Getting the PublicKeyToken of .Net assemblies [duplicate]

What is the simplest way to find the Public-Key-Token of an assembly?

The simplest way I can think of would be a simple right-click, get public key, but this functionality isn't there, maybe there is a Visual Studio Extension for that?

I'm using Visual Studio 2010, if an extension is available.

Open a command prompt and type one of the following lines according to your Visual Studio version and Operating System Architecture :

VS 2008 on 32bit Windows :

"%ProgramFiles%\Microsoft SDKs\Windows\v6.0A\bin\sn.exe" -T <assemblyname>

VS 2008 on 64bit Windows :

"%ProgramFiles(x86)%\Microsoft SDKs\Windows\v6.0A\bin\sn.exe" -T <assemblyname>

VS 2010 on 32bit Windows :

"%ProgramFiles%\Microsoft SDKs\Windows\v7.0A\bin\sn.exe" -T <assemblyname>

VS 2010 on 64bit Windows :

"%ProgramFiles(x86)%\Microsoft SDKs\Windows\v7.0A\bin\sn.exe" -T <assemblyname>

VS 2012 on 32bit Windows :

"%ProgramFiles%\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools\sn.exe" -T <assemblyname>

VS 2012 on 64bit Windows :

"%ProgramFiles(x86)%\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools\sn.exe" -T <assemblyname>

VS 2015 on 64bit Windows :

"%ProgramFiles(x86)%\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools\sn.exe" -T <assemblyname>

Note that for the versions VS2012+, sn.exe application isn't anymore in bin but in a sub-folder. Also, note that for 64bit you need to specify (x86) folder.

If you prefer to use Visual Studio command prompt, just type :

sn -T <assembly> 

where <assemblyname> is a full file path to the assembly you're interested in, surrounded by quotes if it has spaces.

You can add this as an external tool in VS, as shown here:

another option:

if you use PowerShell, you can find out like:

PS C:\Users\Pravat> ([system.reflection.assembly]::loadfile("C:\Program Files (x86)\MySQL\Connector NET 6.6.5\Assemblies\v4.0\MySql.Data.dll")).FullName

like

PS C:\Users\Pravat> ([system.reflection.assembly]::loadfile("dll full path")).FullName

and will appear like

MySql.Data, Version=6.6.5.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d

If the library is included in the VS project, you can check .cproj file, e.g.:

<ItemGroup>
    <Reference Include="Microsoft.Dynamic, Version=1.1.0.20, Culture=neutral, PublicKeyToken=7f709c5b713576e1, processorArchitecture=MSIL">
...

If you have included the assembly in your project, you can do :

            var assemblies =
                AppDomain.CurrentDomain.GetAssemblies();


            foreach (var assem in assemblies)
            {
                    Console.WriteLine(assem.FullName);
            }

You can get this easily via c#

private static string GetPublicKeyTokenFromAssembly(Assembly assembly)
{
    var bytes = assembly.GetName().GetPublicKeyToken();
    if (bytes == null || bytes.Length == 0)
        return "None";

    var publicKeyToken = string.Empty;
    for (int i = 0; i < bytes.GetLength(0); i++)
        publicKeyToken += string.Format("{0:x2}", bytes[i]);

    return publicKeyToken;
}
