MVC4 元数据 this.CreateTime为什么找不到

[legu1]

[MetadataType(typeof(MemberMetadata))]
public partial class Member
{
private class MemberMetadata
{
public int ID { get; set; }
[Required(ErrorMessage = "请输入帐号")]
[StringLength(50, ErrorMessage = "请勿输入超过50个字")]
[DisplayName("账号")]
public string Account { get; set; }
[Required(ErrorMessage = "请输入密码")]
[StringLength(50, ErrorMessage = "请勿输入超过50个字")]
[DisplayName("密码")]
public string password { get; set; }

public DateTime CreateTime { get; set; }
}
partial void OnCreated()
{

this.CreateTime = DateTime.Now;//为什么找不到this.CreateTime
}
｝

引用 楼主 legu1 的回复:

[MetadataType(typeof(MemberMetadata))] public partial class Member { private class MemberMetadata { public int ID { get; set; } [Required(ErrorMessage = "请输入帐号")] [StringLength(50, ErrorMessage = "请勿输入超过50个字")] [DisplayName("账号")] public string Account { get; set; } [Required(ErrorMessage = "请输入密码")] [StringLength(50, ErrorMessage = "请勿输入超过50个字")] [DisplayName("密码")] public string password { get; set; } public DateTime CreateTime { get; set; } } partial void OnCreated() { this.CreateTime = DateTime.Now;//为什么找不到this.CreateTime } ｝

this.CreateTime ---> this 实质是Member，不是MemberMetadata

[MetadataType(typeof(MemberMetadata))]
     public partial class Member
     {
         private class MemberMetadata
         {
             public int ID { get; set; }
             [Required(ErrorMessage = "请输入帐号")]
             [StringLength(50, ErrorMessage = "请勿输入超过50个字")]
             [DisplayName("账号")]
             public string Account { get; set; }
             [Required(ErrorMessage = "请输入密码")]
             [StringLength(50, ErrorMessage = "请勿输入超过50个字")]
             [DisplayName("密码")]
             public string password { get; set; }
           
             public DateTime CreateTime { get; set; }
         
            partial void OnCreated()
            {
             
                this.CreateTime = DateTime.Now;//为什么找不到this.CreateTime
            }
        }
｝
