You should use the TypeDescriptor class: public static T Convert<T>(this string input) { try { var converter = TypeDescriptor.GetConverter(typeof(T)); if(converter != null) { // Cast ConvertFromString(string text) : object to (T) return (T)converter.ConvertFromString(input); } return default(T); } catch (NotSupportedException) { return default(T); } }
