Question

Until now, I only had to store application state of primitive types like int, string, boolean and for that I used Properties.Settings.Default object with no problem.

But now I also need to store instances of classes created with new keyword.

So my question is how to store these types of objects?

Answer 1

Serialize your object with XmlSerializer in that way:

var p=new Person();
p.FirstName = "Jeff";
p.MI = "A";
p.LastName = "Price";
System.Xml.Serialization.XmlSerializer x = new System.Xml.Serialization.XmlSerializer(p.GetType());
x.Serialize(Console.Out, p);

Notes:

• you have to use the attribute [Serializable] (or other, it depends on the serializer) on your class
• try using POCO objects
• depending on your .NET version, consider toughts in this Codeproject article.
