我在這裏發現了一些類似的文章，但仍無法解決我的問題。 我正嘗試將文本文件上傳到FTP服務器。我用了一些方法和所有的人我得到同樣的錯誤：「無法連接到遠程服務器」到服務器的FTP請求無法連接遠程服務器
方法一： 文件名是該文件所在的完整路徑
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：\文件夾\ file.txt的」 公共靜態無效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();
}
使用他們每個人產生同樣的問題，是的，我能夠通過使用FileZilla的連接到FTP，並傳輸文件。
我知道我必須失去一些非常愚蠢的東西，但是這讓我感到非常沮喪。 任何建議都會被處理。
