问题 Given the following code snippet: public class Foo { public IEnumerable<string> Sequence { get; set; } public IEnumerable<string> Bar() { foreach (string s in Sequence) yield return s; } } is the following snippet semantically equivalent, or is it different? If it is different, how do they function differently? public class Foo2 { public IEnumerable<string> Sequence { get; set; } public IEnumerable<string> Bar2() { return Sequence; } } This question is inspired by this question which is

Expose IQueryable Over WCF Service

由 点点圈 提交于 2019-11-27 05:34:28
I've been learning about IQueryable and lazy loading/deferred execution of queries. Is it possible to expose this functionality over WCF? I'd like to expose a LINQ-to-SQL service that returns an IQueryable which I can then perform additional queries on at the client, and finally execute using a .ToList(). Is OData format applicable at all in this context? If possible, what is the term for this technique and what are some good tutorials I can follow? Thank you. You should check WCF Data Services which will allow you to define Linq query on the client. WCF Data Services are probably the only

Linq - What is the quickest way to find out deferred execution or not?

由 牧云@^-^@ 提交于 2019-11-27 01:19:05
What is the quickest way to find out which .net framework linq methods (e.g .IEnumerable linq methods) are implemented using deferred execution vs. which are not implemented using deferred execution. While coding many times, I wonder if this one will be executed right way. The only way to find out is go to MSDN documentation to make sure. Would there be any quicker way, any directory, any list somewhere on the web, any cheat sheet, any other trick up your sleeve that you can share? If yes, please do so. This will help many linq noobs (like me) to make fewer mistakes. The only other option is

How exactly does <script defer=“defer”> work?

由 若如初见. 提交于 2019-11-26 08:50:14
问题 I have a few <script> elements, and the code in some of them depend on code in other <script> elements. I saw the defer attribute can come in handy here as it allows code blocks to be postponed in execution. To test it I executed this on Chrome: http://jsfiddle.net/xXZMN/. <script defer=\"defer\">alert(2);</script> <script>alert(1)</script> <script defer=\"defer\">alert(3);</script> However, it alerts 2 - 1 - 3 . Why doesn\'t it alert 1 - 2 - 3 ? 回答1: UPDATED: 2/19/2016 Consider this answer
