Pemindai kode batang mendekode kode menjadi desimal (3 digit) jika saya menggunakan evtkeyupeven

Pemindai kode batang “pemindai logika data pemindaian cepat qd2430 ” membaca kode dalam format teks ketika saya memfokuskan kotak teks apa pun tetapi kode tersebut didekode menjadi Desimal (3 digit) jika saya menggunakan evtKeyUpEvent

jadi, itu mengubah kode ini “33378755971180” ke “051 051 051 055 056 055 053 053 057 055 049 049 056 048“

Apa yang saya coba:

private string BarCode = "";
   private void evtKeyUpEvent(object sender, KeyEventArgs e)

   {
       if (Keys.NumPad0 <= e.KeyCode && e.KeyCode <= Keys.NumPad9)
       {
           BuildBarCode((e.KeyCode - Keys.NumPad0).ToString());
       }
       else if (Keys.D0 <= e.KeyCode && e.KeyCode <= Keys.D9)
       {

           BuildBarCode((e.KeyCode - Keys.D0).ToString());
       }
       if (65 <= e.KeyValue && e.KeyValue <= 90)
       {
           BuildBarCode((e.KeyCode).ToString());
       }
       else if (Keys.ShiftKey == e.KeyCode)
       {
       }
       else if (Keys.OemPeriod == e.KeyCode)
       {
           BuildBarCode(".");
       }
       else if (Keys.Multiply == e.KeyCode)
       {
           BuildBarCode("*");
       }
       else if (Keys.Add == e.KeyCode)
       {
           BuildBarCode("+");
       }
       else if (Keys.Separator == e.KeyCode)
       {
           BuildBarCode("|");
       }
       else if (Keys.Subtract == e.KeyCode)
       {
           BuildBarCode("-");
       }
       else if (Keys.Divide == e.KeyCode)
       {
           BuildBarCode("/");
       }
       else if (Keys.OemBackslash == e.KeyCode)
       {
           BuildBarCode(@"\");
       }
       else if (Keys.Separator == e.KeyCode)
       {
           BuildBarCode(",");
       }
       else if (Keys.OemMinus == e.KeyCode)
       {
           BuildBarCode("-");
       }

       else if (Keys.Space == e.KeyCode)
       {
           BuildBarCode(" ");
       }
       else if (Keys.OemCloseBrackets == e.KeyCode)
       {
           BuildBarCode(")");
       }
       else if (Keys.OemOpenBrackets == e.KeyCode)
       {
           BuildBarCode("(");
       }
       else if (Keys.Oemtilde == e.KeyCode)
       {
           BuildBarCode("~");
       }

       else if (Keys.Oemcomma == e.KeyCode)
       {
           BuildBarCode(",");
       }
       else if (Keys.OemSemicolon == e.KeyCode)
       {
           BuildBarCode(";");
       }
       else if (Keys.OemSemicolon == e.KeyCode)
       {
           BuildBarCode(";");
       }


       else if (e.KeyCode == Keys.Enter || e.KeyCode == Keys.Return)
       {
           updateUIBarCode(BarCode);
       }
   }
   private void BuildBarCode(string value)
   {
       BarCode = string.Concat(BarCode, value);
   }
   public void updateUIBarCode(string i)
   {
       AddNewRowWithCode(i);
   }
