C# ClassLibrary External Interface

[Tom Roach]

Need to create first simple C# ClassLibrary with string property accessible
from VB 6.0 application. Have .NET-created, regasm-registered, and
VB-accessed a prototype --> VB can "see" the property via ObjectBrowser but
can't use it. Other than adding the "public interface" statement and then
adding Properties to it (see below), can someone outline what other steps
are needed?

Thanks for your help!


using System;



namespace CsharpEmailer

{

/// <summary>

/// Summary description for Class1.

/// </summary>

public class Class1

{

public Class1()

{

//

// TODO: Add constructor logic here

//

}

public interface emailer

{



string EmailAttachmentInputString

{

get;

set;

}

}

}

}

It would appear the interface is a member of the class as opposed to
namespace.

Also, while not absolutely necessary, you really should use attributes
to control what is exposed to COM.

Look at the ComVisible, ProgId, Guid and InterfaceType attributes.
