Can you explain what deferred execution means in LINQ?
Deferred execution in LINQ means that the evaluation of a query is delayed until the data is actually needed.
How does this differ from immediate execution?
Immediate execution evaluates the query right away and returns the results, while deferred execution waits until you iterate over the results.
Can you give me an example of deferred execution?
Sure! When you use methods like Where
or Select
, the query is not executed until you call ToList()
or foreach
.
What are the benefits of using deferred execution?
Benefits include improved performance and reduced memory usage, as data is only fetched when needed.
