public void InsertDates()
{
   string item1 = "01/01/2012";
   string item2 = "01/01/2013";
   string item3 = "03/06/2012";
   string item4 = "03/06/2011";
   string item5 = "03/06/2013";

   if (item1 != String.Empty && item2 != String.Empty && item3 != String.Empty && item4 != String.Empty && item5 != String.Empty)
   {
      DateTime tm1 = Convert.ToDateTime(item1);
      DateTime tm2 = Convert.ToDateTime(item2);
      DateTime tm3 = Convert.ToDateTime(item3);
      DateTime tm4 = Convert.ToDateTime(item4);
      DateTime tm5 = Convert.ToDateTime(item5);
      if (tm3 > tm1 && tm3 < tm2)
      {
         MessageBox.Show("item3 is in 2012");
      }
      else
      {
         MessageBox.Show("item3 is not in 2012");
      }
      if (tm4 > tm1 && tm4 < tm2)
      {
         MessageBox.Show("item4 is in 2012");
      }
      else
      {
         MessageBox.Show("item4 is not in 2012");
      }
      if (tm5 > tm1 && tm5 < tm2)
      {
         MessageBox.Show("item5 is in 2012");
      }
      else
      {
         MessageBox.Show("item5 is not in 2012");
      }
   }
}

string item1 = "01/01/2012";
string item2 = "01/01/2012";
string item3 = "03/06/2012";
string item4 = "03/06/2011";

string[] dates = new string[]{item1,item2,item3,item4};
string year2012=string.Empty;
string otherYears = string.Empty;
foreach (string date in dates)
{
    if (Regex.IsMatch(date,@".*/\s*2012", RegexOptions.CultureInvariant))
        year2012 += string.Format("{0}{1}",
                        string.IsNullOrEmpty(year2012)? "" : ", ",date);
    else
        otherYears += string.Format("{0}{1}",
                        string.IsNullOrEmpty(otherYears)? "" : ", ",date);

}
Console.WriteLine (year2012);
Console.WriteLine (otherYears);

//Output
//01/01/2012, 01/01/2012, 03/06/2012
//03/06/2011
