System.Data.OleDb.OleDbCommand.ExecuteCommandTextForSingleResult(tagDBPARAMS dbParams,Object&executeResult)的System.Data.OleDb.OleDbCommand.ExecuteCommandTextErrorHandling(OleDbHResult hr)处于System.Data的

{
   OleDbConnection con = new 
   OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\\database_for_kissan_Pashu_AhaR_Bills.mdb");

   //  OleDbConnection oleDbConnection = new            OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\Users\\Checkout-1\\Documents\\contact.accdb");    
   OleDbCommand update = new OleDbCommand("UPDATE Customers  SET Balance = '" + balance + "',  WHERE id = " + id …
