Solution 1

have you tried to convert the array to a generic list, and use that list in the where clause?

C#

List<int> lst = new List<int>();
lst.Add(1);
lst.Add(2);
lst.Add(3);

var processes = from dtProcs in Process.GetProcesses()
             where (lst.Contains(dtProcs.Id))
             select dtProcs;

This should do the trick.

Since arrays implement IEnumerable and IEnumerable<T>, .Contains() can be used on the array directly, without converting to List<T>.
