binding blob with picturebox

Question

Hi,
I'm a beginer in c sharp and I can't pass over a problem. I would like to bind a blob field (mysql) with a picturebox in c sharp;

here is the code:

1. string query = "Select name,director,picture from Movies where Movies.name='" + search + "'";
2.                 //create command and assign the query and connection from the constructor
3.                 MySqlCommand cmd = new MySqlCommand(query, connection);
4.  
5.                 //Execute command
6.                 MySqlDataReader dr;
7.  
8.                 dr = cmd.ExecuteReader();
9.                 if (dr.HasRows)
10.                 {
11.                     while (dr.Read())
12.                     {
13.                         txtname.Text = (dr["Name"] + "");
14.                         txtdirector.Text = (dr["Director"] + "");
15.                         txtactors.Text = (dr["Actors"] + " "");
16.                     }
17.                 }
18.                 else
19.                     MessageBox.Show("The movie is unavailable");

What shall I do to extract the picture form database and put it in a picturebox
like I put the other fields in textbox ?  If anybody know, I would like an exact answer not a link,
 because I use mysql not sql and because I already done a lot of searching on this topic bu
 without succes.

thank you in advance
