Assembly version from command line?

If you use mono and linux, try this:

monodis --assembly MyAssembly.dll

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

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.

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()
