How can I get the assembly file version

In AssemblyInfo there are two assembly versions:

  1. AssemblyVersion: Specify the version of the assembly being attributed.
  2. AssemblyFileVersion: Instructs a compiler to use a specific version number for the Win32 file version resource. The Win32 file version is not required to be the same as the assembly's version number.

I can get the Assembly Version with the following line of code:

Version version = Assembly.GetEntryAssembly().GetName().Version;

But how can I get the Assembly File Version?

version assemblies .net c#

See my comment above asking for clarification on what you really want. Hopefully this is it:

System.Reflection.Assembly assembly = System.Reflection.Assembly.GetExecutingAssembly();
System.Diagnostics.FileVersionInfo fvi = System.Diagnostics.FileVersionInfo.GetVersionInfo(assembly.Location);
string version = fvi.FileVersion;

UPDATE: As mentioned by Richard Grimes in my cited post, @Iain and @Dmitry Lobanov, my answer is right in theory but wrong in practice.

As I should have remembered from countless books, etc., while one sets these properties using the [assembly: XXXAttribute], they get highjacked by the compiler and placed into the VERSIONINFO resource.

For the above reason, you need to use the approach in @Xiaofu's answer as the attributes are stripped after the signal has been extracted from them.

public static string GetProductVersion()
{
  var attribute = (AssemblyVersionAttribute)Assembly
    .GetExecutingAssembly()
    .GetCustomAttributes( typeof(AssemblyVersionAttribute), true )
    .Single();
   return attribute.InformationalVersion;
}

(From http://bytes.com/groups/net/420417-assemblyversionattribute - as noted there, if you're looking for a different attribute, substitute that into the above)
