我正在尝试实现一个 Windows 服务应用程序，该应用程序从 FTP 服务器下载文件并将它们保存到 DB 中指定的网络驱动器位置。网络共享文件夹授予“所有人”的完全访问权限

bool status = true;
string webError = string.Empty;
FtpWebResponse response = null;
Stream ftpStream = null;
FileStream outputStream = null;
FtpDownloadToFolder = @"\\servername\SharedFolder\";
fileName  = "test.jpg";

FtpWebRequest reqFTP = WebRequest.Create(new Uri(FtpAddress + "/" + fileName)) as FtpWebRequest;
reqFTP.Credentials = new NetworkCredential(FtpUser, FtpPassword);
reqFTP.Method = WebRequestMethods.Ftp.DownloadFile;
reqFTP.UseBinary = true;
reqFTP.Timeout = FtpTimeout;
response = reqFTP.GetResponse() as FtpWebResponse;
ftpStream = response.GetResponseStream();

if (!FtpDownloadToFolder.EndsWith("\\"))
{
    FtpDownloadToFolder = FtpDownloadToFolder + "\\";
}
outputStream = new FileStream(FtpDownloadToFolder + "/" + fileName, FileMode.Create);

long cl = response.ContentLength;
int bufferSize = 2048;
byte[] buffer = new byte[bufferSize];
int readCount = ftpStream.Read(buffer, 0, bufferSize);

while (readCount > 0)
{
    outputStream.Write(buffer, 0, readCount);
    readCount = ftpStream.Read(buffer, 0, bufferSize);
}

所以，我在这里尝试将文件从 FTP 服务器下载到网络驱动器中。但我收到以下错误：

Access to the path '\\servername\SharedFolder\test.jpg' is denied.

System.Net.WebException: The remote server returned an error: 150 0.066 seconds (measured here), 3.78 Mbytes per second

   at System.Net.FtpDataStream.Dispose(Boolean disposing)
   at System.IO.Stream.Close()
   at System.Net.FtpWebResponse.Close()

我在这里错过了什么吗？如何将文件从 FTP 服务器复制到网络共享文件夹？

通常，您的服务将在仅在本地主机上的帐户下运行。因此，它不是从您网络上经过身份验证的帐户运行的。只需更改运行服务的帐户，以确保它是来自您的网络 AD 的帐户，因此它将成为您所指的 Everyone 组的一部分。
