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

Why do many philosophers consider a past-eternal universe to be self-explanatory but not a universe that began with no cause?

The primary difference is that the LINQ operators for IQueryable take Expression objects instead of delegates, meaning the custom query logic it receives, e.g., a predicate or value selector, is in the form of an expression tree instead of a delegate to a method.

Oluşturduğunuz klası, koleksiyon oluştururken veya alınlaştırma gerektiren öbür senaryolarda kullanabilirsiniz.

Now what makes IEnumerable really stand out is iterator blocks (the yield keyword in C#). Iterator blocks implement the IEnumerable interface like a List or an Array, but they're very special because unlike a List or Array, they often only hold the state for a single item at a time. So if you want to loop over the lines in a very large file, for example, you gönül write an iterator block to handle the file input.

IMHO, there should have been an IMultipassEnumerable, inheriting IEnumerable, which would support Reset and guarantee that multiple passes will either return identical data or throw an exception; an ordinary IEnumerable whose collection was modified should be allowed to return 'sensible' data if it's able to do so or throw an exception if it güç't, and an C# IEnumerable Nedir ISafeEnumerable, which would be expected to work sensibly (without throwing an exception) even if a collection changes. A bit C# IEnumerable Kullanımı late now to change things, though.

Here is a very good article that details the differences between statement lambdas and expression lambdas and discusses the concepts of expression tress in C# IEnumerable Nerelerde Kullanılıyor greater depth: Revisiting C# delegates, expression trees, and lambda statements vs. lambda expressions.."

Expression trees are a very important construct in C# and on the .NET ortam. (They are important C# IEnumerable Kullanımı in general, but C# makes them very useful.) To better understand the difference, I recommend reading about the differences between expressions

On the flip side, it is usually best to declare a method’s return type by using the strongest type possible (trying derece to commit yourself to a specific type). Share Follow
