谷歌云端硬盘API下载使用.NET错误

本文关键字：NET 错误 下载 云端 硬盘 API 谷歌 | 更新日期: 2023-09-27 18:30:22

我正在尝试使用C# .net从Google云端硬盘下载文件。我正在使用 https://developers.google.com/drive/web/manage-downloads 中的示例代码

代码无法编译并给出 IAuthenticator 的定义错误 

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);

但是，这会在"进程已使用的文件"上给出错误

有没有人成功使用 C# 示例下载文件？

PS：我已经安装了所需的nuget pacakages。

用于

SDK的IAuthenticator身份验证器。谷歌 API 中没有太多关于 IAuthenticator 的详细信息，但您可以用于 API

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