您不能按照Google的建议使用“服务帐户密钥JSON文件”。

需要使用p.12证书文件进行身份验证。

创建用于模拟帐户的驱动器服务的代码如下所示。

public DriveService GetService(string certificatePath, string certificatePassword, string googleAppsEmailAccount, string emailAccountToMimic, bool allowWrite = true)
{
    var certificate = new X509Certificate2(certificatePath, certificatePassword, X509KeyStorageFlags.Exportable);

    var credential = new ServiceAccountCredential(
       new ServiceAccountCredential.Initializer(googleAppsEmailAccount)
       {
           Scopes = new[] { allowWrite ? DriveService.Scope.Drive : DriveService.Scope.DriveReadonly },
           User = emailAccountToMimic
       }.FromCertificate(certificate));

    // Create the service.
    return new DriveService(new BaseClientService.Initializer
    {
        HttpClientInitializer = credential,
        ApplicationName = ApplicationName
    });
}

您需要按照此处列出的步骤将域范围的权限委托给服务帐户。
