You would think it’s simple enough to get the file version information as it is set in Visual Studio’s UI setting, but it wasn’t for me.  Even after Googling around I only discovered how to the the Assembly version, not the file version.  Well not until I found this article. The information is at the end of it and it basically goes like this:

string fileVersion = FileVersionInfo
       .GetVersionInfo(Assembly.GetExecutingAssembly().Location).FileVersion;

I then also wanted to get the date too.  This is how I did it:

string fileDate = System.IO.File
       .GetCreationTime(Assembly.GetExecutingAssembly().Location)
       .ToString("MMMM dd, yyyy")

FileVersionInfo is at System.Diagnostics
Assembly is at System.Reflection

The best thing is I no longer have to remember to set this stuff before packaging up my app for shipment.  Like I am doing right now:  BD File Hash version 1.0.10 going out right now.
