问题 I'm not sure if I'm stopping a Parallel.ForEach loop as I intend to do. So let me outline the problem. The loop uses a database driver with limited available connections and it is required to keep track of the open connections, so the database driver doesn't throw an exception. The issue is that keeping track of open connections has been implemented manually (this should be refactored - writing a wrapper or using AutoResetEvent but there are some other things that need to be taken care of

问题 I'm having some trouble using Parallel.ForEach. I need to simulate a couple of hardware components, that wait for an incoming connection, and reply to it. My current code is as follows: Task.Factory.StartNew(() => components, (component) => { var listener = new TcpListener(component.Ip, component.Port); while(true) { using(var socket = listener.AcceptSocket()) { //Read out socket and send a reply socket.Close(); } } }); The problem I'm having is: Not every component will get his own thread

问题 I'm converting an existing application to take advantage of multiple processors. I have some nested loops, and I've converted the inner-most loop into a Parallel.Foreach loop. In the original application, inside the inner-most loop, the code would call DataTable.NewRow() to instantiate a new DataRow of the appropriate layout, populate the columns and add the populated DataRow into the DataTable with DataTable.Add() . But since DataTable is only thread-safe for read operations, I have

问题 Here is the scenario: I have some 'messages' (data) that has to be processed in parallel. In these parallel processes, I would like to log some things in a message specific logfile. I've tried many things, but my logs just get messed up. I've written a small test project.. Let's see the code: using System.Collections.Generic; using System.Threading.Tasks; namespace ParallelTest { public class MessageController { public void InitiateProcesses(List<Message> messagesToProces) { MessageProcessor
