Getting the date of a .NET assembly

How can I retrieve the Created date from the current .NET assembly?

I'd like to add some realy simple functionality where my app stops working one week after the build date of the main assembly. I already wrote the code that kills my app after a given date. I just need to programmatically retrieve the creation date from the assembly.

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.

What's wrong with:

System.IO.File.GetLastWriteTime(Assembly.GetExecutingAssembly().Location);
user_308740
user_1596990

This should work:

var entryAssembly = Assembly.GetEntryAssembly();
var fileInfo = new FileInfo(entryAssembly.Location);
var buildDate = fileInfo.LastWriteTime;
user_6320

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?
