Учетная запись службы Google drive

---

Как просмотреть файлы, загруженные в учетную запись службы Google Drive, из ASP.NET веб-приложение ? Я использовал Google Drive API v3 и предоставил здесь код, который я использовал для загрузки файлов. Пожалуйста, помогите мне в этом. Спасибо!

Что я уже пробовал:

using System;
using Google.Apis.Drive.v3;
using Google.Apis.Auth.OAuth2;
using System.Threading;
using Google.Apis.Util.Store;
using Google.Apis.Services;
using Google.Apis.Drive.v3.Data;
using System.Collections.Generic;
using System.Security.Cryptography.X509Certificates;
using System.Web.UI;

namespace Sample
{
public partial class testing : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}
private static string GetMimeType(string fileName)
{
string mimeType = "application/unknown";
string ext = System.IO.Path.GetExtension(fileName).ToLower();
Microsoft.Win32.RegistryKey regKey = Microsoft.Win32.Registry.ClassesRoot.OpenSubKey(ext);
if (regKey != null && regKey.GetValue("Content Type") != null)
    mimeType = regKey.GetValue("Content Type").ToString();
return mimeType;
}
protected void Button2_Click(object sender, EventArgs e)
{
connect();
}
public void connect()
{
string[] scopes = new string[] { DriveService.Scope.Drive }; // Full access

var keyFilePath = @"D:\kk\****46bb0790d147.p12";    // Downloaded from https://console.developers.google.com
var serviceAccountEmail = "k******.iam.gserviceaccount.com";  // found https://console.developers.google.com

//loading the Key file
var certificate = new X509Certificate2(keyFilePath, "notasecret", X509KeyStorageFlags.Exportable);
var credential = new ServiceAccountCredential(new ServiceAccountCredential.Initializer(serviceAccountEmail)
{
    Scopes = scopes
}.FromCertificate(certificate));

/////////////////////////
var service = new DriveService(new BaseClientService.Initializer()
{
    HttpClientInitializer = credential,
    ApplicationName = "Drive API Sample",
});
/////////////////////////
if (System.IO.File.Exists(@"C:\Project\Uploads\Eidea.txt"))
{
    File body = new File();
    body.Name = System.IO.Path.GetFileName(@"C:\Project\Uploads\Eidea.txt");
    body.Description = "File uploaded";
    body.MimeType = GetMimeType(@"C:\Project\Uploads\Eidea.txt");

    // File's content.
    byte[] byteArray = System.IO.File.ReadAllBytes(@"C:\Project\Uploads\Eidea.txt");
    System.IO.MemoryStream stream = new System.IO.MemoryStream(byteArray);
    try
    {
        FilesResource.CreateMediaUpload request = service.Files.Create(body, stream, GetMimeType(@"C:\Project\Uploads\Eidea.txt"));
         request.Upload();
     //  Console.WriteLine(request.ResponseBody);
        ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "alertMessage", "alert('" + request.ResponseBody + "')", true);
    }
    catch (Exception e)
    {
        Console.WriteLine("An error occurred: " + e.Message);
    }

}
}
}
    }
