c# 在 ftping 之前重命名文件

Question

如何在将文件实际传输到服务器之前将文件重命名为时间戳或随机唯一编号？

示例:如果我选择 C:\taco.pdf ..... 1321981871.pdf 实际上是 ftp 到服务器的内容。

FileInfo toUpload = new FileInfo(this.txtFile.Text);

 FtpWebRequest request =
            (FtpWebRequest)WebRequest.Create(
            "ftp://192.168.0.186" + "/" + toUpload.Name
            );

 request.Method = WebRequestMethods.Ftp.UploadFile;

request.Credentials =
            new NetworkCredential("myuser","mypassword");

Stream ftpStream = request.GetRequestStream();
        FileStream file = File.OpenRead(this.txtFile.Text);

 int length = 1024;
        byte[] buffer = new byte[length];
        int bytesRead = 0;


        do
        {
            bytesRead = file.Read(buffer, 0, length);
            ftpStream.Write(buffer, 0, bytesRead);
        }
        while (bytesRead != 0);

 file.Close();
        ftpStream.Close();

如果你只想用不同的名称​​上传文件而不在本地重命名，你就不能改变

 FtpWebRequest request = 
            (FtpWebRequest)WebRequest.Create( 
            "ftp://192.168.0.186" + "/" + toUpload.Name 
            ); 

到

 FtpWebRequest request = 
            (FtpWebRequest)WebRequest.Create( 
            "ftp://192.168.0.186/whatever file name you want");
