如何将LINQ数据绑定到下拉列表

protected void BindMarketCodes()
{
    using(var dc = new LINQOmniDataContext())
    {
        dd2.DataSource = from p in db.lkpMarketCodes
                         orderby 0
                         select new {p.marketName, p.marketCodeID };
        dd2.DataTextField = "marketName";
        dd2.DataValueField = "marketCodeID";
        dd2.DataBind();
    }
}

// no need to use ToList()
// no need to use a temp list;
// using an anonymous type will limit the columns in your resulting SQL select
// make sure to wrap in a using block;

请参阅下面的修订代码

protected void BindMarketCodes()
{    
    using (var dataContext = new LINQOmniDataContext()) {
        //bind to Country COde droplist
        dd2.DataSource = from p in dataContext.lkpMarketCodes 
            orderby p.marketName
            select new {p.marketCodeID, p.marketName};
        dd2.DataTextField = "marketName";
        dd2.DataValueField = "marketCodeID";
        dd2.DataBind();
    }
}
