how to put images in SQL database?

  SqlConnection cn = new SqlConnection("data source=localhost;initial catalog=notitest;user id=sa;password=cos123");   cn.Open();   SqlCommand cmd = new SqlCommand("insert imgtest values(" + textBox1.Text + ",'" + ImageToBase64(pictureBox1.Image, System.Drawing.Imaging.ImageFormat.Png) + "')", cn);   SqlDataReader dr = cmd.ExecuteReader();   cn.Close(); 

SqlConnection cn = new SqlConnection("data source=localhost;initial catalog=notitest;user id=sa;password=cos123"); cn.Open(); SqlCommand cmd = new SqlCommand("select * from imgtest", cn); SqlDataReader dr = cmd.ExecuteReader(); while (dr.Read()) {     textBox2.Text = dr[0].ToString();     pictureBox2.Image = Base64ToImage(dr[1].ToString()); } cn.Close(); 

public string ImageToBase64(Image image,           System.Drawing.Imaging.ImageFormat format)         {             using (MemoryStream ms = new MemoryStream())             {                 // Convert Image to byte[]                 image.Save(ms, format);                 byte[] imageBytes = ms.ToArray();                   // Convert byte[] to Base64 String                 string base64String = Convert.ToBase64String(imageBytes);                 return base64String;             }         }           public Image Base64ToImage(string base64String)         {             // Convert Base64 String to byte[]             byte[] imageBytes = Convert.FromBase64String(base64String);             MemoryStream ms = new MemoryStream(imageBytes, 0,               imageBytes.Length);               // Convert byte[] to Image             ms.Write(imageBytes, 0, imageBytes.Length);             Image image = Image.FromStream(ms, true);             return image;         }
