Create GUID constants? (VB.net)

Public Const ClassId = "92A1377A-7A3C-4FAF-94DA-C229AFFCFB12" Public Const InterfaceId = "2DE393C7-300A-46DB-B33C-583B2765C2F9" Public Const EventsId = "5452FC4D-C0C2-4E2B-87CA-8F43EAA14998"

I found this in a code snippet and need to create my own GUID in vb.net. But I didn't find a way that the program automatically creates constantes like this and shows them in the code. How can I do that? I'm not yet familiar with GUIDs but I suppose there were created automatically.

Thanks for any hints :)

First point is that you cannot apply const modifier to GUID's as const is applied on primitive datatype. If you want you can use Shared ReadOnly.

Second point is you can refer Guid.NewGuid Method () which is used to create GUID. Something like

Dim str = Guid.NewGuid.ToString()

EDIT:

A good MSDN reference which you have found yourself can be helpful.

Firstly you can use GuidGen to create a new unique GUID for you:

Using menu TOOLS -> External Tools... add:
%Installation Path%\Microsoft Visual Studio 14.0\Common7\Tools\guidgen.exe

e.g.

C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools\guidgen.exe

Give it a title of GUID Generator

Then you can run this to create a Guid String for yourself. Select option 4 (Registry Format)

Once you have created a guid, you can assign it to a constant string in your code:

Const MyGuidString = "{1606C5C9-9ECA-4227-9F7E-7FA032D153BE}"

This is however just a string. If you want to use it as an actual Guid, you can define a variable like this:

Dim guidObject = New Guid(MyGuidString)
