Databases :: Read Data From Excel

Aug 31, 2010

i had 2 columns in the excel file one is SNo and another Description

looks like below
Sno Description
1 1/2 Feet
2 1/5 Feet
3 20
4 30

i read the data from this file using below code

string strFileName = FileUpload1.PostedFile.FileName;
string connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + strFileName + ";" + "Extended Properties=Excel 8.0;";
OleDbConnection objConn = new OleDbConnection(connectionString);
objConn.Open();
String strConString = "SELECT * FROM [Product Classification 5$]";
//where date = CDate('" + DateTime.Today.ToShortDateString() + "')";
OleDbCommand objCmdSelect = new OleDbCommand(strConString, objConn);
// Create new OleDbDataAdapter that is used to build a DataSet
// based on the preceding SQL SELECT statement.
OleDbDataAdapter objAdapter1 = new OleDbDataAdapter();
// Pass the Select command to the adapter.
objAdapter1.SelectCommand = objCmdSelect;
// Create new DataSet to hold information from the worksheet.
DataSet objDataset1 = new DataSet();
objAdapter1.Fill(objDataset1, "ExcelData");

but in it doesnt read the Description data of 20 & 30 because somebody said if the first cell value is string type then all the column should be string but in mycase its coming as mixed(alpha & numeric), so that it cant read the data, i tried to convert the column as Text then also the same problem continues,
