Reader Error

[Memnoch1207]

I am getting a couple of errors in my page_load event

First Error:
Cannot implicitly convert type 'int' to 'System.Data.SqlClient.SqlDataReader'

Second Error:
Operator '>=' cannot be applied to operands of type 'object' and 'int'

any ideas??? I am trying to return a count from the sql query, then check with the reader if that count is greater than 2.

private void Page_Load(object sender, System.EventArgs e)
{
   string strConn = "Data Source=localhost;uid=steve;pwd=xxxxxx;Initial Catalog=mansion";
   SqlConnection Conn = new SqlConnection(strConn);
   SqlCommand Comm = new SqlCommand("SELECT rDate, COUNT(rDate) AS 'count' FROM reservations GROUP BY(rDate) HAVING COUNT(rDate) > 1", Conn);
   SqlDataReader reader;

   reader = Comm.ExecuteNonQuery();<------ First Error 

   while(reader.Read())
   {
      if(reader["count"] >= 2)<------------ Second Error
      {
         Calendar1.SelectedDates.Add(Convert.ToDateTime(reader["rDate"]));
      }
   }
			
reader.Close();
Conn.Close();

Conn = null;
}

I got it figured out.

First Error: ExecuteNonQuery() is used for Insert, update and delete, not when a query will return rows...So I changed it to ExecuteReader();

Second Error: The reader returns an object type field, so to get the integer value in "count" you have to convert it to an integer

Convert.ToInt32(reader["count"]);

and that fixed the problem!
