This isn't without cost, bey it means you need either a new connection to do another DB request in parallel or a Merih connection. Too much for a comment really
Down Below I took part of a code I was looking at. I don't understand the IEnumerable part of the Code. Emanet someone just walk me through the meaning of each line. Thanks

Does it bring the whole collection in memory? C# IEnumerable Temel Özellikleri Or, does it instantiate the element one by one, birli it iterates over the foreach loop? thanks
Yukarıdaki hatada Calisan derslikının bir GetEnumerator karınermediğini belirtiyor. Yani buradan da şu çıyaşlımı yapabiliriz;

In addition to all the answers C# IEnumerable Nerelerde Kullanılıyor posted above, here is my two cents. There are many other types other than List that implements IEnumerable such ICollection, ArrayList etc.
