Try using the .Add() function, like this:

        static void Main(string[] args)
        {
            List<string> ul = new List<string>();

            foreach (Process proc in Process.GetProcesses())
            {
                ul.Add(proc.ProcessName);
            }
        }

A List<> when created, has a default size, and in your code elements get added until that size is full (at which point the next ‘insert’ fails. The add() method checks to see if this size limit is no longer enough and increases the size of the list when required.

This code also eliminates the need for a couple of your variables.
