XAF中实现类型转换（ValueConverter）

实现代码

 /// <summary>
    /// 测试类
    /// </summary>
    public class User : XPObject
    {
        private string login;
        private DateTime regDate;

        public string Login
        {
            get { return login; }
            set { SetPropertyValue<string>("Login", ref login, value); }
        }
        [ValueConverter(typeof(Encryption))] //类型转换
        public DateTime RegistrationDate
        {
            get { return regDate; }
            set { SetPropertyValue<DateTime>("Password", ref regDate, value); }
        }
    }

    /// <summary>
    /// 实现自己的类型转换
    /// 字符类型与日期类型换转
    /// </summary>
    public class Encryption : ValueConverter
    {
        //从显示类型转换到数据库存储类型
        public override object ConvertToStorageType(object value)
        {
            return value.ToString();
        }
        //从数据库存储类型转换到显示
        public override object ConvertFromStorageType(object value)
        {
            return Convert.ToDateTime(value);
        }
        //存储类型
        public override Type StorageType
        {
            get { return typeof(string); }
        }
    }
