对于强类型，初始化var值为null

我正在尝试做以下事情:

我不确定如何初始化resultcllist，因为我不能将其设置为null。

    var resultCLlist = null;
    if (RdoStatus.SelectedValue == "Incomplete")
    {
         resultCLList = (from ms in db.ver_ServiceReport
                            join gc in db.map_Sit 
                            on ms.SiteId equals gc.SiteID
                            where gc.CompanyId == companyId
                            select new ServiceReport
                            {
                                VerificationId = ms.VerificationId,
                                SiteId = ms.SiteId,
                            }
                         ).ToList();
    }
    else
    {
         resultCLList = (from ms in db.ver_ServiceReport
                            join gc in db.map_Sites
                            on ms.SiteId equals gc.SiteID
                            where gc.CompanyId == companyId
                            select new ServiceReport
                            {
                                VerificationId = ms.VerificationId,
                                SiteId = ms.SiteId,
                                SiteName = gc.SiteName,
                                TimeStamp = ms.TimeStamp,
                                EntryDate = ms.EntryDate,
                                Supplier = ms.Supplier
                            }
                        ).ToList();
    }
