Best part about this video is “IEnumberable is the question and not the answer.” Such a great point, and helps to understand the movenext concept under the covers.

After searching for what seemed like hundreds of C# beginner intro tutorials so I understood basic stuff so I could get more confident in diving into the docs, I wanted to say that this series has been a lifesaver. You two are great at what you do. Don't stop! Keep making even more tutorials together whether it be certain things about C# or continuing this series. You two just have such a great chemistry where you switch roles between student and teacher and often ask questions to each other we are thinking to ourselves while we are learning. Fantastic job guys.

5:34 Interpolation. 8:47 Cat var nums = new List() { 14, 200, 83, 94, 5 }; var queries = from num in nums orderby num ascending where num < 90 select num; queries.ToList().ForEach(x => Console.WriteLine($"Num: {x}")); Console.WriteLine(queries.Count()); // queries made Console.WriteLine();

what

@AthelstanEngland 14 дней назад

Is LINQ slower in operation than simply iterating through the original list? For most instances I guess it doesn't matter but for a larger dataset and perhaps several where clauses is it significant?

i don't know why, it will ber very readable if the LINQ Query update to "select score in scores where score > 80 order score descending" because it use multiple time "score" from score, at the end select score. uhh so weird 😒

First time hearing David Fowler talk... definitely not what I was expecting him to sound like 😅 But great lesson though.

List names = ["Sam", "John", "Xavior", "Ash", "Mick"]; names.Sort(); IEnumerable namesQuery = from name in names select name; Console.WriteLine($"There are {names.Count()} names"); foreach (string s in names) { Console.WriteLine($"The name {s} has {s.Length} letters "); } this was really fun to write but how do i get only name with more than like 4 letters

@jessedv5915 2 месяца назад

Is Linq still applicable if you use Strings like me?

@John-Dawg677 Месяц назад

Inside your foreach, you can add an IF statement enclosing the console writeline foreach (string s in names) { *if(s.Length > 4)* Console.WriteLine($"The name {s} has {s.Length} letters "); }
