提问by user1361207
I am trying to use the ftpWebRequest in c# my code is
我正在尝试在 c# 中使用 ftpWebRequest 我的代码是
// Get the object used to communicate with the server.
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://192.168.20.10/file.txt");
request.Method = WebRequestMethods.Ftp.UploadFile;
// This example assumes the FTP site uses anonymous logon.
request.Credentials = new NetworkCredential("dev\ftp", "devftp");
// Copy the contents of the file to the request stream.
StreamReader sourceStream = new StreamReader(@"\file.txt");
byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
sourceStream.Close();
request.ContentLength = fileContents.Length;
request.UsePassive = true;
Stream requestStream = request.GetRequestStream();
requestStream.Write(fileContents, 0, fileContents.Length);
requestStream.Close();
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
Console.WriteLine("Upload File Complete, status {0}", response.StatusDescription);
response.Close();
and I get an Error in request.GetRequestStream(); the error is: the remote server returned error 530 not logged in if I try to go in to a browser page and in the url I write ftp://192.168.20.10/the brows page is asking me for a name and password, I put the same name and password and I see all the files and folders in the ftp folder.
我在 request.GetRequestStream() 中遇到错误；错误是：如果我尝试进入浏览器页面，则远程服务器返回错误 530 未登录，并且在 url 中我写ftp://192.168.20.10/浏览页面 要求我输入名称和密码，我输入相同的名称和密码，我会看到 ftp 文件夹中的所有文件和文件夹。

Shouldn't the line:
不应该是：
request.Credentials = new NetworkCredential("dev\ftp", "devftp");
be:
是：
request.Credentials = new NetworkCredential("dev\ftp", "devftp");
or:
或者：
request.Credentials = new NetworkCredential(@"dev\ftp", "devftp");
I have to believe this may be causing your issues because the \f is a form feed character.
我不得不相信这可能会导致您的问题，因为 \f 是换页符。

I found out that when connecting via .NET/C# to a FTP-server some characters are not "valid". After setting the login credentials to only only letters and numbers [a-Z0-9] it worked to log in.
我发现当通过 .NET/C# 连接到 FTP 服务器时，某些字符不是“有效”的。将登录凭据设置为仅字母和数字 [a-Z0-9] 后，它就可以登录了。

Just remove the double quote from username or password because sometimes $ sign in username or password causes problem. Its good to use single quote every time.
只需从用户名或密码中删除双引号，因为有时 $ 登录用户名或密码会导致问题。每次都使用单引号很好。

If you assume anonymous logon do not set network credentials. this was the root of my problems.
如果您假设匿名登录，请不要设置网络凭据。这是我问题的根源。
