从FTP服务器下载文件到网络驱动器

我试图实现一个Windows服务应用程序，它从FTP服务器下载文件并将它们保存到数据库中指定的网络驱动器位置。网络共享文件夹授予完全访问“所有人”从FTP服务器下载文件到网络驱动器

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，在这里我想下载FTP服务器上文件到网络驱动器。但我得到以下错误：

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()

我在这里失去了一些东西？如何将文件从FTP服务器复制到网络共享文件夹中？

该服务在哪个帐户下运行？ –

你是否检查过每个人都可以访问文件夹共享和目录（NTFS权限）？ – Robert

是的，我忘了更改服务进程安装程序的帐户类型..谢谢大家 – devphil

通常，您的服务将在仅位于本地主机上的帐户下运行。因此，它不是从您的网络上经过身份验证的帐户运行的。只需更改该服务正在运行的帐户，以确保它是来自网络AD的帐户，因此它将成为您所指的所有人组的一部分。
