Update Set更新JsonMap列时出报异常

[icejd]

问题描述及重现代码：

       [JsonMap]
       public UserLoginsettingsModel user_loginsettings { get; set; } = new UserLoginsettingsModel();

return fsql.Update<TB_U_UserInfoModel>()
     .Set(a => a.user_email == model.user_email)
     .Set(a => a.user_loginsettings==model.user_loginsettings)
     .Where(a => a.userid == model.userid)
     .ExecuteAffrows()>0;
报错



用
 return fsql.Update<TB_U_UserInfoModel>()
      .SetSource(model)
      .Where(a => a.userid == model.userid)
      .ExecuteAffrows()>0;
则正常

知道问题所以了,需要new .Set(a => new { model.user_loginsettings })

[2881099]

.Set(a => a.user_loginsettings, model.user_loginsettings) 用这个呢？

[icejd]

换成这个 //.Set(a => new { user_gatesetting }) .Set(a=>a.user_gatesetting,user_gatesetting) 提示上面的错误
