C#

Im trying to make an app, that i can download my mails from my account.

For the test i have 4 mails, total 200kb. When i download the mails, it takes 30 secs.. aprox.. A LOT! and i dont know how to improve the velocity.


Thanks!


The code that i use to download is this:

ns = networkstream from a TCP, buffer 8192.
private string getemailtest2(int indexservidor)
        {
            StringBuilder resp1 = new StringBuilder();
            bool begin = true;
           
            int compa = 8193;
            System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
            while (true)
            {
                byte[] dataaleer = new byte[8192];
                if (ns.DataAvailable || begin)
                {
                    int a = ns.Read(dataaleer, 0, 8192);
                }
                resp1.Append(enc.GetString(dataaleer).Trim('\0'));
                if (begin)
                {
                    compa = Int32.Parse(resp1.ToString().Split(' ')[1]);
                    begin = false;
                }
                int leng = enc.GetBytes(resp1.ToString()).Length;
                if (leng >= compa)
                {
                    if (!ns.DataAvailable)
                    {
                        break;
                    }
                }

            }
            return resp1.ToString();

private void button1_Click(object sender, EventArgs e)
{
      for (int j = 0; j < 5; j++)
      {
          zoomOutPicture((j + 1) * 10);
          System.Threading.Thread.Sleep(1000);
      }
}

private void zoomOutPicture(int zoomF)
{
      int myHeight = 100+zoomF;
      int myWith = 70 + (int)Math.Round(zoomF * .7, 0);

      System.Drawing.Size test;
      test = new System.Drawing.Size(myWith, myHeight);
      myPictureBox.Size = test;
}
