How do I pass datetime value as a parameter to select rows from a datatable?

this is my .cs code

protected void Button_Date(object sender, EventArgs e)
{
if (Page.IsValid)
{
try
{

string dateFrom = DateFrom.Text; // textbox values
string dateto = DateTo.Text;
DateTime FromDt = DateTime.Parse(dateFrom); // parsing in date time
DateTime ToDt = DateTime.Parse(dateto);
using (OracleConnection con = new OracleConnection(ConfigurationManager.ConnectionStrings["Connection_string"].ConnectionString))
{
con.Open();
OracleCommand cmd = new OracleCommand("procfordate", con);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new OracleParameter("mycur",
OracleDbType.RefCursor)).Direction = ParameterDirection.Output;
cmd.Parameters.Add(new OracleParameter("dd1", DateFrom)); // sending in ddatabase
cmd.Parameters.Add(new OracleParameter("dd2", DateTo));
OracleDataAdapter Adp = new OracleDataAdapter(cmd);
DataSet ds = new DataSet();
Adp.Fill(ds);
con.Close();
return ds;
}
....
}}}

create or replace PROCEDURE PROCFORDATE(
MYCUR OUT SYS_REFCURSOR,
DD1 DATE,
DD2 DATE)
IS
BEGIN
OPEN MYCUR FOR
SELECT RECEIVEDDATE, O_FILENAME,
FROM Table_name WHERE RECEIVEDDATE>=DD1 and RECEIVEDDATE <=DD2
or use
