.NET分派器，用于.NET Core？ [英] .NET Dispatcher, for .NET Core?

问题描述

.NET Core是否存在类似 Dispatcher 的东西？

Does something like Dispatcher exist for .NET Core?

我需要在.NET中创建一个线程核心，并能够发送要在线程上调用的动作。另外，我希望能够使用 TaskScheduler 可以用于 async / await 的东西。

I need to create a thread in .NET Core, and be able to send actions to be invoked on the thread. Also, I'd like to be able to use a TaskScheduler that can be used for async/await stuff.

这是否存在？

推荐答案

它不是内置的，但是我的 AsyncContext 和 AsyncContextThread 类型在满足您需求的库中可用。

It's not built-in, but my AsyncContext and AsyncContextThread types are available in a library that would fit your need.

AsyncContext 接管当前线程：

AsyncContext.Run(async () =>
{
  ... // any awaits in here resume on the same thread.
});
// `Run` blocks until all async work is done.

AsyncContextThread 是具有自己的独立线程 AsyncContext ：

AsyncContextThread is a separate thread with its own AsyncContext:

using (var thread = new AsyncContextThread())
{
  // Queue work to the thread.
  thread.Factory.Run(async () =>
  {
    ... // any awaits in here resume on the same thread.
  });
  await thread.JoinAsync(); // or `thread.Join();`
}

AsyncContext 提供 SynchronizationContext 以及 TaskScheduler / TaskFactory 。
