TPL Dataflow how to remove the link between the blocks

Question

I would like to know. How can I remove the link between the blocks? In other words. I want to get opposite of LinkTo. I want to write a logger based on tlp dataflow. I wrote this interface and want to delete a subscription for ILogListener when it needed. ``` public interface ILogManager { void RemoveListener(ILogListener listener); } ```

Accepted Answer

When you link blocks:

```
var link = someSourceBlock.LinkTo(someTargetBlock);
```

you get a return value that implements `IDisposable`.

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

```
link.Dispose();
```

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

Return Value

Type: System.IDisposable

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