C#将文件上载到Filezilla服务器（XAMPP）错误：无法在传输连接上写入数据

我正在尝试使用FTP将一个文件上传到我的服务器（我用xampp构建了它，所以它有Apache和FileZilla服务器）

一个C#应用程序可以正常工作几个小时，然后我遇到这个异常，应用程序停止上传文件

（我将保持连接的活动状态。代码经过调试并保持一致。我使用xampp在其他机器上进行了一些测试，并遇到了相同的问题。）

这是返回的消息：

System.Net.WebException: Eccezione durante una richiesta WebClient. ---> System.IO.IOException: Impossibile scrivere dati sulla connessione di trasporto: Connessione in corso interrotta forzatamente dall'host remoto. ---> System.Net.Sockets.SocketException: Connessione in corso interrotta forzatamente dall'host remoto

能否将语言设置更改为英语并重新生成错误？此演练还建议检查异常的某些属性：
