TPL Dataflow 如何去除块之间的链接 [英] TPL Dataflow how to remove the link between the blocks

问题描述

我想知道.如何删除块之间的链接?换句话说.我想与 LinkTo 相反.

I would like to know. How can I remove the link between the blocks? In other words. I want to get opposite of LinkTo.

我想写一个基于 tlp 数据流的记录器.

I want to write a logger based on tlp dataflow.

我写了这个接口，想在需要的时候删除对 ILogListener 的订阅.

I wrote this interface and want to delete a subscription for ILogListener when it needed.

public interface ILogManager
{
    void RemoveListener(ILogListener listener);
}

推荐答案

链接块时:

var link = someSourceBlock.LinkTo(someTargetBlock);

你得到一个实现 IDisposable 的返回值.

you get a return value that implements IDisposable.

要终止链接，只需处理该返回值:

To kill the link, just dispose of that return value:

link.Dispose();

请参阅.LinkTo 文档(特别是关于 return 语句的部分):

See the .LinkTo documentation (in particular the section about the return statement):

返回值

类型:System.IDisposable

Type: System.IDisposable

一个 IDisposable，在调用 Dispose 时，将取消源与目标的链接.

An IDisposable that, upon calling Dispose, will unlink the source from the target.
