Question

我正在尝试使用C＃.net从谷歌驱动器下载文件。我使用的是https://developers.google.com/drive/web/manage-downloads

中的示例代码

代码无法编译并为IAuthenticator提供定义错误

error CS0234: The type or namespace name 'Authentication' does not exist in the namespace 'Google.Apis' (are you missing an assembly reference?)
error CS0246: The type or namespace name 'IAuthenticator' could not be found (are you missing a using directive or an assembly reference?)

using Google.Apis.Auth.OAuth2;
using Google.Apis.Drive.v2;
using Google.Apis.Drive.v2.Data;
using Google.Apis.Services;
using Google.Apis.Authentication;

public static System.IO.Stream DownloadFile(
  IAuthenticator authenticator, File file) {

我也试过

service.Files.Get(fileId).Download(myFileStream);

然而，这会对“已由进程使用的文件”

给出错误

有没有人成功使用C＃示例下载文件？

PS：我已经安装了必需的nuget pacakages

PM> install-package Google.Apis.Auth

Answer 1

用于SDK的IAuthenticator身份验证器。googleApi中关于IAuthenticator的详细信息并不多，但是您可以将其用于API

        fileID="asd383d8ied2edj82dnc0v";
        Google.Apis.Drive.v2.Data.File file = service.Files.Get(fileId).Execute();
        return  service.HttpClient.GetStreamAsync(file.DownloadUrl).Result;

google drive api download使用.net错误
