使用 VB.NET 将文件上传到 FTP 站点

问题描述

我从这个 link 获得了这个工作代码，用于将文件上传到一个 ftp 站点:

I have this working code from this link, to upload a file to an ftp site:

' set up request...
Dim clsRequest As System.Net.FtpWebRequest = _
    DirectCast(System.Net.WebRequest.Create("ftp://ftp.myserver.com/test.txt"), System.Net.FtpWebRequest)
clsRequest.Credentials = New System.Net.NetworkCredential("myusername", "mypassword")
clsRequest.Method = System.Net.WebRequestMethods.Ftp.UploadFile

' read in file...
Dim bFile() As Byte = System.IO.File.ReadAllBytes("C:Temp	est.txt")

' upload file...
Dim clsStream As System.IO.Stream = _
    clsRequest.GetRequestStream()
clsStream.Write(bFile, 0, bFile.Length)
clsStream.Close()
clsStream.Dispose()

不知道，如果ftp目录下已经存在该文件，会不会覆盖该文件?

I wonder, if the file already exists in the ftp directory, the file will be overwritten?

推荐答案

查看MSDN 文档映射到 FTP STOR 命令.查看 FTP STOR 命令的定义，如果用户有权限，它将覆盖现有文件.

Looking at the MSDN documentation this maps to the FTP STOR command. Looking at the definition for the FTP STOR command it will overwrite existing files, if the user has permissions.

所以在这种情况下，是的，文件将被覆盖.

So in this case, yes the file would be overwritten.
