我如何从asp.net应用程序接口请求Google Drive访问

using Google.Apis.Auth.OAuth2;
using Google.Apis.Drive.v3;
using Google.Apis.Services;
using Google.Apis.Util.Store;
using System;
using System.IO;
using System.Threading;

public class GoogleDriveService
{
    private static string[] Scopes = { DriveService.Scope.DriveReadonly };
    private static string ApplicationName = "Your Application Name";
    private static string CredentialsFilePath = "Path to your JSON credentials file";

    public static DriveService GetDriveService()
    {
        UserCredential credential;

        using (var stream = new FileStream(CredentialsFilePath, FileMode.Open, FileAccess.Read))
        {
            string credPath = "token.json";
            credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                GoogleClientSecrets.Load(stream).Secrets,
                Scopes,
                "user",
                CancellationToken.None,
                new FileDataStore(credPath, true)).Result;
        }

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

    public static void ListFiles()
    {
        var service = GetDriveService();

        // 请求文件列表
        var request = service.Files.List();
        request.PageSize = 10;
        request.Fields = "nextPageToken, files(id, name)";

        var result = request.Execute();

        // 处理文件列表结果
        if (result.Files != null && result.Files.Count > 0)
        {
            foreach (var file in result.Files)
            {
                Console.WriteLine($"{file.Name} ({file.Id})");
            }
        }
        else
        {
            Console.WriteLine("No files found.");
        }
    }
}
