使用WebClient将文件目录上载到FTP服务器 [英] Upload directory of files to FTP server using WebClient

问题描述

我已经搜索了，但找不到解决方法。我在要上传的目录中有文件。文件名不断变化，因此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\");
}

但是我遇到了编译器错误：

But I am getting a compiler error:

在当前上下文中不存在文件名

The name 'files' does not exist in the current context

一切我研究说这应该工作。

Everything I have researched says this should work.

有人可以通过 WebClient 上传文件目录吗？

Does anyone have a good way to upload a directory of files via WebClient?

推荐答案

您必须定义并设置文件。如果要上载某个本地目录中的所有文件，请使用例如 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.

地址 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:\local\folder");

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);
    }
}
