I implemnted an obliterator for C#. It works around this problem:

foreach (var item in list)
 if (item == "two")
   list.Remove(item);

System.InvalidOperationException: Collection was modified;enumeration operation may not execute.

The new version of the code is one line longer:

using (var obliterator = Obliterator.From(list))
  foreach (var item in list)
    if (item == "two")
      obliterator.Remove(item);

The Obliterator class :

using System;
using System.Collections.Generic;

namespace Obliterator
{
 public class Obliterator<T> : IDisposable
 {
   ICollection<T> collection;
   List<T> toRemove;

   public Obliterator(ICollection<T> collection)
   {
     this.collection = collection;
     toRemove = new List<T>();
   }

   public void Remove (T item)
   {
     toRemove.Add(item);
   }

   public void Dispose()
   {
     foreach (var item in toRemove) collection.Remove(item);
   }

 }

 public static class Obliterator
 {
   public static Obliterator<T> From <T> (ICollection<T> collection)
   {
     return new Obliterator<T> (collection);
   }
 }
}
