This is my current try catch statement. I dont know why it exists when empty file read in:

 // convert each string into an integer and store in "eachInt[]"

      string fileContents = System.IO.File.ReadAllText(fileName);

      string[] eachString = fileContents.Split(new char[] { '\t', '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries);

      int[] eachInt = new int[eachString.Length];

      try

      {

        for (int i = 0; i < eachString.Length; i++)

        {

          if (IsNumeric(eachString[i]))

          {

            eachInt[i] = int.Parse(eachString[i]);

          }

          // else

          //{

           // continue;

          //}

        }

        eachInt = eachInt.Where(val => val != 0).ToArray();

      }

      catch(IndexOutOfRangeException)

      {

        MessageBox.Show("File contained no integers, try a different file.");

        return;

      }
