使用MVC4 EF Linq获取foreach列表循环的时候遇到了如下的问题：报错提示
There is already an open DataReader associated with this Connection which must be closed first
解决方法如下红色所示：
@foreach (var item in Model.ToList())
{
@Html.ActionLink(@item.user.nickname + "(微信)", "../Mess/MessInfo", new { id = item.id })
}
将Model改成Model.ToList()的就ok了
