  • Question

  • What I did Yet :- 

            public void GetBusiness(Int64 ID)
                List<Business> listEmployees = new List<Business>();

                    using (SqlConnection connection = new SqlConnection(GetConnectionString()))
                        SqlCommand sqlcom = new SqlCommand("[GetBusiness]", connection);
                        sqlcom.CommandType = CommandType.StoredProcedure;
                        sqlcom.Parameters.AddWithValue("@ID", ID);
                        SqlDataReader rdr = sqlcom.ExecuteReader();
                        while (rdr.Read())
                            Business business = new Business();
                            business.ID = Convert.ToInt64(rdr["ID"]);
                            business.BusinessName = rdr["BusinessName"].ToString();
                            business.FirstName = rdr["FirstName"].ToString();
                            business.LastName = rdr["LastName"].ToString();
                            business.Address = rdr["Address"].ToString();
                            business.City = rdr["City"].ToString();
                            business.State = rdr["State"].ToString();
                            business.Country = rdr["Country"].ToString();
                            business.EmailID = rdr["EmailID"].ToString();
                            business.ContactNumber = rdr["ContactNumber"].ToString();
                            business.AppDownloaded = rdr["AppDownloaded"].ToString();
                            business.AppUpgrade = rdr["AppUpgrade"].ToString();
                            business.AppVersion = rdr["AppVersion"].ToString();
                            business.CreatedDate = rdr["CreatedDate"].ToString();
                            business.RowStatus = Convert.ToInt16(rdr["RowStatus"]);
                            business.UserName = rdr["UserName"].ToString();
                            business.AdminPassword = rdr["AdminPassword"].ToString();
                            business.IPAddress = rdr["IPAddress"].ToString();
                            business.BusinessLogo = Convert.ToBase64String(rdr["BusinessLogo"]); 

                    JavaScriptSerializer js = new JavaScriptSerializer();
                catch (Exception ex)
                    JavaScriptSerializer a = new JavaScriptSerializer();
                    var varResult = new { result = "Error", Error = ex };

                               Now i am Getting Error on :-      business.BusinessLogo = Convert.ToBase64String(rdr["BusinessLogo"]);

  • Hi AnkitSoni29,

    Please convert it to Byte[] first, then convert it to Base64String like this:

    business.BusinessLogo =  Convert.ToBase64String((byte[])rdr["BusinessLogo"]);
