2 1 Aşağıdaki kütüphaneleri ekleyiniz. using System.Data.SqlClient; using System.IO.Ports; using System.IO; using System.Drawing.Imaging; using System.Data.OleDb; Solution explorer bölmesinde referanslara sağ tıklayıp Microsoft. Office. Interop. Excel ekleyiniz. Global değişkenler double t, sayi; int sample; double sample_rate; DataTable tablo = new DataTable(); string veri = "0"; int str; Form_Load kodları t = 0; sayi = 0; tablo.columns.add("tarih"); tablo.columns.add("saat"); tablo.columns.add("zaman"); tablo.columns.add("veri"); str = 0;
