title: converting from int to hex
body: <p>I want to convert some ints to hex,but i'm getting something like this : "?|???plL4?h??N{" from 12345. Why?</p>
  
  <pre><code>int t = 12345;
  
  System.Security.Cryptography.MD5CryptoServiceProvider ano = new
  System.Security.Cryptography.MD5CryptoServiceProvider();
  
  byte[] d_ano = System.Text.Encoding.ASCII.GetBytes(t.ToString());
  byte[] d_d_ano = ano.ComputeHash(d_ano);
  
  string st_data1 = System.Text.Encoding.ASCII.GetString(d_d_ano);
  string st_data = st_data1.ToString();
  </code></pre>
  
  <p>I'm using it in window form,not in console.</p>
