Read *.csv coma separated values file and insert it in mssql database C#

Reading *.csv file values is very simple. I will show you in the next few lines :

   private void btnImportExcelToDb_Click(object sender, EventArgs e)
   {
   if (txtExcelPath.Text != "")
   {
   FileInfo f = new FileInfo(txtExcelPath.Text);
   if (f.Extension ==".csv" )
   {
   todb(numbers(txtExcelPath.Text));

   }
   else {
   MessageBox.Show( "File is not valid excel type!","WRONG FILE TYPE!",MessageBoxButtons.OK,MessageBoxIcon.Warning);
   }


   }
   }

in button event click I write check if the file that we read is file with *.csv extension and if so, then I call 2 methods that make magic :)

Method which I use for reading a values in string array of lines :

   private string[] numbers(string filepath)
   {
   string[] ar = null;
   try
   {

   using (StreamReader sr = new StreamReader(filepath))
   {
   String line;
   ar = sr.ReadToEnd().Split(new string[] { "\r\n" }, StringSplitOptions.None);

   }
   }
   catch (Exception e)
   {
   MessageBox.Show(e.Message);
   }
   return ar;
   }

"\r\n" this is line break string characters :

and after that I call another method todb(string[] ar)

a method that use string array as parameter

   private void todb(string[] ar)
   {
   con = new DataClasses1DataContext();

   int br = 0;
   for (int i = 1; i < ar.Length-1;i++ )
   {
   tbl_ImportedNumber t = new tbl_ImportedNumber();
   string[] li=ar[i].Split(';');

   t.anrede = li[0];
   t.vorname = li[1];
   t.nachname = li[2];
   t.strasse = li[3];
   t.plz = li[4];
   t.ort = li[5];
   t.gebdat = li[6];
   t.telefon0043 = li[7];
   t.telefon = li[8];
   t.land = li[9];
   t.date = DateTime.Now.Date;
   t.@checked = false;
   con.tbl_ImportedNumbers.InsertOnSubmit(t);
   con.SubmitChanges();
   br++;
   } lblCount.Text = br.ToString();
   }

in this method i read values from line and use a linq to store values in database :)
thats all code, any question ? Ask :)
