c# - How to add quotes around each list element after .add? -

-

मेरे पास एक सूची है 

  निजी सूची & lt; string & gt; AdditionalHeaderMeta = नई सूची & lt; स्ट्रिंग & gt; ();   
 और मैं उसे सीएसवी फ़ाइल में आउटपुट करना चाहता हूं। जो सभी काम कर रहे हैं, लेकिन यह कुछ तत्वों को जोड़ता है जो अतिरिक्त मैं हेडरमेटा में जोड़ रहा है, उनमें कभी भी अल्पविराम हो सकता है जो स्पष्ट रूप से एक सीएसवी फ़ाइल को खराब करता है  
 मैंने कोशिश की  
  additionalHeaderMeta.Select (i = & gt; "\" "+ i +" \ "");   
 लेकिन कोई भाग्य नहीं है।   
 
 
 यदि आप संशोधित करना चाहते हैं सूची में जगह, बस उस पर लूप।  
  के लिए (इंट इंडेक्स = 0; इंडेक्स लेफ्टिनेंट; सूची.काउंट; इंडेक्स ++) सूची [अनुक्रमणिका] = / * आइटम को संशोधित करें * /   
 आपने जो किया है, वह एक क्वेरी परिभाषा बनती है जो कि लाज़िली मूल्यांकन की जाएगी, लेकिन वास्तव में आपको क्वेरी पर पुनरावृति करने की आवश्यकता होगी। यदि आप वास्तव में सूची को असम्बद्धकृत छोड़ना चाहते हैं तो क्वेरी का उपयोग करें, लेकिन बस डेटा को संशोधित रूप में प्रोजेक्ट करना चाहते हैं।  
  var query = additionalHeaderMeta.Select (i = & gt; "\" " + I + "\" "); Foreach (क्वेरी में var आइटम) जो भी   
 अपनी सूची को पूरी तरह से दूसरे के साथ बदलने के लिए,  toList ()  का उपयोग क्वेरी पर करें और परिणाम को वापस प्रदान करें मूल सूची।  
  अतिरिक्तहैडरमेटा = अतिरिक्तहैडरमैटा। चयन करें (i = & gt; "\" "+ i +" \ "")। ToList ();

php - Creating canonical URLs with custom route-classes -

-
I am trying to implement the canonical url and to combine with custom route classes. URL-SACAME is something like this: / category-x / article / 123 / category-y / article / 123 I am creating a custom route - the expansion of the class Zend_Controller_Router_Route_Regex and checks that the article is 123 and the correct category-name is included in the URL. If the article is in 123 square-X and the user is reaching square-y, then I want to redirect to the correct URL. But there is no clear possibility to do this directly to the roads. What is the best practice approach here? I often do this in my action controller like something ... // Get / Category-Y / Article / 123 $ $ article- & gt; URL is generated, and it contains / category-x / article / 123 if (this-> --request-> getRequestUri ()! = $ Article-> URL) {return $ this- & gt; ; _helper-> Redirector-> GoToUrl ($ paragraph-> url); } In this example, $ article-> The url will need ...

I am trying to write a simple invoicing system. I want to use the Datetime Diff to calculate the cost of each invoice. I have so far: / * In this example $ dayLength and $ ratePerSec is not really the case, but now we use the hypotethical values ​​of 8.0 and 0.0054 Will * / $ date1 = new date time ("Time 1 Form Database", [DateTimeJonof Chase]); $ Date2 = new date time ("Time 2 Form Database", [Datetime Joneof Choice]); $ Diff = $ date2- & gt; Diff ($ date1); $ LenInSec = $ diff- & gt; Format ("% y") * 365 * $ dayLength * 3600 + $ diff- & gt; Format ("% d") * $ dayLength * 3600 + $ diff- & gt; Format ("% H") * 3600 + $ diff- & gt; Format ("% i") * 60 + $ diff- & gt; Format ("% s"); $ Cost = $ lenInSec * $ rate per second; When I try to output cost using $ lenInSec generated from the Deltaime Diff, I actually get weird results. Occasionally, in 1 and 3 out of 1 to 3 times, I get the...

Mysql Local server hardware -

In anticipation of a live scenario, I am creating my entire site, which has a 500 MHz processor with 256 MB A very large 100 MHz RAM I have loaded my database with 200k + rows of garbage data, trying to test my queries. I have seen - obviously because of this, a large display hit all my FAQ using the index, although some 15+ to join (using all indexes) using MySQL To enable 16MB cache, which brings down the query times to nothing but what results? With a dynamic website, I can not see how the cache can help completely when I allow unique queries such as a search feature. I am also using the eaccelerator for PHP. When I use the COUNT (*) total with multiple code JOIN and WHERE , then 10 + There are other queries. Other queries that only get the same line or two do at the same level when I had only a few lines I also noticed that almost 99% of the CPU in CPU CPU stress during a query Comes. Basically I do not know whether the software is on the fault or too much of the h...
