C# 实体类转换的两种方式

以下提供两种方式，一种是序列化，一种是泛型+反射；

实现功能：

    两个实体类数据转换赋值

开发环境：

    开发工具： Visual Studio 2013

    .NET Framework版本：4.5

实现代码：

 

    //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;
    }
