您可以将结构集合存储在 XML 文件中，该文件是结构化文本。
这是一个非常快速的示例，可帮助您入门:

    using System.Collections.Generic;
    using System.IO;
    using System.Xml;
    using System.Xml.Serialization;

    public class Student {
        [XmlElement("id")]
        public int id;
        [XmlElement("name")]
        public string name;
    }

    [XmlRoot("students")]
    public class Students {
        [XmlElement("students")]
        public List<Student> students = new List<Student>();
    }

    class Program {
        static void Main(string[] args) {
            Students s = new Students();
            s.students.Add(new Student() { id = 1, name = "John Doe" });
            s.students.Add(new Student() { id = 2, name = "Jane Doe" });
            XmlSerializer xs = new XmlSerializer(typeof(Students));
            using (FileStream fs = new FileStream("students.xml", FileMode.Create, FileAccess.Write)) {
                xs.Serialize(fs, s);
            }
        }
    }

你会得到这样的东西:

<?xml version="1.0"?>
<students xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <students>
    <id>1</id>
    <name>John Doe</name>
  </students>
  <students>
    <id>2</id>
    <name>Jane Doe</name>
  </students>
</students>
