vb.net - changing the way of coding so that MS Excel is not to be needed to installed on server in asp.net -

-

i have started deveop website using asp.net.

i need fetch data excel display client.

i hosting site on somee.com can freely host it.

but on server of somee.com excel not installed.

i have written code website display data from excel.

dim xlapp new microsoft.office.interop.excel.application()     dim xlworkbook microsoft.office.interop.excel.workbook = xlapp.workbooks.open(fileuploadpath & sender.text)     dim xlworksheet microsoft.office.interop.excel._worksheet = xlworkbook.sheets(sheetname)     dim xlrange microsoft.office.interop.excel.range = xlworksheet.usedrange      dim rowcount integer = xlrange.rows.count     dim colcount integer = xlrange.columns.count      dim tbl new datatable()      integer = 1 rowcount         tbl.rows.add()     next      integer = 1 colcount         tbl.columns.add()     next      if rowcount > 1 or colcount > 1         integer = 1 rowcount             j integer = 1 colcount                 tbl.rows(i - 1)(j - 1) = xlrange.value2(i, j)             next j         next     end if      gvreadfiles.autogeneratecolumns = true     gvreadfiles.datasource = tbl     gvreadfiles.databind()      xlapp.activeworkbook.close(false, session(fileuploadpath & sender.text))     xlapp.quit()      xlworkbook = nothing     xlapp = nothing

now need have changes in code not excel dependent.

can me?

i solved using google more 2 hours.

here code

dim objconn oledbconnection = nothing dim dt system.data.datatable = nothing  try      dim connstring string = ""      if extension = "xls" or extension = ".xls"          connstring = "provider=microsoft.jet.oledb.4.0;data source=" & fileuploadpath & sender.text & ";extended properties=" + convert.tochar(34).tostring() + "excel 8.0;hdr=no;imex=1" + convert.tochar(34).tostring() + ""      elseif extension = "xlsx" or extension = ".xlsx"          connstring = "provider=microsoft.ace.oledb.12.0;data source=" & fileuploadpath & sender.text & ";extended properties=" + convert.tochar(34).tostring() + "excel 12.0;hdr=no;imex=1" + convert.tochar(34).tostring() + ""      end if      objconn = new oledbconnection(connstring)      objconn.open()      dt = objconn.getoledbschematable(oledbschemaguid.tables, nothing)      dim firstsheetname string = "sheet1"      if not dt nothing         dim excelsheets [string]() = new [string](dt.rows.count - 1) {}          ' add sheet name string array.         each row datarow in dt.rows             firstsheetname = row("table_name").tostring().substring(0, row("table_name").tostring.length - 1)             exit         next      end if      return firstsheetname  catch ex exception      return "sheet1"       if objconn isnot nothing         objconn.close()         objconn.dispose()     end if     if dt isnot nothing         dt.dispose()     end if  end try
