C＃XMLSerializer构造函数

Question

I have this code but i don't know what should be in the constructor Klant() . What should come here so the field 'voornaam' comes in the XML?

public static void SchrijfKlanten(Klant klant, string pad) {
    using (FileStream file = File.Open(pad, FileMode.OpenOrCreate)) {
    XmlSerializer xml = new XmlSerializer(klant.GetType()); //THIS LINE
    xml.Serialize(file, klant);
    }
}

public class Klant {
    string voornaam;

    public Klant(){
        //Here
    }

Answer 1

Your field should be a public property. Other than that, it should work fine even without any constructor.

public class Klant 
{
    public string Voornaam { get; set; }
}
