【问题描述】:
我正在尝试通过 ftp 上传文本文件,当我运行程序时,它会清空我的文件然后上传。 我不知道为什么...可能会覆盖或其他...这是我的代码:
这是在主类中
/* Create Object Instance */
ftp ftpClient = new ftp(@"ftp://sportcaffe.me", "sport***", "*****");
/* Upload a File */
ftpClient.upload("public_html/test.txt", @"C:\Users\Lazar\Desktop\test.txt");
这里是ftp类功能代码:
/* Upload File */
public void upload(string remoteFile, string localFile)
{
try
{
/* Create an FTP Request */
ftpRequest = (FtpWebRequest)FtpWebRequest.Create(host + "/" + remoteFile);
/* Log in to the FTP Server with the User Name and Password Provided */
ftpRequest.Credentials = new NetworkCredential(user, pass);
/* When in doubt, use these options */
ftpRequest.UseBinary = true;
ftpRequest.UsePassive = true;
ftpRequest.KeepAlive = true;
/* Specify the Type of FTP Request */
ftpRequest.Method = WebRequestMethods.Ftp.UploadFile;
/* Establish Return Communication with the FTP Server */
ftpStream = ftpRequest.GetRequestStream();
/* Open a File Stream to Read the File for Upload */
FileStream localFileStream = new FileStream(localFile, FileMode.Create);
/* Buffer for the Downloaded Data */
byte[] byteBuffer = new byte[bufferSize];
int bytesSent = localFileStream.Read(byteBuffer, 0, bufferSize);
/* Upload the File by Sending the Buffered Data Until the Transfer is Complete */
try
{
while (bytesSent != 0)
{
ftpStream.Write(byteBuffer, 0, bytesSent);
bytesSent = localFileStream.Read(byteBuffer, 0, bufferSize);
}
}
catch (Exception ex) { MessageBox.Show(ex.ToString()); }
/* Resource Cleanup */
localFileStream.Close();
ftpStream.Close();
ftpRequest = null;
}
catch (Exception ex) { MessageBox.Show(ex.ToString()); }
return;
}
没有错误和警告...
首先我在我的文件中写一些东西并保存,然后当我运行程序时,我的文件是空的,并且那个 empy 文件已经上传了......
