VB.NET / Visual Studio 2008 - how do i access the REVISION number at run time?

Question

4.00/5 (1 vote)

See more:

I'd simply like to print out the revision number on the main form, so the users could have a way of seeing what version (revision) they are running.

It auto-increments the revision number for me in VS2008, but I can't figure out how to access that same number at runtime.

I've tried...

Dim xversion As String
xversion = My.Application.Info.Version.ToString

and

xversion = System.Windows.Forms.Application.ProductVersion.ToString

and a few other examples I've read online. Seems like this would be easy to grab.

I've also tried setting the AssemblyInfo.vb file code to read

<assembly: xmlns:assembly="#unknown"></assembly:>

Still no luck. This is on a windows forms application... any advice/reply would be appreciated.

Why not using really universal method?

System.Reflection.Assembly.GetEntryAssembly().GetName().Version

' or:

System.Reflection.Assembly.GetExecutingAssembly().GetName().Version

' or any other assembly

We can also try

VB

Public Class Class1
    Dim currentAppVersion = My.Application.Deployment.CurrentVersion
    Dim lastUpdateDate = My.Application.Deployment.TimeOfLastUpdateCheck
End Class

to retrive the version, if the deployment model is 'Click Once'

Solution 1

The My.Application.Info.Version is an object of type

<a href="http://msdn.microsoft.com/en-us/library/system.version.aspx">System.Version</a>[<a href="http://msdn.microsoft.com/en-us/library/system.version.aspx" target="_blank" title="New Window">^</a>]

.

You can get all the version information from that object properties including revision.

can you give me an example of retrieving the revision number in code, into a string?
I have tried using My.Application.Info.Version and My.Application.Info.Version.Revision

The .Version isn't the same revision number as i'm working with when i set it in the project/properties/publish/publish version/revision area (that auto increments). I am expecting (wanting) a .99 and it prints something like .28123

...using code such as this produces that .28123 number:
Dim assem As Assembly = Assembly.GetEntryAssembly()
Dim assemName As AssemblyName = assem.GetName()
Dim ver As Version = assemName.Version
Console.WriteLine("Application {0}, Version {1}", assemName.Name, ver.ToString())

If you are publishing with clickonce you need to use the My.Application.Deployment.CurrentVersion.Revision.

The publish version is not synchronized with the assembly version.
