Extension method to determine if a list is ordered asc

IListOfTExtensions.cs

public static class IListOfTExtensions
{
   public static bool IsOrdered<T, T2>(this IList<T> @this, Func<T, T2> orderedOnProperty) 
      where T2 : IComparable<T2>

      var isLessThanOrEqualTo = true;

      for (int i = 1; i < @this.Count; i++)

         var comparer = Comparer<T2>.Default;

	 isLessThanOrEqualTo = comparer
	    .Compare(orderedOnProperty(@this[i - 1]), orderedOnProperty(@this[i])) <= 0;

	 if (!isLessThanOrEqualTo)
	 {
	    break;

// var isOrdered = fooList.IsOrdered(x => x.Bar)
