第一步，啟用Drive API

首先，註冊Google帳號；其次，登入Google Developers Console；接著，建立工程和程式；緊接，啟用APIs & auth；最後，選擇Credentials。

第二步，安裝Google Client Library

安裝一個NuGet包（Google.Apis.drive）。如在VS2012上，先選擇Tools，再NuGet Package Manager，接著Package Manager Console。在PM>中輸入Install-Package Google.Apis -Pre,Install-Package Google.Apis.Authentication -Pre,Install-Package Google.Apis.Drive.v2 -Pre。

第三步，編程

 1 using System; 2 using System.Threading; 3 using System.Threading.Tasks; 4  5 using Google; 6 using Google.Apis.Auth.OAuth2; 7 using Google.Apis.Drive.v2; 8 using Google.Apis.Drive.v2.Data; 9 using Google.Apis.Services;10 11 namespace GoogleDriveSamples12 {13     class DriveCommandLineSample14     {15         static void Main(string[] args)16         {17             UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(18                 new ClientSecrets19                 {20                     ClientId = "CLIENT_ID_HERE",21                     ClientSecret = "CLIENT_SECRET_HERE",22                 },23                 new[] { DriveService.Scope.Drive },24                 "user",25                 CancellationToken.None).Result;26 27             // Create the service.28             var service = new DriveService(new BaseClientService.Initializer()29             {30                 HttpClientInitializer = credential,31                 ApplicationName = "Drive API Sample",32             });33 34             File body = new File();35             body.Title = "My document";36             body.Description = "A test document";37             body.MimeType = "text/plain";38 39             byte[] byteArray = System.IO.File.ReadAllBytes("document.txt");40             System.IO.MemoryStream stream = new System.IO.MemoryStream(byteArray);41 42             FilesResource.InsertMediaUpload request = service.Files.Insert(body, stream, "text/plain");43             request.Upload();44 45             File file = request.ResponseBody;46             Console.WriteLine("File id: " + file.Id);47             Console.WriteLine("Press Enter to end this process.");48             Console.ReadLine();49         }50     }51 }

最後，驗證
運行程式後(F5)，跳出APIs申請許可權，點擊“接受”，就運行OK。
