic identifiers aren't recognized?
public static class Exts
    {
        public static List<T> ToList(this  Retrieval<T> lstToUse)
        {
            List<T> lstRet = new List<T>();
            foreach(T item   in  lstToUse.Results<T>)
            {
                lstRet.Add(item);
            }
            return lstRet;
        }
    }

assuming your retrival class is something like
public class Retrieval<T>
    {
        public IEnumerable<T> Results
        {
            get;
            set;
        }
    }

seethe modified code below

public static class Ext
    {
        public static List<T> ToList<T>(this  Retrieval<T> lstToUse)
        {
            List<T> lstRet = new List<T>();
            foreach (T item in lstToUse.Results)
            {
                lstRet.Add(item);
            }
            return lstRet;
        }
    }

Hi Silas2,

I am a little unclear on what you are trying to achieve here. This might work for you. If not, can you please give some more info on the design and requirement behind this functionality?
public static class Exts
    {
        public static List<T> ToList<T>(List<T> input)
        {
            List<T> list = new List<T>();
            foreach (T item in input)
            {
                list.Add(item);
            }
            return list;
        }

    }

public static List<T> Clone<T>(this List<T> _list)
            where T : ICloneable
        {
            List<T> newList = new List<T>();

            foreach (T item in _list)
                newList.Add((T) item.Clone());

            return newList;
        }

public class Retreival : ICloneable
{
public object Clone()
        {
            return MemberwiseClone();
        }
}

Cloning is safer as your code just copies the reference unless you really intended that.
