Querying AssemblyInformationalVersionAttribute while targeting Windows Mobile 5.0 PocketPC

Question

I have a version number in my AssemblyInfo.cs file like so:

[assembly: AssemblyInformationalVersion("0.0.0.2")]

Normally I can access this information using FileVersionInfo and I do have a reference to System.dll (where this class is normally defined) but the System.Diagnostics namespace does not seem to be available.

Here's the path that VS says is the System assembly I'm referencing:

C:\Program Files (x86)\Microsoft.NET\SDK\CompactFramework\v3.5\WindowsCE\System.dll

In short: How can I display the version string (AssemblyInformationalVersion) of my application in my application?

Edit: Using

Assembly.GetExecutingAssembly().GetName().Version.ToString()

returns "0.0.0.0" since that attribute is not defined in my AssemblyInfo.cs file.

Answer 1

The solution was to manually enter the following into AssemblyInfo.cs:

[assembly: AssemblyVersion("1.2.3.4")]

I'm not sure why Visual Studio omitted it, but by adding it,

Assembly.GetExecutingAssembly().GetName().Version

returns the expected value.

To sum up: I was using the correct code, but I had the wrong information in my AssemblyInfo.cs file.

Answer 2

So are you trying to get your own app's version:

Debug.WriteLine(string.Format("My App Version: {0}",
    Assembly.GetExecutingAssembly().GetName().Version.ToString()));

or the version of the CF assembly:

Debug.WriteLine(string.Format("System.dll Version: {0}",
    typeof(int).Assembly.GetName().Version.ToString()));

EDIT1

or the actual native FileInfo version (I think this is the one you're after).

EDIT2

Or you could do this for a managed assembly:

var a = Assembly.GetExecutingAssembly().GetCustomAttributes(
    typeof(AssemblyInformationalVersionAttribute), true)
    .FirstOrDefault() as AssemblyInformationalVersionAttribute;
Debug.WriteLine(string.Format("AssemblyInformationalVersion: {0}",
a.InformationalVersion));
