Assembly Version Number

In vb6, I could use "App" for displaying the Assembly version number, ie

VB Code:

Me.Caption = Me.Caption & " [V" & App.Major & "." & App.Minor & "." & App.Revision & "]"

Is there a similar way of doing it in .Net? I notice there is a system.version class - but have so far only found it used in the system.Environment namespace (and it isn't the assembly version number).

There best I have found so far is.

VB Code:

Private Function GetAssemblyVersion() As String
      '* Get the Assembly Version of current object *
      Dim strElements() As String
      Dim strName As String
 
      strName = System.Reflection.GetExecutingAssembly.FullName()
      strElements = strName.Split(CType(",", Char))
 
      Return strElements(1)
  End Function

But I kind of expected it to be more readably available...

In an old Beta 1 book i had, i think they used Application insteal of App, Application.Build or something, i dont have it in front of me to be fully sure tho.

If only it were that simple. There is no Application namespace (as far as I can find anyway).

Thanks for the reply anyway.

When i get home tonight, i will look and see what i am using and let you know, i just dont have it infront of me.

thanks

the application object is part of the system.windows.forms namespace

Correction, in VB6 you could get the version number of the Component, executable etc. That's very different from an Assembly.

A process contains AppDomains, and within an AppDomain one or more Assembly get loaded. I wrote a few lines of code to enumerate all the Assemblies within the current AppDomain and get their version numbers:

Assembly[] myAssemblies = AppDomain.CurrentDomain.GetAssemblies();

foreach(Assembly myAssembly in myAssemblies)
{
Console.WriteLine(myAssembly.GetName().Name);
Console.WriteLine(myAssembly.GetName().Version);
Console.WriteLine();
}
Console.ReadLine();

Sorry for the fact that's in C#, personal preference :-)

(And don't forget to implement the Reflection namespace)

Thanks everyone for your help.

You are correct gijsi, in my first question I guess It would have been more accurate if I had used project instead of assembly.

There were two reasons I wanted the version number.

a) to display in the form title bar of the application.

For this I think I can use either:-
System.Windows.Forms.Application.ProductVersion
(thank you Cander and Kleptos for pointing me in the right directiuon for the namespace).

I could also extract from the executing assembly as follows.

VB Code:

Dim oASM As System.Reflection.Assembly
      Dim strVersion as String
 
     oASM = System.Reflection.Assembly.GetExecutingAssembly
     strVersion = oASM.GetName().Version()

Thank you gijsi for helping out with that.

b) I have an error handler that I use to write to the eventlog, and one of the things I wanted to include was to write the version of the application that bombed. To do this when I pass in the exception I also pass the object that caused the exception (ie, me) and I can then use this objject to extract the name and version.
For example,

VB Code:

Public Function ExtractAssemblyVersion(ByVal pvoMe As Object) As Version
      'Extract the Assembly Version of the passed object 
      Dim oAssembly As [Assembly]
      Dim oGetAssembly As [Assembly]
      Dim oVersion As System.Version
      oGetAssembly = oAssembly.GetAssembly(pvoMe.GetType)
      oVersion = oGetAssembly.GetName().Version
      Return oVersion
 
   End Function

Anyway - thanks for the help - it took awhile, but I got there.
