3 ways to Sort in Descending order via lambdas In C# , one can sort the List of Objects using Lambdas easily . Until now , i found the LINQ Query to be more easy to sort but after using the Lamba expression , i feel that the lambda expression can also be used effectively to sort in descending order . For example , i use the below class for the datapublic class Movie { public string MovieName { get; set; } public string Actor { get; set; } }

Normally I wouldn't consider sorting a very interesting topic, but I honestly did not know about using the minus symbol in lambda expressions. That's very handy.

I do still feel that the linq order by statement is more descriptive (and easier for maintenance programmers to understand), but having the ability to use the lambda equivalent can make for more succinct code.

That last one is particularly scary - simply swapping the x and y gives you descending order. Imagine when some comes to debug that just can't figure out why it's descending just because it's not intuitive at all :) I can see many heads bashing brick walls because of that. I'll probably still stick to Reverse() or OrderByDescending with proper Linq :)
