Upload directory of files to FTP server using WebClient(使用 WebClient 将文件目录上传到 FTP 服务器)

本文介绍了使用 WebClient 将文件目录上传到 FTP 服务器的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我已经搜索和搜索，但找不到这样做的方法.我在要上传的目录中有文件.文件名不断变化，所以我无法按文件名上传.这是我尝试过的.

I have searched and searched and cannot find a way to do this. I have files in a directory I want to upload. The file names change constantly so I cannot upload by file name. Here is what I have tried.

using (WebClient client = new WebClient())
{
    client.Credentials = new NetworkCredential("User", "Password");
    foreach (var filePath in files)
        client.UploadFile("ftp://site.net//PICS_CAM1//", "STOR", @"PICS_CAM1");
}


但我得到一个编译器错误:
But I am getting a compiler error:
当前上下文中不存在名称文件"

  The name 'files' does not exist in the current context    
我研究过的一切都表明这应该有效.
Everything I have researched says this should work.  
有没有人可以通过 WebClient 上传文件目录的好方法?
Does anyone have a good way to upload a directory of files via WebClient? 
推荐答案
你必须定义和设置文件.如果您想上传某个本地目录中的所有文件，例如使用 Directory.EnumerateFiles.
You have to define and set the files. If you wanted to upload all files in a certain local directory, use for example Directory.EnumerateFiles.

也是 address 参数noreferrer">WebClient.UploadFile 必须是目标文件的完整 URL，而不仅仅是目标目录的 URL.

Also the address argument of WebClient.UploadFile has to be a full URL to a target file, not just a URL to a target directory.

IEnumerable<string> files = Directory.EnumerateFiles(@"C:localfolder");

using (WebClient client = new WebClient())
{
    client.Credentials = new NetworkCredential("username", "password");

    foreach (string file in files)
    {
        client.UploadFile(
            "ftp://example.com/remote/folder/" + Path.GetFileName(file), file);
    }
}
