從FTP服務器下載文件到網絡驅動器

我試圖實現一個Windows服務應用程序，它從FTP服務器下載文件並將它們保存到數據庫中指定的網絡驅動器位置。網絡共享文件夾授予完全訪問「所有人」從FTP服務器下載文件到網絡驅動器

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，在這裏我想下載FTP服務器上文件到網絡驅動器。但我得到以下錯誤：

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()

我在這裏失去了一些東西？如何將文件從FTP服務器複製到網絡共享文件夾中？

該服務在哪個帳戶下運行？ –

你是否檢查過每個人都可以訪問文件夾共享和目錄（NTFS權限）？ – Robert

是的，我忘了更改服務進程安裝程序的帳戶類型..謝謝大家 – devphil

通常，您的服務將在僅位於本地主機上的帳戶下運行。因此，它不是從您的網絡上經過身份驗證的帳戶運行的。只需更改該服務正在運行的帳戶，以確保它是來自網絡AD的帳戶，因此它將成爲您所指的所有人組的一部分。
