两个泛型实例之间的属性变化

两个泛型实例之间的属性变化，需要借助Linq（select）以及一个新的方法，该方法接受的参数应为属性较全的泛型实例中的元素。

 

 一、类定义

public class Person
{
    public Person(string name, int age, List<string> hobbies)
    {
        Name = name;
        Age = age;
        Hobbies = hobbies;
    }
    public string Name { get; set; }
    public int Age { get; set; }
    public List<string> Hobbies { get; set; }
}

public class Student
{
    public string Name { get; set; }
    public int Age { get; set; }
    public List<string> Hobbies { get; set; }
    public List<string> Teachers { get; set; }
}

public class StudentAndTeacherRelationship
{
    public StudentAndTeacherRelationship(string studentName, List<string> teachers)
    {
        StudentName = studentName;
        Teachers = teachers;
    }
    public string StudentName { get; set; }
    public List<string> Teachers { get; set; }
}

 

 

二.具体代码

static void Main(string[] args)
{
    var ThreePerson = new List<Person>()
    {
        new Person("frankie", 22, new List<string>() {"Play basketball", "running"}),
        new Person("asan", 23, new List<string>() {"reading", "play games"}),
        new Person("Qin", 24, new List<string>() {"running", "coding"})
    };
    // 不同类型对象之间的属性映射
    Mapper.Initialize(_ => _.CreateMap<Person, Student>());
    var ThreeStudent = Mapper.Map<List<Student>>(ThreePerson);

    // 通过Linq语句和一个方法，进行泛型实例之间的属性变化
    ThreeStudent = ThreeStudent.Select(AddTeachersRelationship).ToList();
}

public static Student AddTeachersRelationship(Student stu)
{
    var studentAndTeacherRelationship = new List<StudentAndTeacherRelationship>()
    {
        new StudentAndTeacherRelationship("frankie", new List<string>() {"cb", "hongmei"}),
        new StudentAndTeacherRelationship("asan", new List<string>() {"xuyuncong", "fanguangyu"}),
        new StudentAndTeacherRelationship("Qin", new List<string>() {"liusanming", "xuyuncong"})
    };
    foreach (var item in studentAndTeacherRelationship)
    {
        if (stu.Name.Equals(item.StudentName))
        {
            stu.Teachers = item.Teachers;
        }
    }
    return stu;
}

 

 

三、结果
