不用继承接口,一样可以把一个没有继承接口的类来实例化接口

public interface IName 
    {
        int Age { get; set; }
        string Name { get; set; }
    }
  
    public class Person 
    {
        public int Age{get;set;}
        public string Name { get; set; }
        public Person()
        { }
        public Person(string name,int age)
        {
            Name = name;
            Age = age;
        }
    }
  
    public class EmptyEntity : IName
    {
        public string Name { get; set; }
        public int Age { get; set; }
    }
  
    public class ClassToInterface
    {
        /// <summary>
        /// 
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <typeparam name="TResult">it implements the interface.</typeparam>
        /// <returns></returns>
        public static IName ConvertClassToInterface<T>(T obj)
        {
            IName entity=new EmptyEntity();
            PropertyInfo[] descProperties = typeof(IName).GetProperties();
            Type type = obj.GetType();
            foreach(PropertyInfo propertyInfo in descProperties)
            {
                propertyInfo.SetValue(entity,type.GetProperty(propertyInfo.Name).GetValue(obj, null), null);
            }
            Console.WriteLine("Result:{0}={1}",entity.Name,entity.Age);
            return entity;
        }
  
    }
