System.Threading.Channels 10.0.0-preview.1.25080.5

About

The System.Threading.Channels library provides types for passing data asynchronously between producers and consumers.

Key Features

  • Abstractions representing channels for one or more producers to publish data to one or more consumers
  • APIs focused on asynchronous production and consumption of data
  • Factory methods for producing multiple kinds of channels

How to Use

using System;
using System.Threading.Channels;
using System.Threading.Tasks;

Channel<int> channel = Channel.CreateUnbounded<int>();

Task producer = Task.Run(async () =>
{
    int i = 0;
    while (true)
    {
        channel.Writer.TryWrite(i++);
        await Task.Delay(TimeSpan.FromSeconds(1));
    }
});

Task consumer = Task.Run(async () =>
{
    await foreach (int value in channel.Reader.ReadAllAsync())
    {
        Console.WriteLine(value);
    }
});

await Task.WhenAll(producer, consumer);
