I have imported all needed dlls to create service account to access admin features(admin sdk).

But i couldn't find ServiceAccountCredential.

How can i implement this in my project?

Answer 1

ServiceAccountCredential is part of Google.Apis.Auth.OAuth2

Simple example using BigQuery:

using System;
using Google.Apis.Auth.OAuth2;
using System.Security.Cryptography.X509Certificates;
using Google.Apis.Bigquery.v2;
using Google.Apis.Services;

//Install-Package Google.Apis.Bigquery.v2
namespace GoogleBigQueryServiceAccount
{
    class Program
    {

        static void Main(string[] args)
        {

            Console.WriteLine("BigQuery API - Service Account");
            Console.WriteLine("==========================");

            String serviceAccountEmail = "539621478854-imkdv94bgujcom228h3ea33kmkoefhil@developer.gserviceaccount.com";

            var certificate = new X509Certificate2(@"key.p12", "notasecret", X509KeyStorageFlags.Exportable);

            ServiceAccountCredential credential = new ServiceAccountCredential(
               new ServiceAccountCredential.Initializer(serviceAccountEmail)
               {
                   Scopes = new[] { BigqueryService.Scope.DevstorageReadOnly }
               }.FromCertificate(certificate));

            // Create the service.
            var service = new BigqueryService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = "BigQuery API Sample",
            });


        }
    }
}

Here's how you do it in 2017:

• Go to the Service Accounts page

• Create a private key for the service account as a JSON file

• Put the downloaded file in your project (for development) or bake it in your build process

• Reference the Google.Apis.Auth package in your code

    using (var stream = new FileStream("key.json", FileMode.Open, FileAccess.Read))
    {
        var credential = GoogleCredential.FromStream(stream)
                                         .CreateScoped(scopes)
                                         .UnderlyingCredential as ServiceAccountCredential;
  
        //profit
    }
