我如何以匿名类型返回列表,因为我得到了这个代码

"找不到类型或命名空间名称'T'(您是否缺少using指令或程序集引用？)"

我只需要返回IdMember和UserName,谢谢

    public static List<T> GetMembersItems(string ProjectGuid)
    {
        using (PMEntities context = new PMEntities("name=PMEntities"))
        {
            var items = context.Knowledge_Project_Members.Include("Knowledge_Project").Include("Profile_Information")
                        .Where(p => p.Knowledge_Project.Guid == ProjectGuid)
                        .Select(row => new { IdMember = row.IdMember, UserName = row.Profile_Information.UserName });

            return items.ToList();
        }
    }

我正在创建一个控件,在数据源中接收DataSet或List

我如何在CreateChildControls事件中将IEnumerable转换为List？

protected override int CreateChildControls(IEnumerable dataSource, bool dataBinding)
{
    if (dataSource is System.Data.DataSet)
    {
    }
    else if(dataSource is IList)
    {
    }
}

我用这个代码

var items2 = from item in context.Images
             where item.Reported != true
             select item;

但是在"报告"列中没有返回空值为什么？
