C#实体类转换的两种方式小结

//学生类 ??
private class Student
{
? ? public string name { get; set; }
? ? public int age { get; set; }
? ? public string className { get; set; }
?
}
//教师类
private class Teacher
{
? ? public string name { get; set; }
? ? public int age { get; set; }
? ? public string sex { get; set; }
}
//给学生类赋值
?Student student = new Student
?{
? ? ?name = "张三",
? ? ?age = 20,
? ? ?className = "六"
?};
?//泛型+反射方式
?Teacher teacher = ConvertModel<Teacher, Student>(student);
?Console.WriteLine(teacher.name);//张三
?Console.WriteLine(teacher.age);//20
?Console.WriteLine(teacher.sex);
?
?//JSON序列化方式
?teacher = null;
?string json = JsonConvert.SerializeObject(student);
?teacher = JsonConvert.DeserializeObject<Teacher>(json);
?Console.WriteLine(teacher.name);//张三
?Console.WriteLine(teacher.age); //20
?Console.WriteLine(teacher.sex);
?
?
?//泛型+反射
public static T ConvertModel<T, P>(P pModel)
{
? ? T ret = System.Activator.CreateInstance<T>();
?
? ? List<PropertyInfo> p_pis = pModel.GetType().GetProperties().ToList();
? ? PropertyInfo[] t_pis = typeof(T).GetProperties();
?
? ? foreach (PropertyInfo pi in t_pis)
? ? {
? ? ? ? //可写入数据
? ? ? ? if (pi.CanWrite)
? ? ? ? {
? ? ? ? ? ? //忽略大小写
? ? ? ? ? ? var name = p_pis.Find(s => s.Name.ToLower() == pi.Name.ToLower());
? ? ? ? ? ? if (name != null && pi.PropertyType.Name == name.PropertyType.Name)
? ? ? ? ? ? {
? ? ? ? ? ? ? ? pi.SetValue(ret, name.GetValue(pModel, null), null);
? ? ? ? ? ? }
?
? ? ? ? }
? ? }
?
? ? return ret;
}

string jsonstr = JsonConvert.SerializeObject(model);
