Question

I am having a bit of trouble getting this c# code to work I can get it to work if I use the console.write that I have commented out but I can get those same results stored in this array for me to use in a different section of my program.

FileInfo[] selectionFileOrder;
     for (int index = 0; index < dateAllOrder.Length; index++)
     {
          if (dateAllOrder[index].LastAccessTime.Month == DateTime.Now.Month)
          {
               int i = 0;
               i++;
               selectionFileOrder[i] = dateAllOrder[index];
               // Console.Write("{1}. {0}", dateAllOrder[index].Name, index);
               // Console.Write(" ({0}) ", dateAllOrder[index].Length);
               Console.WriteLine();
          }
      }

I have looked at google and can’t seem to find any answers to my issue I know that it is the variable selectionFileOrder that is unsigned but I don’t have anything to assign to it. Any fresh ideas would be helpful

Thanks

You need to initialize the array:

FileInfo[] selectionFileOrder = new FileInfo[dateAllOrder.Length];

or better, use a List:

IList<FileInfo> selectionFileOrder = new List<FileInfo>();
foreach(FileInfo item in dateAllOrder)
{
     if (item.LastAccessTime.Month == DateTime.Now.Month)
     {
          selectionFileOrder.Add(item);
          // Console.Write("{1}. {0}", dateAllOrder[index].Name, index);
          // Console.Write(" ({0}) ", dateAllOrder[index].Length);
          Console.WriteLine();
     }
}

Or best, use LINQ!
