c# - 当数据源为 Linq 时访问 ItemDataBound 事件中的列

Question

我使用以下代码设置数据源:

    protected void Page_Load(object sender, EventArgs e)
    {
        var vacancies = from v in db.Vacancies
                    join c in db.Customers on v.CustomerID equals c.CustomerID
                    join cp in db.CustomerPortals on c.CustomerID equals cp.CustomerID
                    where cp.PortalID == Master.Portal.ID
                    select new
                    {
                        Title = v.Title,
                        Internship = (v.ContractID == 6),
                        Hours = v.Hours,
                        City = v.Customer.City.Name,
                        Degree = v.Degree.Title,
                        Contract = v.Contract.Title,
                        CustomerID = v.CustomerID
                    };
        rVacancies.ItemDataBound += new RepeaterItemEventHandler(rVacancies_ItemDataBound);
        rVacancies.DataSource = vacancies;
        rVacancies.DataBind();
    }

现在我想知道如何从 ItemDataBound 事件访问其中一列(如 CustomerID)。

    void rVacancies_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
         // This doesnt seem to work, row would be null even though e.Item.DataItem has a value.
         DataRow row = (DataRow)e.Item.DataItem;
    }

我发现 e.Item.DataItem 包含我查询中的所有字段并且 e.Item.DataItem 的类型是

f__AnonymousType8<string,bool,byte,string,string,string,long>

终于找到了，就这么简单:

long customerID = long.Parse(DataBinder.Eval(e.Item.DataItem, "CustomerID").ToString());
