Getting the date of a .NET assembly [duplicate]

Answer 1

The best way to do this would be with a custom attribute that you set on the PreBuild of your assembly.

And then use the standard reflection to get the attribute you created.

But out of curiosity, why kill the app after the BUILD date?

Answer 2

This should work:

var entryAssembly = Assembly.GetEntryAssembly();
var fileInfo = new FileInfo(entryAssembly.Location);
var buildDate = fileInfo.LastWriteTime;

Answer 3

What's wrong with:

System.IO.File.GetLastWriteTime(Assembly.GetExecutingAssembly().Location);

Answer 4

I don't think the assembly itself contains it's creation date. I suspect the closest you can get is the creation date of the assembly file itself:

File.GetCreationTime(Assembly.GetExecutingAssembly().Location)

should do the trick.

EDIT:

I think Jeff Atwood's solution, written up by "grenade" in this thread, is probably the better way to go now.

Answer 5

Maybe this post on coding horror may help

Answer 6

If you're writing an application for a mobile device using the compact framwork, Assembly.Location is not available.

Here, I found an alternative:

     System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase)
