工作学习 / 学科技术讨论 / 正在用LINQ的，或者正在学LINQ的，推荐一款小软件LINQPad，附加很多例子，很实用。如果你用LINQ to SQL，想分析LINQ最终生成的SQL代码，用LINQPad轻松得到

谢谢大猫，看样子不错，明天就试试。

Don’t get any its advantage yet, I mean any LINQ query can be written in VS. Why use the separated tool?Should user copy & paste the queries to VS or what else? I get lost.

如果学习Linq，这个工具比VS更直观、友好一些，就凭那么多.Net专业人士的 Recommendations 也是值得一看的。对于高手来说当然可以不屑一顾，^_^

In my personal experience, LINQ is pretty similar to SQL. There isn’t much complicated syntax. The complicated results can only be done by experiences rather than any tools.

Yes, for a complex SQL, there are many select groups, inner join, left join, join inside another join, case statements, change column to different name, etc. WRITING SQL is challenging and fun.

I agree. BTW, I was wondering when you become more and more technique oriented?

Funny question! Are you one of those tech guru guys who believe I am not technical oriented, and don't know VERSION CONTROL at all? What a Rolia world.

Too abashed. my level is only to use some very simple one like VSS. it's not funny at all.

Are you using SVN in Eclipse, or Jdeveloper? Or !Ciao in Notes Domino? Version control is just an application of database and user /role control.

Pay attention to what BLUE said if you reply to him, okay?

I think LINQ 's syntex is not much same as sql, for example, outer left/right join, group, select ... in sub-sql, and it makes not only design time headache, but difficult to debug(sql can be simply copy into studio management and run script).

嗯，哥们提到到lazy operators确实令我很头疼，debug的时候经常不能hit设置的断点，看不到执行的步骤。俺经常的办法是用Console.WriteLine(解决，调试通过以后把Console.Write删掉。设置SubQuery是个好方法，就是太费脑子了.... ^_^

If executing time of query doesn’t matter, why don’t use greedy operators, e. g. .ToList<Object>() or .ToArray<Object>()?

ToList()或者ToArray()好象并不好使....

No any problem to hit BP, no matter using lazy or greedy opeartor!Either following case to to hit bolded line. You might need reinstall your VS.
string[] ss = new string[] {"kk","pppp","aaa" };
string[] result = ss.Where(s => s.Length > 2).ToArray();
Console.WriteLine("result");
string[] ss = new string[] {"kk","pppp","aaa" };
var = ss.Where(s => s.Length > 2);
Console.WriteLine("result");

Sorry，可能是我以前的语言表达不准确，我碰到的和Lazy Operator有关的问题是：

Sub-query is not greedy operator. It doesn’t help you for the problem you mentioned.

BTW, PLINQ may have little more options and changes in order to improve performance. You might take more attention to it.

嗯，刚刚下载了2008 6月的CPT版，大概看了一下，我的天哪！那性能提升不是一点半点，太可怕了，多核的威力..... 估计微软肯定会在.net 4.0中将集成这种Parallel Extensions。多谢兄台介绍

Great. For my daily work, I use some tools to debug or speed up. Some of them are free. Finding the right tool is a fun and rewarding process.
