getMessages (प्रारंभ, समाप्ति) विधि

P> हो सकता है। लेकिन इस पद्धति को getSortedMessages (सॉर्टटर्म टर्म) विधि के रूप में मापदंडों के रूप में सॉर्ट टर्म नहीं लेते हैं,

भी प्राप्त करेंरेटेड मेसेज विधि पैरामीटर के रूप में श्रेणी संख्याओं को नहीं लेती। < / P>

तो मैं कैसे पृष्ठांकन और दोनों एक साथ छँटाई को लागू कर सकते हैं।

मैं सभी संदेशों को प्राप्त नहीं करना चाहता और फिर उन्हें सॉर्ट करना नहीं चाहता, इससे मेरे आवेदन में खराब प्रदर्शन हो जाएगा।

कोई भी मदद कृपया ...

getMessages विधि और getSortedMessages विधि नहीं है संदेश के लिए डेटा वापस लौटाते हैं, वे केवल सर्वर से संदेश संख्या वापस करते हैं, इसलिए लौटाए गए डेटा की मात्रा बहुत छोटी है। यह तब तक नहीं है जब तक आप लौटा संदेश ऑब्जेक्ट्स का उपयोग करते हुए डाटा तक पहुंच नहीं पाते हैं जो डेटा सर्वर से प्राप्त होता है। आप Folder.fetch विधि का उपयोग करके ओवरहेड को कम करने के लिए थोक में बहुत अधिक डेटा भी पहले से कर सकते हैं।

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...
