how to detect double-key board (like double key-Enter) With ReactiveUI
How about this:
doubleEnter = someWindow.Events().KeyUp
.Where(x => x.EventArgs.Key == Key.Enter)
.Buffer(TimeSpan.FromMilliseconds(650), RxApp.MainThreadScheduler)
.Where(x => x.Length > 1);

Here's an example of my code thus far.
#string.Join(", ", #piece.PieceThemes.Select(t => t.Theme.Title).ToArray())
I would like to order the array in descending order. I found that .OrderByDescending() exists, but I'm having trouble understanding how to use it.
Any help is appreciated!
you provide a lamda function to specify the property to sort by
#string.Join(", ", #piece.PieceThemes.Select(t => t.Theme.Title).OrderByDescending(x=> x).ToArray())
in this case x is a string and you can just sort by it.

The complete code is as follows
if (CurrentThreadScheduler.Instance.ScheduleRequired)
{
CurrentThreadScheduler.Instance.Schedule(this, (_, me) => subscription.Disposable = me.Run(observer, subscription, s => sink.Disposable = s));
}
else
{
subscription.Disposable = this.Run(observer, subscription, s => sink.Disposable = s);
}
In this example, me is just a range variable. It is not a special syntax. It could just as easily have been named x.

DataRow row = tableWith100Rows.AsEnumerable()
.FirstOrDefault(r => r.Field<int>("ID") == 4711);
if(row != null)
row.SetField("ColumnToUpdate", "new value");

Select * from table
where Numero_Operacion in
(
Select Numero_Operacion from table
group by Numero_Operacion
having count(Numero_Operacion)>1
)
THANKS!
It would be something like this
<Table>.GroupBy(x => x.Numero_Operacion)
.Where(x => x.Count() > 1)
.SelectMany(x => x)
