父类转换为子类

C# 父类转换为子类公有方法

public static class ClassConvertor
    {
        /// <summary>
        /// 父类对象转为子类对象 
        /// </summary>
        /// <typeparam name="TChild"></typeparam>
        /// <typeparam name="TParent"></typeparam>
        /// <param name="parent"></param>
        /// <returns></returns>
        public static TChild ConvertChild<TChild, TParent>(TChild child,TParent parent) where TChild : TParent, new()
        {
            var parentType = typeof(TParent);
            var properties = parentType.GetProperties();
            foreach (var propertity in properties)
            {
                if (propertity.CanRead && propertity.CanWrite)
                {
                    propertity.SetValue(child, propertity.GetValue(parent, null), null);
                }
            }
            return child;
        }
    }

调用

var child = ClassConvertor.ConvertChild<Child,Parent>(p, new Child());
//然后再给child的自有属性复制
