私人void上传(字符串文件名)

FileInfo fil =新的FileInfo(文件名);

FtpWebRequest requestFTPUploader =(FtpWebRequest)WebRequest.Create(FtpServerName +"/" + FtpFilePath +"/" + fil.Name);

requestFTPUploader.Method = WebRequestMethods.Ftp.UploadFile;

ServicePoint LServicePoint = requestFTPUploader.ServicePoint;
LServicePoint.ConnectionLimit = 1;
requestFTPUploader.Proxy = new WebProxy(){UseDefaultCredentials = true};


FileInfo fileInfo =新的FileInfo(文件名);
FileStream fileStream = fileInfo.OpenRead();

int bufferLength = 2048;
byte []缓冲区=新的byte [bufferLength];

流uploadStream = requestFTPUploader.GetRequestStream();
int contentLength = fileStream.Read(buffer，0，bufferLength);

while(contentLength！= 0)
{
uploadStream.Write(buffer，0，contentLength);
contentLength = fileStream.Read(buffer，0，bufferLength);

Hi frds,

I m using the below code and getting error "The remote server returned an error: (550) File unavailable (e.g., file not found, no access)". Please tell me how to resolve this problem.

private void Upload(string filename)
{
FileInfo fil = new FileInfo(filename);

FtpWebRequest requestFTPUploader = (FtpWebRequest)WebRequest.Create(FtpServerName+"/"+FtpFilePath+"/" + fil.Name);
requestFTPUploader.Credentials = new NetworkCredential(FtpUserId, FtpPassword);
requestFTPUploader.Method = WebRequestMethods.Ftp.UploadFile;

ServicePoint LServicePoint = requestFTPUploader.ServicePoint;
LServicePoint.ConnectionLimit = 1;
requestFTPUploader.Proxy = new WebProxy() { UseDefaultCredentials = true };


FileInfo fileInfo = new FileInfo(filename);
FileStream fileStream = fileInfo.OpenRead();

int bufferLength = 2048;
byte[] buffer = new byte[bufferLength];

Stream uploadStream = requestFTPUploader.GetRequestStream();
int contentLength = fileStream.Read(buffer, 0, bufferLength);

while (contentLength != 0)
{
uploadStream.Write(buffer, 0, contentLength);
contentLength = fileStream.Read(buffer, 0, bufferLength);
}

uploadStream.Close();
fileStream.Close();

requestFTPUploader = null;

}

推荐答案

1)您确定webRequest字符串中没有多余的空格吗?
2)检查以确保您具有写入该服务器的正确特权.

1) Are you sure there is no extra white space in the webRequest string?
2) check to make sure you have the correct privileges to write to that server.
