Fix Code in code example???

[bixel]

I am trying to use this guy's code but I don't know enough on how to fix it - because he was a little lazy in typing it.

from here>

code that needs fixing

public enum SortDirection
{
   Ascending, Descending
}

public class ListSorter where T : class
{
  public static List Sort
(
              List listToSort,
              string propertyName,
              SortDirection direction) where P : IComparable
  {
    Type propertyType = typeof (P);
    Type comparableInterface = propertyType.GetInterface("IComparable");

    if (comparableInterface == null)
        throw new Exception("Properties to sort by must be IComparable");

    listToSort.Sort(
        delegate(T x, T y)
            {
              PropertyInfo p1 = x.GetType().GetProperty(propertyName, propertyType);
              PropertyInfo p2 = y.GetType().GetProperty(propertyName, propertyType);

              object p1objvalue = p1.GetValue(x, null);
              object p2objvalue = p2.GetValue(y, null);

              P p1value = (P)p1objvalue;
              P p2value = (P)p2objvalue;

              if (direction == SortDirection.Ascending)
                  return p1value.CompareTo(p2value);
              else
                  return p2value.CompareTo(p1value);
          });

    return listToSort;
  }
}

I was able to fix a small part of it, namely here >>

public class ListSorter<T> where T : class

but I can't solve the rest

Fix what exactly? what doesn't work? You should expect us to do the legwork for you, narrow the problem description down.
