问如何使用C#从谷歌云中的特定文件夹读取文件

EN

string bucketName = "testbucket";

// Explicitly use service account credentials by specifying the private key file.
// The service account should have Object Manage permissions for the bucket.
GoogleCredential credential = null;
using (var jsonStream = new FileStream("credentials.json", FileMode.Open,
    FileAccess.Read, FileShare.Read))
{
    credential = GoogleCredential.FromStream(jsonStream);
}
var storageClient = StorageClient.Create(credential);

// List objects
foreach (var obj in storageClient.ListObjects(bucketName, ""))
{
    //Console.WriteLine(obj.Name);
    var fileStream = File.Create("Program-copy.xml");
    storageClient.DownloadObject(bucketName, obj.Name, fileStream);
    break;
}
