Ich arbeite an einer ASP.NET-Anwendung, in der eine Seite mit zwei Auswahlfeldern ist. Eine für die Suche nach allen Personen in der ausgewählten Abteilung und eine für die Suche nach Personen mit dem angegebenen Namen (oder einen Teil davon mit LIKE). Für jedes Auswahlfeld erhalte ich eine Abfrage, die ein IQueryable-Objekt derselben Framework-Entität erhält. Aber wenn ich versuche, die IQueryable-Objekte und ihre Ergebnisse mit Intersect (wegen AND-Logic) zu kombinieren, wird nur die erste Abfrage behandelt und die zweite nicht. Was habe ich falsch gemacht? Vielleicht gibt es einen Fehler in meinen Abfragen?Kombinieren von zwei IQueryables funktioniert nicht
Hier sind die Anfragen:
Die ersten für die Personen, an die ausgewählten Abteilung suchen.

Und die zweite Abfrage dient dazu, Personen nach dem gegebenen Namen zu suchen.
