好的，所以我有一个名为“Business”的对象（我知道，我知道，“Business Business Object”）当它保存它的外键时不知何故丢失了。其他一切都在节省。我已经逐步完成了代码并跟踪了对象，直到

session.SaveOrUpdate(businessObject);

方法。那时的物体是完整的，外来的属性似乎在那里。但是，当它被保存时，外国 ID 不在业务表中。我只能想象这可能是因为我没有正确映射它们？

这是它们被映射的位置：

<many-to-one insert="false" update="false" name="_Township" column="TownshipId" class="HQData.Objects.Township, HQData" />

    <many-to-one insert="false" update="false" name="_User" column="UserId" class="HQData.Objects.User, HQData" />

    <many-to-one insert="false" update="false" name ="_SubCategory" column="SubCategoryId" class="HQData.Objects.SubCategory, HQData"/>

这是加载和保存对象的位置：

HQData.Objects.Business business = null;
            if (BusinessId != 0)
                business = BusinessManager.GetBusiness(BusinessId);
            else
                business = new HQData.Objects.Business();
            business._SubCategory = CategoryManager.GetCategory(Convert.ToInt32(ddlCategory.SelectedValue.Trim()));
            business.Name = ControlHelper.Sanitize(txtName.Text.Trim());
            business.Address1 = ControlHelper.Sanitize(txtAddress.Text.Trim());
            business._Township = TownshipManager.GetTownshipByCityorZip(ControlHelper.Sanitize(txtTownship.Text));
            business.PhoneNumber = ControlHelper.Sanitize(txtPhone.Text.Trim());
            business.FaxNumber = ControlHelper.Sanitize(txtFax.Text.Trim());
            business.Email = ControlHelper.Sanitize(txtEmail.Text.Trim());
            business.Website = ControlHelper.Sanitize(txtWebsite.Text.Trim());
            business.AboutUs = ControlHelper.Sanitize(txtAboutUs.Text.Trim());
            business._User = UserManager.GetCurrentUser();


            BusinessManager.SaveBusiness(business);

感谢您的帮助。

你是说生意吗._SubCategory.SubCategoryId

并且不确定 GetCurrentUser 返回什么，但如果 Id 也是...

业务._User.UserId？
