Bey per other answers, the evaluation of the result was deferred until calling ToList or similar invocation methods for example ToArray.

Bir program süresince çeşitli data koleksiyonları kullanıldığında, bu koleksiyonlardaki verilere erişmek ve işlem kılmak gereklidir. IEnumerator, bu noktada devreye girerek koleksiyonların elemanlarını hareketsiz biricik dolaşmamızı ve muamelat yapmamızı katkısızlar.

I have writen about custom IEnumerator. Whats the simplest way to make IEnumerable from it ? ülkü solution (one line of code) would be if there was some class for that purpose. Or do I have to create my own ?

Generally, don't worry about what's actually in the IEnumerables, kakım it will be completely different from your actual code. Only worry about C# IStructuralComparable Kullanımı the actual output when you iterate over it :)

Then you'll never have more than one line of the file in memory at a time, and if you finish the loop earlier (perhaps it was a search and you found what you needed) you might not need to read the whole file. Or if you're reading the results from a large SQL query you güç limit your memory use to a single record.
