如何使用C#在Google Drive v3 API中查找特定文件夹中的文件？

using Google.Apis.Auth.OAuth2;
using Google.Apis.Drive.v3;
using Google.Apis.Services;

// ...

UserCredential credential;
using (var stream = new FileStream("credentials.json", FileMode.Open, FileAccess.Read))
{
    credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
        GoogleClientSecrets.Load(stream).Secrets,
        new[] { DriveService.Scope.Drive },
        "user",
        CancellationToken.None).Result;
}

var service = new DriveService(new BaseClientService.Initializer()
{
    HttpClientInitializer = credential,
    ApplicationName = "Your Application Name",
});

var folderId = "your-folder-id";
var query = $"'{folderId}' in parents";

var request = service.Files.List();
request.Q = query;
request.Fields = "files(id, name)";

var result = request.Execute();
foreach (var file in result.Files)
{
    Console.WriteLine($"File Name: {file.Name}, File ID: {file.Id}");
}
