More C# to VB conversion woes when working with Mediator helpers in wpf -


Work through the entire concept of mediated model and use it in wpf, and people who have assisted in this way I

I have been able to follow the logic of my argument and stumbled (but has done nicely) in an article in Sacha Barber on the code project in which he takes the arbitrator, but it Makes a bit more versatile. Almost all your C # examples change well for all times of course! And this is an example of how you actually register for the arbitrator. Those who have not seen this article can refer to it.

The fragment of C #, which causes problems, inside of the example given below,

 < Code> using the system; Using System.Collections.Generic; Using System.ComponentModel; Using System.Linq; Using System.Text; Using System.Windows.Input; Namespace moderator demo {public class reader view model: see modellbase {private string readText = String.Empty; Public Reader Videodel () // // Register for the user to moderator some message mediator. Instruction. Registrar (// Callback Representative, when the message is viewed (object o) = & gt; {ReadText = (string) o;}, View Modell message .UserWroteSomething); } Get public string read text {read  

and teller online converter

  import system Selection. GENERAL IMPORT SYSTEM Component MODEL Importing System Leak imports the system. Text import system View the WinsOnSpace class reader view model inheritanceModelbase private M_Read text, [string] = [string] as the form. Public sub-less New '' User Wright '' For some message 'callback representative, register moderator, when message appears as moderator (string) set m_readText is set m_readText = value (as text) Notification ( "Redtext") And Set End And Property And Class Inform And Namespace  

Then I think it should be hanging on the way to write C # and VB links, take Shall I like it that can not understand it.

I welcome any suggestions.

Many thanks

OK I'm playing something and came up with the following:

  Mediator. Instruction. Registry (Function (By object object) ReadText = DirectCast (O, [String]), see MODEL message. User is fast something)  

The obvious question is, is this correct?

Edit 2

This is the definition of the Registry method, which I think the code is trying to do something but will put some extra light.

  '' '& lt; Summary & gt; '' 'A special message' '' & lt; / Summary & gt; '' '& Lt; Ultimate name = "callback" & gt; To use callback, '' 'When message appears & lt; / Param & gt; '' '& Lt; Param name = "message" & gt; & Lt; / Param & gt; Message to register; Public Sub Register (Callback as Action (of Object), View Message Model Message) Internal List. Code (code, callback) and all  

The code given below is an action (object) There is a valid VB for the parameter.

  Mediation Instruction. Regenerator (reader) as the sub-objects (in the form of objects) TryText = TryCast (O, string), seeModel message, UserWeft something)  

using function in your lambda (o object form corresponds to a object (process) of type type, which may be causing you a type of mismatch problem

inside lambda , If TryCast fails, the string variable ReadText will be set to nothing .

Additionally, remove '[' and ']' from keywords such as object and string , as this syntax system treats symbols. The reason for doing is differently defined as if you want CLR object and string type from there, which I can tell
