Here is a quick example that shows how to serialize/deserialize a struct to xml file: using System; using System.IO; using System.Runtime.Serialization; using System.Runtime.Serialization.Formatters.Soap; public class PersistStruct { [Serializable] struct Day { public string Name; public Day(string name){ this.Name = name;} } static void Main() { Day myDay = new Day(Long Day); FileStream stream = new FileStream(@d:\struct.xml FileMode.Create); SoapFormatter formater = new SoapFormatter(); formater.Serialize(stream myDay); stream.Close(); FileStream newStream = new FileStream(@d:\struct.xml FileMode.Open); Day newDay = (Day)formater.Deserialize(newStream); Console.WriteLine(newDay.Name); } }

Should be using xml serialization. By the way is there any way that I can read formatted data from an ascii file? For example for the file 12 abc 3.45 can I use something like scanf(%d %s %f) to read? Thanks
