Question

我在我的asp.net应用程序中使用此方法将上传文件从本地目录传输到azure存储。我现在想用FTP文件夹中的文件做同样的事情。我调查了FtpWebRequest，但不确定它是如何以及是否适用于当前的方法？

foreach (string strFile in Directory.GetFiles("myftpsite", "*.jpg"))
{
    blob = blobContainer.GetBlobReference(strFile);
    blob.UploadFile(strFile);                
}

Answer 1

要列出FTP文件夹中的所有文件，请参阅：http://msdn.microsoft.com/en-us/library/ms229716.aspx

我不知道如何直接阅读它们，所以我会将它们下载到本地机器并将它们上传到您需要的地方。
