php - Fatal error: Cannot access parent:: when current class scope has no parent in -

- 

  सार्वजनिक फ़ंक्शन __construct () {मूल :: __ निर्माण (); $ इस- & gt; load- & gt; config ( "मास्टर"); $ इस- & gt; उफ़ (); $ इस- & gt; डेटाबेस (); $ इस- & gt; load- & gt; config ( "लैंग"); $ इस- & gt; load- & gt; मॉडल ( "कार्यों"); }

कोड में क्या गलत है? मुझे पता नहीं क्या गलत है! क्या कोई मेरी सहायता कर सकता है?

मेरे अंग्रेजी के लिए क्षमा करें, मैं जर्मनी से आया हूँ!

< P> मूल :: एक विधि के मूल वर्ग कार्यान्वयन तक पहुंचने के लिए है आपकी कक्षा के पास कोई अभिभावक नहीं है, क्योंकि यह विस्तार नहीं करता है कोई भी वर्ग इसलिए त्रुटि। 

  वर्ग फ़ू {सार्वजनिक फ़ंक्शन बार () {गूंज 'बार'; }} वर्ग बाज़ फू {सार्वजनिक फ़ंक्शन बार ()) को बढ़ाता है (माता पिता :: बार (); गूंज 'बज़'; }}

यहां मूल समझ में आता है, क्योंकि एक अभिभावक वर्ग है। 

  वर्ग फ़ू {सार्वजनिक फ़ंक्शन बार () {मूल :: बार (); }}

यहां मूल कोई मतलब नहीं है, क्योंकि कोई माता पिता नहीं है, इसलिए त्रुटि चूंकि यह कोई मतलब नहीं है और कोई उद्देश्य नहीं है, इसलिए इसे हटा दें।

c# - How to know the number of Threads created and limit the Tasks accordingly -

-
It is very clear that with task as async / await Instead of calling the asynchronous call threads , my question is: Is there a way to monitor threads while completing these tasks? This is because I can decide an optimal number of times for the thread that the thread does not eat too many CPU cycles at the same time (the CPU is intensive to handle the work). We take an example below (output is also mentioned) Although the program is completed in 5 seconds, but it has two threads (id = 1,4 ) if I increase the number of 6 instead of 2, then it creates 4 threads I know that this is the CLR thread OS thread (which is 4 in my machine Are), but I would like to know how they are mapped O (with actions) and use the same CPU. Is there any way to get it? Test code Fixed zero main (string [] args) {RunTasksWithDelays (). ); } Static async Task Run Task with Dislay () {Stopwatch S = Stopwatch. Startup (); Console.light line ("thread id =" + thread.content.trade.manag...
