asynchronous c#

Opening I because of the love of network programming, regular use of C # to write various types of servers (e.g TCP server, UDP server), but basically are engaged in play, there are a lot of web-based C # network programming articles, of course, I also refer to a lot of authors write articles. After reading this article will not be exported to find information. This series of articles introduces

C-Ares is an asynchronous DNS request library. libcurl, libevent, and Wireshark all use C-Ares. Before gevent1.0, libevent is used, Therefore, its DNS request uses C-Ares, and later versions use cython to encapsulate C-Ares. C-Are

C # Threading Knowledge-using ThreadPool to perform asynchronous operationsThere are many complex tasks in your application that may require collaboration with one or more worker threads or I/O threads, such as timed tasks, database data operations, Web services, file processing, and so on. These tasks can be time consuming, and in order for the user interface to respond in a timely manner, an additional th

Objective Because the undergraduate graduation design to do a distributed file system, one of the modules need to implement file IO. To verify my understanding of asynchronous Io, I decided to build the wheel of an asynchronous file IO. The operating system has given a variety of asynchronous operation of the API, such as overlapping IO, iocp,kqueue,sele

C #~ Asynchronous programming continues ~ W3wp.exe caused by awaitand asynccrashes, This has recently started to happen again. The application pool of IIS is not suspended and all points to the same finger, async, threadPool, Task, and System. nullReferenceException makes us feel that our asynchronous program has a problem. The same is true. Our

a reference to the IAsyncResult interface of the asynchronous method that just ended, remember that the IAsyncResult interface object is inside the AsyncResult class object.2) Although the IAsyncResult interface does not have a reference to a delegate object, the AsyncResult class object that contains it has a reference to the delegate object.3) with a reference to the class object, we can now invoke the AsyncDelegate property of the class object and

Asynchronous client socket example The following example creates a client to connect to the server. The client is generated using an asynchronous socket, so the execution of the client application is not suspended when the server returns a response. The application sends the string to the server and then displays the string returned by the server on the console. C
