我在这里发现了一些类似的文章，但仍无法解决我的问题。 我正尝试将文本文件上传到FTP服务器。我用了一些方法和所有的人我得到同样的错误：“无法连接到远程服务器”到服务器的FTP请求无法连接远程服务器
方法一： 文件名是该文件所在的完整路径
private string Upload(string ftpServer, string userName, string password, string filename)
{
string reply = "Success";
try
{
using (System.Net.WebClient client = new System.Net.WebClient()) //System.Net.WebClient client = new System.Net.WebClient()
{
client.Credentials = new System.Net.NetworkCredential(userName, password);
client.Proxy = new WebProxy();
FileInfo fi = new FileInfo(filename);
client.UploadFile(ftpServer + "//" + fi.Name, "STOR", filename);
}
}
catch (Exception ex)
{
reply = ex.Message;
}
return reply;
}
方法2：
文件名= “d：\文件夹\ file.txt的” 公共静态无效uploadFileUsingFTP（字符串文件名） { 的FileInfo fileInf =新的FileInfo（文件名）; string uri =“ftp：//”+ serverIP +“/”+ fileInf.Name;
FtpWebRequest reqFTP;
// Create FtpWebRequest object from the Uri provided
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(uri));
reqFTP.Proxy = null;
// Provide the WebPermission Credintials
reqFTP.Credentials = new NetworkCredential(user, pass);
// By default KeepAlive is true, where the control connection is not closed
// after a command is executed.
reqFTP.KeepAlive = false;
// Specify the command to be executed.
reqFTP.Method = WebRequestMethods.Ftp.UploadFile;
// Specify the data transfer type.
reqFTP.UseBinary = true;
// Notify the server about the size of the uploaded file
FileStream fs = File.OpenRead(filename);
reqFTP.ContentLength = fileInf.Length;
// The buffer size is set to 2kb
int buffLength = Convert.ToInt32(fs.Length);
byte[] buff = new byte[buffLength];
int contentLen;
try
{
// Stream to which the file to be upload is written
Stream strm = reqFTP.GetRequestStream();
// Read from the file stream 2kb at a time
contentLen = fs.Read(buff, 0, buffLength);
// Till Stream content ends
while (contentLen != 0)
{
// Write Content from the file stream to the FTP Upload Stream
strm.Write(buff, 0, contentLen);
contentLen = fs.Read(buff, 0, buffLength);
}
// Close the file stream and the Request Stream
strm.Close();
fs.Close();
}
catch (Exception ex)
{
string s = ex.Message;
}
}
方法3：
public static void Sample(string filename)
{
// Get the object used to communicate with the server.
FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://serverip/"); //test.htm
request.Method = WebRequestMethods.Ftp.UploadFile;
// This example assumes the FTP site uses anonymous logon.
request.Credentials = new NetworkCredential (user,passs);
try
{
// Copy the contents of the file to the request stream.
StreamReader sourceStream = new StreamReader(filename);
byte[] fileContents = Encoding.UTF8.GetBytes(sourceStream.ReadToEnd());
sourceStream.Close();
request.ContentLength = fileContents.Length;
request.Proxy = null;
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();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
Console.ReadLine();
}
使用他们每个人产生同样的问题，是的，我能够通过使用FileZilla的连接到FTP，并传输文件。
我知道我必须失去一些非常愚蠢的东西，但是这让我感到非常沮丧。 任何建议都会被处理。
