Call API Control DNmonitorSample not match the document

[international4]

The original source code below can not be compiled in V16 server


public DNListener()
: base("DN")
{
SetTypeHandler(
//updated
(x) => Console.WriteLine($"UPDATED {DNInfo(x)}"),
//inserted
(x) => Console.WriteLine($"INSERTED {DNInfo(x)}"),
//deleted
(x) => Console.WriteLine($"DELETED {DNInfo(x)}"),
null, null);
}


than I have to change to :

public DNListener()
: base("DN")
{
SetTypeHandler(
//updated
(x) => Console.WriteLine($"UPDATED {DNInfo(x)}"),
//inserted
(x) => Console.WriteLine($"INSERTED {DNInfo(x)}"),
//deleted
(x,y) => Console.WriteLine($"DELETED {DNInfo(x)}"),
null, null);
}

Then we can compile but we cannot monitor the DN using this function while RegistrationListener can work well.

Please update the source code to be compatible with current 3CX Version.
