推荐答案

我和连接谷歌驱动器与我的应用程序相同的问题，但现在我发现了一个解决方案，它绝对是工作对我罚款。谷歌客户端的lib将处理所有的you.Download的NuGet包Google.GData.Client和Google.GData.Documents。

I had Same Problem with connecting Google Drive with my Application, but now I found one solution which absolutely Working fine for me. Googles Client lib will handle all that for you.Download nuget Package Google.GData.Client and Google.GData.Documents.

下面我code

 parameters = new OAuth2Parameters()
                {
                    ClientId = "CLIENT_ID",
                    ClientSecret = "CLIENT_SECRET",
                    RedirectUri = currentURL,//"http://localhost:6600/Home.html",
                    Scope = "https://docs.google.com/feeds/ ",
                    State = "documents",
                    AccessType = "offline",  // offline means it creats a refreshtoken 
                    TokenExpiry = DateTime.Now.AddYears(1)
                };
                string url = Google.GData.Client.OAuthUtil.CreateOAuth2AuthorizationUrl(parameters);

1），在这里用户应与他的帐户登录，从而使这里重定向页面 2）当你回到你的页面（的Oauth重定向页） 3）再从URL code和状态（查询字符串） 4）发送到服务器（页面加载事件） 5）写以下code Page_Load事件（首次得到code变量中的查询字符串）

1) here user should login with his account so redirect your page here 2) when you came back to your page (Oauth Redirect Page) 3) then take code and state from url(QueryString) 4) send to server (page load event) 5) write following code page_load event(first get query string in code variable)

 OAuth2Parameters parameters = new OAuth2Parameters()
            {
                ClientId = "274488228041-1aaq8a069h3c7lsjstsl394725tumdlo.apps.googleusercontent.com",
                ClientSecret = "Ew1EMwe4EB8oLHvKFfDZxQhp",
                RedirectUri = currentURL,//"http://localhost:6600/Home.html"
                Scope = "https://docs.google.com/feeds/ ",
                State = "documents",
                AccessType = "offline",   // offline means it creats a refreshtoken 
                TokenExpiry = DateTime.Now.AddYears(1)
            };
            parameters.AccessCode = code;

            Google.GData.Client.OAuthUtil.GetAccessToken(parameters);

1），在这里，你会得到accesstoken和requesttoken 2）保存在数据库中供日后用途（离线访问） 3）传递参数来访问谷歌驱动器文件

1) here you will get accesstoken and requesttoken 2) save it in Database for future purpose(offline access) 3) pass parameters to access Google Drive Documents

   GOAuth2RequestFactory requestFactory = new GOAuth2RequestFactory(null, "Infactum", parameters);
            DocumentsService service = new DocumentsService("Infactum");
            service.RequestFactory = requestFactory;
            //requestFactory.CustomHeaders["Authorization"] = "Bearer " + parameters.AccessToken;
            DocumentsListQuery query = new DocumentsListQuery();
            query.NumberToRetrieve = 2000;

            // Make a request to the API and get all documents.
            DocumentsFeed feed = service.Query(query);

在这里，你会得到所有类型的饲料对象，你可以访问使用feed.entries文件2000文件...希望你喜欢它

here, You will get all types of 2000 files in feed object you can access files using feed.entries... hope you like it
