asp.net mvc 2如何利用MvcPager对查询结果进行分页

Question

        public PagedList<CauseInfo> GetCauseInfo(string causeValue,int pageId)
        {
            var HWMDb = new HWMDataClassDataContext();
            var selectResult = from c in HWMDb.CauseInfo
                               where c.cau_name.Contains(causeValue)
                               select new
                               {
                                   cau_id = c.cau_id,
                                   cau_name = c.cau_name
                               };           // return (new PagedList<CauseInfo>((IList<CauseInfo>)selectResult,pageId,MyAccountBLL.PageSize));          
        }selectResult 为查询结果，但无论如何也不能将其转化为IList<CauseInfo>类型；

刚想到了一种方法        public PagedList<CauseInfo> GetCauseInfo(string causeValue,int? pageId)
        {
            if (causeValue == null) causeValue = "";
            var HWMDb = new HWMDataClassDataContext();
            var selectResult = from c in HWMDb.CauseInfo
                               where c.cau_name.Contains(causeValue)
                               select new
                               {
                                   cau_id = c.cau_id,
                                   cau_name = c.cau_name
                               };
            IList<CauseInfo> ilist = new List<CauseInfo>();
            foreach (var i in selectResult)
            {
                CauseInfo causeinfo = new CauseInfo();
                causeinfo.cau_id = i.cau_id;
                causeinfo.cau_name = i.cau_name;
                ilist.Add(causeinfo);
            }
            PagedList<CauseInfo> causeInfo = 
                new PagedList<CauseInfo>(ilist, pageId??1, MyAccountBLL.PageSize);
            return (causeInfo);          
        }但有            PagedList<CauseInfo> causeInfo = 
                new PagedList<CauseInfo>(ilist, pageId??1, MyAccountBLL.PageSize);
这里有异常，求解
