Mar 17 2015 7:06 AM
i am writing a program to transfer file using socket programing in c# i am getting this error
 
"No connection could be made because the target machine actively refused it ::1:5656"
 
my code where error is occuring is
IPAddress[] ipAddress = Dns.GetHostAddresses("localhost");
IPEndPoint ipEnd = new IPEndPoint(ipAddress[0], 5656);
Socket clientSock = new Socket(AddressFamily.InterNetworkV6, SocketType.Stream, ProtocolType.IP);
string filePath = "";
fileName = fileName.Replace("\\", "/");
while (fileName.IndexOf("/") > -1)
{
filePath += fileName.Substring(0, fileName.IndexOf("/") + 1);
fileName = fileName.Substring(fileName.IndexOf("/") + 1);
}
byte[] fileNameByte = Encoding.ASCII.GetBytes(fileName);
if (fileNameByte.Length > 850 * 1024)
{
curMsg = "File size is more than 850kb, please try with small file.";
return;
}
curMsg = "Buffering ...";
byte[] fileData = File.ReadAllBytes(filePath + fileName);
byte[] clientData = new byte[4 + fileNameByte.Length + fileData.Length];
byte[] fileNameLen = BitConverter.GetBytes(fileNameByte.Length);
fileNameLen.CopyTo(clientData, 0);
fileNameByte.CopyTo(clientData, 4);
fileData.CopyTo(clientData, 4 + fileNameByte.Length);
curMsg = "Connection to server ...";
clientSock.Connect(ipEnd); // here i am getting the error 
curMsg = "File sending...";
clientSock.Send(clientData);
curMsg = "Disconnecting...";
clientSock.Close();
curMsg = "File transferred.";
