LINQ超时：超时过期

可能重复：
sql timeout expired LINQ超时：超时过期

我有一些LINQ的代码，我不敢肯定它做什么。基本上我从一些表中抽出一份报告。这个linq语句试图返回大约1.45分钟的227106条记录。当我从代码中执行它，它是给我一个“超时”异常：

An error occurred while executing the command definition. See the inner exception for details. 
    at System.Data.EntityClient.EntityCommandDefinition.ExecuteStoreCommands(EntityCommand entityCommand, CommandBehavior behavior) 
    at System.Data.Objects.Internal.ObjectQueryExecutionPlan.Execute[TResultType](ObjectContext context, ObjectParameterCollection parameterValues) 
    at System.Data.Objects.ObjectQuery`1.GetResults(Nullable`1 forMergeOption) 
    at System.Data.Objects.ObjectQuery`1.System.Collections.Generic.IEnumerable<T>.GetEnumerator() 
    at System.Data.Entity.Internal.Linq.InternalQuery`1.GetEnumerator() 
    at System.Data.Entity.Infrastructure.DbQuery`1.System.Collections.Generic.IEnumerable<TResult>.GetEnumerator() 
    at System.Collections.Generic.List`1..ctor(IEnumerable`1 collection) 
    at System.Linq.Enumerable.ToList[TSource](IEnumerable`1 source) 
    at #####.Service.TrackingLogService.GetPastDayClickingReports(Guid AffiliateID, Int32 pastDays) in ...

的代码如下：

var temp = (from l in logs 
group l by new { l.AffiliateGUIDID, l.MarketingTool, l.RefereceURL } into g 
       select new ClickingReportItem 
       { 
        Name = g.Key.MarketingTool.Title, 
        MediaType = g.Key.MarketingTool.MediaType.Name, 
        RefereceURL = g.Key.RefereceURL, 
        Impressions = (g.Key.MarketingTool.ImpressionTracking.HasValue ? g.Key.MarketingTool.ImpressionTracking.Value : false) 
         ? g.Count(m => m.TrackingTypeID == (int)Contract.TrackingType.Impressions) : (int?)null, 
        Clicks = g.Count(m => m.TrackingTypeID == (int)Contract.TrackingType.Clicks), 
        Registrations = g.Count(m => m.TrackingTypeID == (int)Contract.TrackingType.Registrations), 
        Purchases = 0, 
        Commissions = 0 
       }).OrderByDescending(m => new { m.Registrations,m.Clicks,m.Impressions}).AsQueryable(); 
     return temp.ToList();

从几个职位/博客我已经尝试添加连接超时= 0到我的连接字符串，尝试连接超时= 1800没有用。

一些建议context.CommandTimeout = 240，但我不知道哪里可以在我的代码中应用CommandTimeout。

我在Linq不太好。
