Does C# pass a List<T> to a method by reference or as a copy? -

-

इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 4 जवाब

सी # में मेरे पहले कदम उठाते हुए दुनिया सी / सी ++ से है, इसलिए विवरण में थोड़ा धुंधला है। कक्षाएं, जहां तक ​​मुझे समझा जाता था, डिफ़ॉल्ट रूप से संदर्भ से पारित कर दिया जाता है, लेकिन उदाहरण के बारे में सूची के & lt; स्ट्रिंग & gt;

और अन्यत्र 

  शून्य डस्टफ (सूची & lt; स्ट्रिंग & gt; strs) {// स्ट्रिंग की सूची के साथ सामान}  
  सूची से & lt; स्ट्रिंग & gt; Sl = नई सूची & lt; स्ट्रिंग & gt; (); // एक लूप आदि में अगला भरण सूची और उसके साथ सामान करें: डस्टफ (एसएल);  
 
 क्या इस मामले में संदर्भ से पारित किया गया है या एक प्रतिलिपि बनाई गई है जिससे कि मुझे 
 void DoStuff (रेफरी) के रूप में कार्यकर्ता कार्य को फिर से परिभाषित करने की आवश्यकता होगी वास्तव में  स्ल  पर कार्य करने के लिए और कोई प्रतिलिपि नहीं है

इसे संदर्भ से पारित किया गया है सूची & lt; T & gt; एक वर्ग है, और सभी वर्ग के उदाहरण संदर्भ द्वारा पारित किए जाते हैं।

php - proc_open Too many open files in long running Symfony Console app -

-
I have created a console app with a SIM console console component. It was going to run for 5 hours but after running 2 hours I have a proc_open (): Many open files in the pipeline error Symfony \ Component \ Console \ Application.php On-line 985. I tried to gc_collect_cycles in my code, but got the same error. Is this a Symphonic Console component bug or should I not run any app for this long time (but I have to)? This problem relates to: Obviously you have many resources in your app It's not a symphony console bug, but it's a PHP bug. You can modify your program by using another programming language to open fewer files.
