switch (ds.Tables[0].Rows[0]["CakeName"].ToString())

参考：

  IDictionary<string, object> dic = new Dictionary<string, object>();
                dic.Add("bh", bh);
                Bitmap bitmap = cardHelper.GetZP(dic);
                this.pictureBox1.Image = bitmap;

/// <summary>
        /// 根据条件查询照片
        /// </summary>
        /// <param name="dic">查询条件封装的字典</param>
        /// <returns>照片Bitmap</returns>
        public Bitmap GetZP(IDictionary<string, object> dic)
        {
            string sql = "select * from xxb where 1=1 ";

            if (dic.ContainsKey("bh"))
            {
                sql += " and id = " + Convert.ToInt32(dic["bh"]) + "";
            }
            if (dic.ContainsKey("xm"))
            {
                sql += " and 姓名 = '" + Convert.ToString(dic["xm"]) + "'";
            }
            if (dic.ContainsKey("sfzh"))
            {
                sql += " and 证件号码 = '" + Convert.ToString(dic["sfzh"]) + "'";
            }

            using (IDataReader odr = accessOp.ExecuteReader(sql))
            {
                if (odr.Read())
                {
                    if (!string.IsNullOrEmpty(odr["照片信息"].ToString()))
                    {
                        byte[] bytes = (byte[])odr["照片信息"];

                        using (MemoryStream ms = new MemoryStream(bytes) { Position = 0 })
                        {
                            return new Bitmap(ms);
                        }
                    }
                }
            }
            return null;
        }
