Good day,

I am having trouble with the excel file that i was uploaded.. after i uploaded the excel file i want to validate each header and each datatype of it. just to make sure that my dbase has integrity.let say i have 10 columns.

Is there a way on how could i validate each header? and its data type?

here is my code for uploading

 protected void btnUpload_Click(object sender, EventArgs e)
        {
            string conn = "";
            if (FileUpload1.HasFile)
            {
                string fname = Path.GetFileName(FileUpload1.PostedFile.FileName);
                string fExtension = Path.GetExtension(FileUpload1.PostedFile.FileName);
                string fLocation = Server.MapPath("/ExcelFileUpload/" + fname);


                if (fExtension == ".xls")
                {
                    conn = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fLocation + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\"";
                }
                else if (fExtension == ".xlsx")
                {
                    conn = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fLocation + ";Extended Properties=\"Excel 12.0;HDR=Yes;IMEX=2\"";
                }

                else if (fExtension != ".xlsx" || fExtension != "xls" || fExtension == String.Empty)
                {

                    return;
                }


                FileUpload1.SaveAs(fLocation);

                OleDbConnection con = new OleDbConnection(conn);
                OleDbCommand cmd = new OleDbCommand();
                cmd.CommandType = CommandType.Text;
                cmd.Connection = con;
                OleDbDataAdapter dAdapter = new OleDbDataAdapter(cmd);
                DataTable dtCOO9Report = new DataTable();
                con.Open();
                DataTable dtExcelsheetName = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
                string getExcelSheetName = dtExcelsheetName.Rows[0]["TABLE_NAME"].ToString();
                cmd.CommandText = "Select * from [" + getExcelSheetName + "]";
                dAdapter.SelectCommand = cmd;

                DataSet ds = new DataSet("dsExcelC009ReportRecords");
                dAdapter.Fill(ds, "dtExcelC009ReportRecords");

                foreach (DataColumn dc in ds.Tables["dtExcelC009ReportRecords"].Columns)
                {
                    dc.ColumnMapping = MappingType.Attribute;
                }


                con.Close();

               _c009ReportEntities.xmlC009Report = ds.GetXml();
                try
                {


                    if (_c009ReportBll.InsertXMLC009Report(_c009ReportEntities) != 0)
                    {

                        GridView1.DataSource = ds;
                        GridView1.DataBind();

                    }
                }
                catch (Exception err)
                {
                    lblMsg.Visible = true;
                    lblMsg.Text = "Error in " + err.ToString();
                }

                //else
                //{

                //    return;
                //}
            }
        }
