Using "My" in C#

[Scott M.]

I've tried following the simple instructions to be able to use MyServices
within C#...Add a project reference to Microsoft.VisualBasic.dll and add:
"using Microsoft.VisualBasic.MyServices;" to the code module. After that, I
expected to be able to use MyClock or MyComputerInfo, but none of the "My"
stuff appears in the intellisense. I've tried rebuilding (after adding the
reference and the using statement) and still no luck.

What am I doing wrong?

The easiest way to find out what the VB code would do is to compile
some VB and then look at it in ILDASM or Reflector.

However, I've seen that certainly you could use the
Microsoft.VisualBasic.Devices namespace and create a new instance of
ComputerInfo, for example.

Ah, I see. The article I was looking at indicated that you need an import
to "MyServices", not "Devices"

Now, it works.

Thanks.

using My = Microsoft.VisualBasic.Devices;

My.Keyboard kb = new My.Keyboard();

for those who like that "My" feel ...

Am I correct in noticing that the one big difference between using the "My"
keyword/namespace in VB .NET and using the classes within the Devices
namespace in C# is that in C#, you must make an instance of the class before
you can use it, while in VB .NET you don't?

I suspect (although I haven't tried it) that the difference is actually
that it's not *clear* that you're creating an instance of the class
before using it in VB - but that it's still doing it under the covers.

The "My" namespace is something that is VB.NET compiler specific and depends
on the (VB) project type, a Web project will have a different "My" namespace
than a Forms project for instance, "My" doesn't really exists outside the VB
IDE, that is C# projects won't see it.
That's also why "My" functionality isn't fully supported from other
languages other than VB, from C# you can refer to the Microsoft.VisualBasic
namespaces like Devices and MyServices and use their classes, but you can't
use the My. syntax.
