Need some C# ArrayList For loop help!

[Daten]

I have a loop that looks like this

int i;
for (i = 0; i < FriendsArray.Count; i++)
 
{
 
    MessageBox.Show("Im in the loop " + key);
 
    if (FriendsArray.BinarySearch(key) >= 0)
    {
         MessageBox.Show("Key Found " + key);
    }
    else
    {
        FriendsArray.Add(key);
        tabAdded = tabs.Add(key, AVName);
        MessageBox.Show("Key Not Found " + key);
    }
}
 

now you can all probobaly see something seriously wrong with that. all i want todo is know if there is a key in my ArrayList, if there is then do nothing. but if there is not then add a key. add my tab. and show the msg it was not found. i cant figure this out for the life of me <im new to C# but picking it up fast>
Thank you in advance :)

I don't see anything wrong with that as long as your array is sorted and each of the elements in it implement the IComparable interface

Well I do not see the point of the loop. It will do the same thing each time. Why do you use the loop?

im used to working in an event based scripting language and that would be ho wi had to search a list. i know C# is different and there may be another way but im not sure . i think i know why this loop does not work. my array is always empty

The BinarySearch method you called also does the looping for you. There is no need to loop through the array if you are using it.
