示例1: TweetGroup
public TweetGroup(IGrouping<ITweet, ITweet> tg)
{
GroupStatusIDs = tg.Select(g => g.StatusID).ToList();
CreatedOn = DateTime.Now;
StatusID = tg.Key.StatusID;
TweetText = tg.Key.TweetText;
CreatedAt = tg.Key.CreatedAt;
TweetTime = tg.Key.TweetTime;
RetweetCount = tg.Key.RetweetCount + tg.Where(t => t.User.ScreenName != tg.Key.User.ScreenName).Sum(t => t.RetweetCount);
LinkRetweetCount = tg.SelectMany(x => x.Links).Sum(x => x.UrlTweetCount);
LinkFacebookShareCount = tg.SelectMany(x => x.Links).Sum(x => x.UrlFacebookShareCount);
User = tg.Key.User;
Links = tg.Where(t => t.User.ScreenName != tg.Key.User.ScreenName).SelectMany(x => x.Links).ToList();
Links.AddRange(tg.Key.Links.Where(l => l.Image != null || l.Video != null));
}示例2: CreateOneNamespaceDeclaration
private static MemberDeclarationSyntax CreateOneNamespaceDeclaration(IGrouping<string, NamespaceDeclarationSyntax> ns)
{
var nameSyntax = SyntaxFactory.ParseName(ns.Key);
return SyntaxFactory
.NamespaceDeclaration(nameSyntax)
.AddMembers(ns.SelectMany(x => x.Members)
.ToArray());
}示例3: ComputeOffsetBetweenEvents
private DataAroundEvent[] ComputeOffsetBetweenEvents(IGrouping<string, DataAroundEvent>[] orderEventGroups, IGrouping<string, DataAroundEvent> midGroup)
{
// compute offset between each event to center group
DataAroundEvent[] repivotEvents;
repivotEvents = orderEventGroups.SelectMany(@group =>
@group.Select(d =>
{
var eventPicked = @group.OrderByDescending(e => e.EventDate).FirstOrDefault(g => g.EventDate > DateTime.Today.AddDays(-numberOfPointsAroundEvent));
int busDayDiff = 0;
if (eventPicked != null)
{
busDayDiff = BusDayDiff(midGroup.OrderByDescending(e => e.EventDate).First(x => x.EventDate > DateTime.Today.AddDays(-numberOfPointsAroundEvent)).EventDate, eventPicked.EventDate);
}
var ar = new DataAroundEvent(d.EventDate, d.Instrument, d.RawData, d.NumPointsAroundEvent, d.EventCode, busDayDiff)
{
PivotIndex = pivotIndex,
};
return ar;
})).ToArray();
return repivotEvents;
