            public static void SendFile(string fileName)
            {
                try

                    IPAddress[] ipAddress = Dns.GetHostAddresses(str);
                    IPEndPoint ipEnd = new IPEndPoint(ipAddress[0], 5656);
                    Socket clientSock = new Socket(AddressFamily.InterNetwork, 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);

                    curMsg = "File sending...";
                    clientSock.Send(clientData);

                    curMsg = "Disconnecting...";
                    clientSock.Close();
                    curMsg = "File transferred.";

                }

                {
                    if (ex.Message == "No connection could be made because the target machine actively refused it")
                        curMsg = "File Sending fail. Because server not running.";

are you looking to override ToString() method?

_Maxxx_ 28-Feb-12 0:48am

I'm not clear on 'where' you want to get the value from your combo into your class? Essentially, you probably need a property in the class that you set to the selected value, when the combo changes value.

get the string value in str
try
{

IPAddress[] ipAddress = Dns.GetHostAddresses(str);

Not clear. How about using "improve question" above?

IPAddress[] ipAddress = Dns.GetHostAddresses(str);

in this above line i want to get the combobox selected item in string[str]

Could you explain: why this question is nearly identical to this one:

???

In your class add a property

public static string HostAddressString {get;set;}

Write an event handler for the IndexChanged event on the combo - and in that handler

FTClientCode.HostAddressString = combobox.SelectedItem.ToString();

so, in the class you can access HostAddressString

IPAddress[] ipAddress = Dns.GetHostAddresses(HostAddressString);

Solution 1

Have a look at this link... from CodeProject

An INI file handling class using C#[^]

This may give you an idea
