Question

Let\'s say I have a web page that currently accepts a single ID value via a url parameter:
http://example.com/mypage.aspx?ID=1234

I want to change it to acce

Something like this might work:

public static IList GetIdListFromString(string idList)
{
    string[] values = idList.Split(',');

    List ids = new List(values.Length);

    foreach (string s in values)
    {
        int i;

        if (int.TryParse(s, out i))
        {
            ids.Add(i);
        }
    }

    return ids;
}

Which would then be used:

string intString = "1234,4321,6789";

IList list = GetIdListFromString(intString);

foreach (int i in list)
{
    Console.WriteLine(i);
}
