_TIMESTAMP_ and __TIME__ equivalent in C#

[Eitan]

Hello,

I would like to display a timestamp of when the application was compiled.
In C++ I used the _TIMESTAMP_ and __TIME__ etc.

Do we have anything equivalent in C# and .NET?

Thanks,
EitanB

EitanB,

No, there isn't. The best you could do is get the current assembly and
get the created date, but you can't guarantee that date will be accurate.

Hi,

What would be the way to get the current assembly and the created date?

Thanks

Eitan,

Call the static GetExecutingAssembly method on the Assembly class. From
there, look at the Location or CodeBase properties (depending on where the
assembly was loaded from) which will give you a path. With that path, you
can use a FileInfo instance (or the static methods on the File class) to get
the created date of the file.

Nick,
Why would the date not be accurate? If I do this:

static void Main(string[] args)
{
Assembly assy = Assembly.GetExecutingAssembly();
string path = assy.Location;
DateTime dt = File.GetCreationTime(path);
Console.WriteLine(dt);
Console.ReadLine();
}
}

-- and I do a Rebuild, the Creation date stays the same. Enlighten us!

Nicholas,

Thanks!!

Used LastWriteTime, it gave me the time of the compile (I think....)

Peter,

Creation time is not passed along when the assembly came from an
external website. If the assembly was downloaded from the internet, then
the location will point the location that the file was shadow-copied to, and
the creation time will be the time that it was downloaded, not the time that
the assembly was compiled.

An edge case, yes, but completely possible.

[assembly: AssemblyVersion("1.1.*")]
When specifying a version, you have to at least specify major. If you
specify major and minor, you can specify an asterisk (*) for build. This
will cause build to be equal to the number of days since January 1, 2000
local time, and for revision to be equal to the number of seconds since
midnight local time, divided by 2.

BTW, it's a little confusing to find the version at runtime, you need
Assembly.GetName().Version

While this will work, this is purely an implementation detail. The OP
should be aware of this, and have a backup in the event his app stops
working because that detail changes.

It's part of the public contract for AssemblyVersionAttribute.

However another page says the revision is "random".
