我正在使用 Massive 并有一个成员表。在我的成员类中，我有一个通过电子邮件查找成员的 find 方法：

   public class Members : DynamicModel
    {
        public Members(): base("TSConnection", "Members", "Id"){}

        public dynamic Find(string email)
        {
            dynamic result = new ExpandoObject();
            result.Success = false;
            try
            {
                result.Member = this.Single(where: "Email=@0", args: email);
                result.Success = result.Member != null;
            }
            catch (Exception ex)
            {
                result.Message = ex.Message;
            }
            return result;
        }
}

这将按预期返回所有内容，并在单独的单元测试测试中result.Member.Id显示它已填充数据。

在一个单独的类中，地址。我尝试使用此方法检查用户是否存在并检索 Member.Id 以在为特定成员插入地址时使用：

 public class Addresses : DynamicModel
    {
        public Addresses() : base("TS", "Addresses", "Id") { }

        public dynamic Create(string email, string type, string address1, string address2, string city, string state, int countryId, string postcode)
        {
            var members = new Members();
            dynamic result = new ExpandoObject();
            result.Success = false;
            //var member = members.Find(email);

            result.Member = members.Single(where: "Email=@0", args: email);
            dynamic address = new ExpandoObject();

            if (result.Member != null)
            {
                address.Id = this.Insert(new {
                    MemberId = result.Member.Id,  
                    AddressTypeId = (int)AddressType.Account,
                    Address1 = address1,
                    Address2 = address2,
                    City = city,
                    State = state,
                    Country = countryId,
                    Postcode = postcode
                });
                result.Address = address.Id != 0 ? address : null;
                result.Success = address.Id != 0;
            }
            return result;
        }
}

var member = members.Find(email);当我尝试访问时，在读取此内容的选项卡式行上返回 RuntimeBinderException member.Member.Id。我进入代码，Find 方法正在“返回”正确的数据，但它没有被传递给变量成员。奇怪的是，当我使用代码在下面的行中检索用户时：

result.Member = members.Single(where: "Email=@0", args: email);

它工作正常。不过，这对于保持干燥并不是很好。发生了什么事，有没有办法可以在 Addresses 类中使用 Members 类中的 Find 方法？

这是因为您正在返回result, from Find, 这是一个ExpandoObject. 要访问Memberin，Addresses您需要将代码更改为：

var members = new Members();
var result = members.Find(email);
var member = result.Member;
