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;

        }

  

    }
