I haven't looked at C # For a long time since I switched to Java in the project, but to be honest, I am in Cao camp. I have long known that. NET4.5 has added async and await, but it has never been used. Today I have seen this article to understand it. I suddenly found that Task is not the concept of Future in Java? The C # code in Jesse Liu's article: static void
This document describes how to use Visual C #. net to create a custom DTS task. You can use C #. net to create custom tasks to extend the data transmission function. After that, you can install and register the task. It shows the DTS design, just like the default DTS task. I
Barrier is an object that prevents individual tasks from continuing until all tasks in the parallel operation reach the appropriate level. This object can be used if the parallel operation is staged in stages and each phase requires synchronization between the tasks. --msdn Private voidbarriertest () {Barrier bar=NewBarrier (4); Task[] Task=Newtask[4]; Action Act= () + ={MessageBox.Show ("Start"); Ba

Today, I use C # as a communication software similar to QQ. Sometimes I don't notice the message, so I want to flash the taskbar after receiving the message, and finally highlight the orange color, it's like sending messages via QQ. After searching and querying the API repeatedly, you need to use this function to find that the taskbar is flashing and staying:Public static extern bool flash1_wex (ref flashwinfo pwfi );The key code for impleme
A job involves the udp communication between c # And c ++ systems. It has not completed the job for a long time, but has encountered many small knowledge points. I have never been familiar with c # And c ++ languages. Everything may be a child, and it will be recorded as a work diary for the time being.
First, solve th
C # Practical Skills: WebApi + Task + WebSocket,I. background
Limitations of the environment:When using the XX client, you must install the print component on each computer. At the same time, because the XX client uses websocket for communication, this requires that the user's Computer Browser must be IE10.0 + or later. This limitation is extremely poor in our company's repository deployment implementation
Speaking of this, still feel very proud (and also thanks to Nick), at least for the moment I do not see the ready-made framework, this thing is mainly used to schedule tasks, is based on time to perform a task, and this task you can write in C # a DLL, The reference to the frame is OK. With the UI interface, I gave it a name called WebWork.
Let's take a look at

C # Multi-Threading automatic management (thread pool)In multi-threaded programs, there are often two situations:1. Application threads spend most of their time waiting, waiting for an event to occur, and then giving a response. This is generally addressed using the ThreadPool (thread pool).2. The line accesses tile is dormant and is only periodically awakened. This is usually solved by using a timer (timer).The ThreadPool class provides a system-main
In C #, a timer is a timer that can execute an event at a specified time interval or at a specified time.The specified time interval refers to the execution of specified events at a specific time interval, such as every 1 minutes, every 10 minutes, and every 1 hours.The specified time is the 30th minute of every hour, daily 10:30:30 (10 points per day, 30 minutes, 30 seconds), etc. to perform the specified event;In both cases, you need to use Timer.in
