此方法将做到这一点：

        var server = new HttpServer(configuration);
        var invoker = new HttpMessageInvoker(server);
        var certificate = GetCertificate();

        var request = new HttpRequestMessage(HttpMethod.Get, "http://localhost/YourPath");
        request.Properties[HttpPropertyKeys.ClientCertificateKey] = certificate;
        var result = await invoker.SendAsync(request, CancellationToken.None);
