[mmdullah]

Hi all, I can not retrive the elements from a hashtable in the same order as they are added. please help......

Hashtable htParameters = new Hashtable();
htParameters.Add("fromDate", string.Format("'{0}'",fromDate.ToString("dd-MMM-yyyy")));
htParameters.Add("ToDate", string.Format("'{0}'",toDate.ToString("dd-MMM-yyyy")));
htParameters.Add("dtOvdDate", string.Format("'{0}'",dtOvdDate.ToString("dd-MMM-yyyy")));
htParameters.Add("dtOvdDatePrev", string.Format("'{0}'",dtOvdDatePrev.ToString("dd-MMM-yyyy")));
htParameters.Add("strAndPaid", string.Format("'{0}'",strAndPaid));
htParameters.Add("rdoFileInfoSpecific", string.Format("{0}",rdoFileInfoSpecific.Checked?"1":"0"));
htParameters.Add("SpecificFileNo", string.Format("'{0}'",txtFileInfoSpecific.Text.Trim()));
htParameters.Add("strAndFOfficer", string.Format("'{0}'",strAndFOfficer));
htParameters.Add("strAndZone", string.Format("'{0}'",strAndZone));
htParameters.Add("strCollType", string.Format("'{0}'",strCollType));
htParameters.Add("rdoStatusNID", string.Format("{0}",rdoStatusNID.Checked?"1":"0"));
htParameters.Add("rdoStatusBankOpen", string.Format("{0}",rdoStatusBankOpen.Checked?"1":"0"));
htParameters.Add("chkOvdVal", string.Format("{0}","0"));
htParameters.Add("rdoRepTypeAllDet", string.Format("{0}",rdoRepTypeAllDet.Checked?"1":"0"));

when retrieving..... they comes in different order

if (parameters != null && parameters.Count > 0)
{
foreach (string parametername in parameters.Keys)
{
SqlParameter param = new SqlParameter("@" + parametername, parameters[parametername]);
Cmnd.Parameters.Add(param);

                }

This is in the nature of the hashtable. all elements are sorted by the hash of the key as mention here: http://msdn.microsoft.com/en-us/library/system.collections.hashtable.aspx[^] "Represents a collection of key/value pairs that are organized based on the hash code of the key." Use List< KeyValuePair< T,T > > for that unless you need an efficient by-key retrieval And please post code that compiles for others, like keep consistent field names (what is parameters?) and post code that works without rewriting all of your format variables.
