) the byte array i fill, is sooner or later filled completely. but i don't know how to clear the array and when i have to clear it, or do i even have to clear it? as soon as the array is full, the program throws - of course - an exception ("ArgumentOutOfRangeException").

2) sometimes i get the same input more than one time. for example: when i join a channel and save the nicknames to the nicklist, some nicknames appear twice or even more often. what do i have to do that this doesnt happen?

List<string> nicknames = new List<string>();
...
string newNick = "Johnny Sasaki";
if(!nicknames.Contains(newNick))
{
    nicknames.Add(newNick);

Instead of calling my stored procedure n number of times in a loop how can i call the stored procedure once. I don’t want to pass the values as varchar as it is not a fixed length. I am not going to have high volume data and hence sqlbulkcopy is not required. Is there another way?
