Operator '!=' cannot be applied to operands of type 'string' and 'System.DBNull'

simply use Convert.IsDBNull(field) ? 0 : field; simples :D

Facebook locale information and cultureinfo to get country in .net

You will need this in your code behind: using System.Globalization; 'en_GB' will be replace so .net can understand the format, this was from a dynamic type, but you can use just a string if you wish. var country = CultureInfo.GetCultureInfo(locationinfo["locale"].Replace("_", "-")).EnglishName; string countryName = country; countryName = countryName.Substring(countryName.IndexOf("(") + 1, (countryName.Length - countryName.IndexOf("(")) - 2); Instead of returning 'English (United Kingdom)' it will now return 'United Kingdom' only. This has several uses, but I needed it to reference the city and country from facebook to a google map. I had the city information, but the main issue was getting a clean country name which is why this was needed because city names can appear in different countries. I will probably go into further detail as some point as to what can be achieved with these.
