向FTP服务器下载文件的简单实例
string filePath = "d:\\";
string fileName = "lhking.txt"; //文件下载之后要保存的路径和文件名
FtpWebRequest reqFTP;
try
{
FileStream outputStream = new FileStream(filePath +"\\" + fileName, FileMode.Create);
string filename = "ip.txt";
string ftpServerIP = "222.76.217.24";
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" +ftpServerIP + "/" + filename));
reqFTP.Method = WebRequestMethods.Ftp.DownloadFile;
reqFTP.UseBinary = true;
reqFTP.Credentials = new NetworkCredential("l","l");
FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
Stream ftpStream = response.GetResponseStream();
long cl = response.ContentLength;
int bufferSize = 2048;
int readCount;
byte[] buffer = new byte[bufferSize];
readCount = ftpStream.Read(buffer, 0, bufferSize);
while (readCount > 0)
{
outputStream.Write(buffer, 0, readCount);
readCount = ftpStream.Read(buffer, 0, bufferSize);
}
ftpStream.Close();
outputStream.Close();
response.Close();
