Keyword this not available in the current context

[Guest]

Hi

I'm trying to use Rockford Lhotka's "Implementing a Background Process in Visual Basic .NET" in C#" http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnadvnet/html/vbnet09272002.asp.

I have added the Background project in my solution as a VB Project. My UI is in C#. When I try to compile it I get an error saying that "Keyword this is not available in the current context." The line that it errors on is this:

public class Form1 : System.Windows.Forms.Form, IClient
{

------> private Controller m_controller = new Controller(this);

where the constructor for Controller takes a reference to the Client Interface. My Form class inherits from the System.Windows.Forms.Form class and Implements the IClient interface. In VB.NET I do not get this error when I try the following line:

Public Class Form1
Inherits System.Windows.Forms.Form
Implements IClient

Private mController As New Controller(Me)


Can you please tell me how to get this to work in C#.

Thanks

Amit

Try moving the assignment of the mController into the constructor.

public class Form1 : Form, IClient
{
private Controller mController;

public Form1()
{
mController=new Controller(this);
}

......

}

Doh! That worked. Thanks for your help.

public class Form1 : Form, IClient

private Controller mController;

public Form1()
