Convert.ToDateTime(dr("CreateDate")).ToShortDate()

See the MSDN docs for other functions available from the DateTime datatype, including custom formats available through the 'ToString' function.

Answer 3

Response.Write(DateTime.Parse(dr("CreateDate").ToString()).ToString("MM/dd/yyyy"))

Answer 4

Easy:

((DateTime)dr["CreateDate"]).ToString("MM/dd/yyyy")

// I would also check that it isn't dbnull before doing it though

if (! DBNull.Value.Equals(dr["CreateDate"])) // blah blah
