上传后如何重命名文件 [英] How to rename a file after upload

问题描述

我可以上传，但不知道如何重新命名它。
$ b

代码如下所示：

  FtpWebRequest requestFTP =（FtpWebRequest ）FtpWebRequest.Create（新的Uri（ftp：//+ ftpServer +/+httpdocs / webroot /+ destination +/+ fileName））; 
 requestFTP.Proxy = null; 
 
 requestFTP.Credentials = new NetworkCredential（ftpUser，ftpPassword）; 
 requestFTP.Method = WebRequestMethods.Ftp.UploadFile; 
 FileStream fStream = fileInfo.OpenRead（）; 
 int bufferLength = 2048; 
 byte [] buffer = new byte [bufferLength]; 
流uploadStream = requestFTP.GetRequestStream（）; 
 int contentLength = fStream.Read（buffer，0，bufferLength）; 
 while（contentLength！= 0）
 {
 uploadStream.Write（buffer，0，contentLength）; 
 contentLength = fStream.Read（buffer，0，bufferLength）; 
} 
 uploadStream.Close（）; 
 fStream.Close（）; 
 
 requestFTP = null; 
 
 string newFilename = fileName.Replace（。ftp，）; 
 requestFTP.Method = WebRequestMethods.Ftp.Rename; //这样做会造成问题
 requestFTP.RenameTo（newFilename）; 
  

我得到的错误是

错误2不可使用的成员'System.Net.FtpWebRequest.RenameTo'
不能像方法一样使用。

解决方案

RenameTo是一个属性，而不是一个方法。你的代码应该是这样的：

$ $ p $ $ $ $ $ $ $ $ $ $ $ requestFTP =（FtpWebRequest） FtpWebRequest.Create（新的Uri（ftp：//+ ftpServer +/+httpdocs / webroot /+ destination +/+ fileName））;
requestFTP.Proxy = null;
requestFTP.Credentials = new NetworkCredential（ftpUser，ftpPassword）;

string newFilename = fileName.Replace（。ftp，）;
requestFTP.Method = WebRequestMethods.Ftp.Rename;
requestFTP.RenameTo = newFilename;
requestFTP.GetResponse（）;

I have to upload file using Ftp protocol on server, and rename uploaded file after uploading.

I can upload it, but don't know how to rename it.

Code looks like this:

FtpWebRequest requestFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpServer + "/" + "httpdocs/webroot/" + destination + "/" + fileName));
requestFTP.Proxy = null;

requestFTP.Credentials = new NetworkCredential(ftpUser, ftpPassword);
requestFTP.Method = WebRequestMethods.Ftp.UploadFile;
FileStream fStream = fileInfo.OpenRead();
int bufferLength = 2048;
byte[] buffer = new byte[bufferLength];
Stream uploadStream = requestFTP.GetRequestStream();
int contentLength = fStream.Read(buffer, 0, bufferLength);
while (contentLength != 0)
{
  uploadStream.Write(buffer, 0, contentLength);
  contentLength = fStream.Read(buffer, 0, bufferLength);
}
uploadStream.Close();
fStream.Close();

requestFTP = null;

string newFilename = fileName.Replace(".ftp", "");
requestFTP.Method = WebRequestMethods.Ftp.Rename; // this like makes a problem
requestFTP.RenameTo(newFilename);

Error I'm getting is

Error 2 Non-invocable member 'System.Net.FtpWebRequest.RenameTo' cannot be used like a method.

解决方案

RenameTo is a property, not a method. Your code should read:

// requestFTP has been set to null in the previous line
requestFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + ftpServer + "/" + "httpdocs/webroot/" + destination + "/" + fileName));
requestFTP.Proxy = null;
requestFTP.Credentials = new NetworkCredential(ftpUser, ftpPassword);

string newFilename = fileName.Replace(".ftp", "");
requestFTP.Method = WebRequestMethods.Ftp.Rename;
requestFTP.RenameTo = newFilename;
requestFTP.GetResponse();
