LINQ query to remove a single value from a set while retaining another value

[willmotil]

well im no expert
i spent some time attempting to do this using linq but couldn't find a way

at the end of my efforts i think

your original solution is better
if its over a network there are other considerations though

i did find a excellent linq reference page though
http://code.msdn.microsoft.com/101-L...mples-3fb9811b

on further thought a delete is a request
rather then a query so it sort of makes sense
not to be able to do so within a query

maybe in the first place just query all non or delete-able items
and remove any sort of delete button when they are worked on

        static void Main(string[] args)
        {
            Program I = new Program();
            I.TestLinq01();
        }
        public void TestLinq01()
        {
            listOfuInts = new List<uint>{ 1, 2, 3, 4, 5 };
            ListToConsole("via linq before", listOfuInts);

            var query = // var is of type ienumerable from linq
                from n in listOfuInts  // loop
                where n != specialValue // conditional
                select n; // action

            listOfuInts = query.ToList<uint>(); // convert back to uint
            
            ListToConsole("after", listOfuInts);
        }
        public void ListToConsole<T>(string msg,List<T> list)
        {
            Console.WriteLine(Environment.NewLine + msg);
            foreach (var obj in list)
            {
                Console.WriteLine(obj);
            }
            Console.WriteLine(Environment.NewLine);
        }

the real pain is that the enumerable changes when you perform a delete

this was my looping solution for a delete all but special values
in truth i don't really use linq much i find it far more difficult
then just straight coding something

        // remove all not with a special value
        public void TestLoop02()
        {
            listOfuInts = new List<uint> { 1, 2, 3, 4, 5 };
            ListToConsole("via loop02 before", listOfuInts);
            int index = 0;
            while (index < listOfuInts.Count)
            {
                if (listOfuInts.ElementAt(index) != specialValue)
                {
                    listOfuInts.RemoveAt(index);
                }
                else
                {
                    index++;
                }
            }
            ListToConsole("via loop02 after remaining values not removed", listOfuInts);
        }

but linq is more for querys so...
