I know the question was for P12, but Google lead me here when I was looking to do this for the newer, preferred JSON method. I pieced this together with other samples and sites I found. Hope this help save some time.

    public string GetSignedURL()
    {
        var myObj = "theObject";
        var scopes = new string[] { "https://www.googleapis.com/auth/devstorage.read_write" };
        var myBucket = "theBucket";
        ServiceAccountCredential cred;

        using ( var stream = new FileStream(@"\path to\private-key.json", FileMode.Open, FileAccess.Read) )
        {
            cred = GoogleCredential.FromStream(stream)
                                   .CreateScoped(scopes)
                                   .UnderlyingCredential as ServiceAccountCredential;
        }

        var urlSigner = UrlSigner.FromServiceAccountCredential(cred);

        return urlSigner.Sign(myBucket, myObj, TimeSpan.FromHours(1), HttpMethod.Get);
    }
