Assembly version from command line?

Is there a Microsoft tool to get the assembly version of a DLL file from a command line?

(I know that I can code my own tool.)

This is an area where PowerShell shines. If you don't already have it, install it. It's preinstalled with Windows 7.

Running this command line:

[System.Reflection.Assembly]::LoadFrom("C:\full\path\to\YourDllName.dll").GetName().Version

outputs this:

Major  Minor  Build  Revision
-----  -----  -----  --------
3      0      8      0

Note that LoadFrom returns an assembly object, so you can do pretty much anything you like. No need to write a program.

If you use mono and linux, try this:

monodis --assembly MyAssembly.dll

find . -name MyAssembly.dll -exec monodis --assembly {} ';' | grep Version 

For those, like I, who come looking for such a tool:

using System;
using System.IO;
using System.Reflection;

class Program
{
    public static void Main(string[] args)
    {
        foreach (string arg in args)
        {
            try
            {
                string path = Path.GetFullPath(arg);
                var assembly = Assembly.LoadFile(path);
                Console.Out.WriteLine(assembly.GetName().FullName);
            }
            catch (Exception exception)
            {
                Console.Out.WriteLine(string.Format("{0}: {1}", arg, exception.Message));
            }
        }
    }
}

In Powershell

$version = [System.Diagnostics.FileVersionInfo]::GetVersionInfo("filepath.exe").FileVersion.ToString()

I used the selected answer until I got the following error Reference assemblies should not be loaded for execution. They can only be loaded in the Reflection-only loader context. for several assemblies

using

[System.Reflection.Assembly]::ReflectionOnlyLoadFrom("C:\full\path\to\YourDllName.dll").GetName().Version

should work in those cases (probably all cases)

Wow this is bad considering things like old exploitable gdiplus.dll's floating around.

My solution is simple. batch file programming.

This puts an nfo file in the same dir with the version

You can GET filever.exe, which can be downloaded as part of the Windows XP SP2 Support Tools package - only 4.7MB of download.

adobe_air_version.bat

c:\z\filever.exe /A /D /B "C:\Program Files\Common Files\Adobe AIR\Versions\1.0\Adobe AIR.dll" >000_adobe_air.dll_VERSION.nfo

exit

Variation.

Get all the versions in a directory to a text file.

c:\z\filever.exe /A /D /B "c:\somedirectory\ *.dll *.exe >000_file_versions.nfo

exit

There's also Sigcheck by systernals.

File Version tool will help:

filever /V YourDllName.dll

Adding some sugar to the other powershell-ish answers...

To get extended properties like 'FullName'

$dllPath = "C:\full\path\to\YourDllName.dll";
$ass  = [System.Reflection.Assembly]::LoadFrom($dllPath);
$ass.GetName();
$ass

Do you use GACUTIL?

You can get the assembly version from this command below.

C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\gacutil.exe /L "<your assembly name>"
