cannot declare class directly

Question

Hi

I have a wpf application and a classlibrary project together with it, I have set the namespace name in the properties of the classlibrary, I have also set the namespace name in the actual vb file (in the classlibrary). Then In my xaml.vb file I can Imports xxxx.nameofclasslibrary, but I cannot declare it direct like this...

Dim k As New name.of.my.classlibrary

I can't figure out why, what could be wrong?

Answer 2

In my class I have a public class called Testme, if I add this to my form...

Imports myclass.blablabla.blabla

Then I can access the TestMe Class by this line.

Dim n As New TestMe

But if I remove the Imports part, I cannot do it like this...

Dim n As New myclass.blablabla.blabla.TestMe

Shouldn't I supposed to be able to do that?

Answer 3

Hi again

you need to call it:

Dim n As New blablabla.blabla.TestMe

without the myclass.

Answer 4

In my assembly it look like this....

Namespace MM.Cards.Pdf

    Public Class TestMe

If I remove the Imports part I cannot access TestMe like this...

Dim n As New Cards.Pdf.TestMe

And I cannot access it like this....

Dim n As New MM.Cards.Pdf.TestMe

The only way I can access it is by using the Imports MM.Cards.Pdf

and then declare it like this..

Dim n As New TestMe

Answer 5

Hi again,

in pure VB.NET it works. So if you take a look inside the object browser and search for your class TestMe there you would see exactly where it is and then also how you can call it. I don`t know if this works in a wpf app.

Answer 6

I agree with Heslacher. Object Browser can tell you the "real" namespace of the class. You can also use .NET Reflector to see the namespace.

Also note that VB.NET projects have a root namespace defined in the project property. The namespaces that you specify in code are appended to the root namespace. You propably missed this one.

Hi Jialiang

I have just discovered what caused the problem, in my solution I had a wcf service reference, this service reference was named in this way

MM.ThenameOfmyservicereference

And my class was named....

MM.Cards.Pdf.TestMe

So beacuse they both started with MM. this error ocured. This is a little suprising to me, I thought that as long as the complete name is unique I will be fine, but obviously not.

Answer 9

Hello

I'm glad that you have discovered the problem. You are allowed to use the class by specify its complete name (complete namespace + class name). If you just use the class name, the compiler is not able to decide which class to use under both namespace.
