Question

Noticed some code such as

string[] ary = parms.Split(",".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);
for( int i = 0; i < ary.Length; i++)
       ary[i] = ary[i].Trim();

works fine but wondering if there is a better way to do this in one step

Answer 1

string[] trimmedStrings = parms.Split(',')
                               .Select(s => s.Trim())
                               .Where(s => s != String.Empty)
                               .ToArray();

BTW, consider using generic typed list like List<string> rather than legacy arrays

IList<string> trimmedStrings = parms.Split(',')
                                    .Select(s => s.Trim())
                                    .Where(s => s != String.Empty)
                                    .ToList();
