將圖片以二進位制形式存入資料庫時,首先要在資料庫中建立一張表,將儲存圖片的欄位型別設為Image型別,用FileStream類、BinaryReader把圖片讀成位元組的形式,賦給一個位元組陣列,然後用ADO.SqlCommand物件的ExecuteNonQuery()方法來把資料儲存到資料庫中。主要程式碼如下：

    private void button1_Clickobject sender, EventArgs e) { openFileDialog1.Filter = "*jpg|*.JPG|*.GIF|*.GIF|*.BMP|*.BMP"; if(openFileDialog1.ShowDialog()==DialogResult.OK) { 　　　　 string fullpath =openFileDialog1.FileName;//檔案路徑 　 FileStream fs = new FileStream(fullpath, FileMode.Open); byte[] imagebytes =new byte[fs.Length]; BinaryReader br = new BinaryReader(fs); imagebytes = br.ReadBytes(Convert.ToInt32(fs.Length)); //資料庫連線 SqlConnection con = new SqlConnection("server=(local);uid=sa;pwd=;database=db_05"); con.Open(); SqlCommand com = new SqlCommand("insert into tb_08 values(@ImageList)",con); com.Parameters.Add("ImageList", SqlDbType.Image); com.Parameters["ImageList"].Value = imagebytes; com.ExecuteNonQuery(); con.Close(); } }
