[Javed Jahangiri]

I want to import Excel File Data in oracle table using C#. I have fetched the data from excel file but getting problem on transfering this data into oracle table.Below is my code:

string filpath = "";
string fname = "";
if (flUpload.HasFile)
{
filpath = flUpload.ResolveClientUrl(flUpload.PostedFile.File Name);
fname = flUpload.FileName.ToString();
Int32 indx = flUpload.FileName.LastIndexOf(".");
String ext = flUpload.FileName.Substring(indx + 1);

if (ext == "xls" || ext == "xlsx")
{
//Connection String to Excel
string excelConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + filpath + ";Extended Properties=\"Excel 8.0;HDR=YES;IMEX=1\"";

//Create Connection to Excel
OleDbConnection Connection = new OleDbConnection(excelConnectionString);

//Create OleDbCommand to fetch data from Excel
OleDbCommand Command = new OleDbCommand("Select [UserADID], [UserName], [mailid] FROM [Mentor Expert Users$] where [UserADID] is not null", Connection);
Connection.Open();
OleDbDataReader dr = Command.ExecuteReader();

OracleBulkCopy bulkcopy = new OracleBulkCopy(GetConnectionString());
bulkcopy.DestinationTableName = "TBL_USER_ACCOUNTS";
bulkcopy.WriteToServer(dr);

Connection.Close();
}
