how to find out the version of an assembly?

I need to extract the version number of an assembly in my .NET Windows app.
The assembly is not referenced by this Windows app. I think I need to use
reflection but just can't figure out the coding. Could someone help?

Thanks a lot in advance
Bob

Quoting from some answers from other people in these forums:

The GetName method on the Assembly will give you an instance of the
AssemblyName class. That will have a Version property which will return an
Version class instance. Once you have this, you should be able to use the
properties of the class (Build, Major, Minor, Revision) or you can get a
string representation by calling ToString.

And:

************
Code Sample
************
try
{
Assembly a = Assembly.LoadFrom("FTPClient.dll");
Console.WriteLine("Image Runtime Version: {0}", a.FullName);
Debug.WriteLine("Image Runtime Version: " + a.FullName);
}
catch (Exception e)
{
Console.WriteLine("Exception occurred: {0}", e.Message);
}
finally
{
Console.ReadLine();
}

************
Output
************
Image Runtime Version: FTPClient, Version=1.0.1117.28417, Culture=neutral,
PublicKeyToken=null

Hope that gives you something to work with. Anyway, good luck!

If you know the name and location of the assembly, you can also use
the FileVersionInfo class. The benefit is the fact you don't have to
actually LOAD the assembly to get at its file and product version info
(this is especially important since you can't UNLOAD an assembly per
se).
