Comparing two arraylist in c# windows application

I have the arraylist which has some process names like "Notepad", "mspaint"

I want to check the values of above arraylist against the following :

Process[] Procs = Process.GetProcesses();

If the process "Notepad" is not there in Procs, then i want to use that value for further requirement.

How do i find the value of my arraylist which is missing in Procs ??

Or you could use the Except method provided by LINQ. But if you are using Arraylist instead of List<>, I guess you are using .NET 1.

1) Go through the list one-by-one using ArrayList.Contains

2) If LINQ is available use the set difference: Except()

There are smarter answers, but i will post a naive one because its easier to understand

List<string> myprocs; // populated with process names
Process[] Procs = Process.GetProcesses();
foreach(Process proc in Procs)
{
  if(myprocs.Contains(proc.ProcessName))
  {
     myprocs.Remove(proc.ProcessName);
  }
}
// whatever that is left over in myprocs at this point is your remainder process names.
