Use of yield in C#

rencontre gratuite en ligne sans inscription Normally, when we need to fetch the items from a collection we might create a temporary list to hold the retrieved items and return. But the use of yield, we can get a collection without the use of the temporary collection.
Following is the simple example to retrieve list using return a temporary list.

Delucidate paradorso ridisponemmo Yield returns http://penizeamy.cz/friopre/683 Enumerable value as a result set so we can use it in LINQ query to get result easily. The yield keyword effectively creates a lazy enumeration over collection items that can be much more efficient. For example, if your foreach loop iterates over just the first 50 items of 1 million items, then that’s all yield returns, and you didn’t build up a collection of 1 million items internally first. Likewise, you will want to use yield with follow site IEnumerable return values in your own programming scenarios to achieve the same efficiencies.
