Question

我是XML的初学者，我想将学生的字段保存到XML中。但我不知道如何将“类型”保存为对象。这是我的代码：

class Student
{
    private int id;
    private string name;
    private string surname;
    public Type type;    

    public Student(int id, string name, string surname, Type type)
    {
        this.id = id;
        this.name = name;
        this.surname = surname;
        this.type = type;
    }
}

class Type
{
    private string ID;
    private string name;

    public Odbor(string ID, string name)
    {
       this.ID = ID;
       this.name= name;
    }
}

class Program
{
    static void Main(string[] args)
    { 
        Type type1 = new Type("IRT","info");
        Type type2 = new Type("MATH","mathematic");
        List<Student> Students = new List<Student>();
        Students.Add(new Student(10,"Jon","Snow", type1));
        Students.Add(new Student(11,"Ned","Stark", type2));
        //Save Students to XML
    }
}

感谢您的帮助。

您可以尝试这样的事情：注意此代码仅用于示例目的，可以做得更好

using System.Xml.Linq;

    class Student { 


            public int id;
            public string name;
            public string surname;
            public Type type;

            public Student(int id, string name, string surname, Type type)
            {
                this.id = id;
                this.name = name;
                this.surname = surname;
                this.type = type;
            }
        }


        class Type
        {
            public string ID;
            public string name;

            public Type(string ID, string name)
            {
                this.ID = ID;
                this.name = name;
            }
        }

        class Program
        {
            static void Main(string[] args)
            {
                Type type1 = new Type("IRT", "info");
                Type type2 = new Type("MATH", "mathematic");
                List<Student> Students = new List<Student>();
                Students.Add(new Student(10, "Jon", "Snow", type1));
                Students.Add(new Student(11, "Ned", "Stark", type2));
                //Save Students to XML


                XElement xmlElements = new XElement("Students");
                foreach (Student student in Students)
                {
                    var xmlstudent     = new XElement("student");
                    var xmlstudenttype = new XElement("studenttype");

                    xmlstudenttype.Add(new XAttribute("ID", student.type.ID),
                                       new XAttribute("name",student.type.name));
                    xmlstudent.Add(new XAttribute("id", student.id),
                                   new XAttribute("name", student.name),
                                   new XAttribute("surname", student.surname), 
                                   new XElement("type", xmlstudenttype));

                    xmlElements.Add(xmlstudent);
                }

                System.Console.Write(xmlElements);
                System.Console.Read();
            }
        }
