在C语言中制作一个聊天程序，你将如何创建一个ftp功能

我已经为我的FTP创建了一个聊天程序和一个GUI。我已经编写了我认为适用于FTP的代码，但是当我运行解决方案时，它总是给我不同的结果。也就是说，它每次使用不同的内存集创建文件。这是相关的编码，当它被传输回客户端时，问题似乎发生了：

在服务器中：

    //Listens for new commands coming in from the client associated with the client object
    public void Command_Listener()
    {
        foreach (Client C in UI[0].clients)
        {
            sw.WriteLine("2: User: " + username + " has connected...");
            sw.Flush();
            //Notifies other client objects inside the user interface that this one is operational
        }
        while (UI[0].busy)
        { } //waits for the log to not be busy with another task then declares this task is over
        UI[0].busy = true;
        UI[0].Log_Event(username + " has connected..." + DateTime.Now.ToString());
        UI[0].Log_Event("Client username : " + Client_Info[0]);
        UI[0].Log_Event("Client computer name : " + Client_Info[1]);
        UI[0].Log_Event("Client operating system : " + Client_Info[2]);
        UI[0].Log_Event("Client lan IP address : " + Client_Info[3]);
        UI[0].Log_Event("Client wan IP address : " + Client_Info[4]);
        //sends the client info from the client to the server's user interface and the log
        UI[0].busy = false;
        while (true)
        {
            try
            {
                string command = sr.ReadLine();
                //waits for a new message
                if (command[0] == '1')
                    Update_Chat_List(command.Replace("1: ", ""));
                    //Determines the Username has changed and needs to update the list
                if (command[0] == '2')
                    Update_Message_Board(command.Replace("2: ", ""));
                    //Determines the message board on each clients needs to update with the new command included
                if (command == "3: typing" && !typing) //Determines the client's typing
                {
                    typing = true;
                    Update_Chat_List(username);
                }
                if (command == "3: empty" && typing) //Determine the client's not typing
                {
                    typing = false;
                    Update_Chat_List(username);
                }
                if (command[0] == '5') //Determines that a new FTP is in progress
                    Update_FTP_Status(command.Replace("5: ", ""));
                if (command[0] == '6')
                {
                    //Adds the incoming kilobyte of the file to a string list
                    kilos.Add(command.Replace("<heartbeat>", ""));
                }
                if (command[0] == '7')
                {
                    //Tells the server that all pieces of the file have been recieved
                    kilos.Add(command);
                    new Thread(Send_File).Start();
                }
            }
            catch //catchs all listening problems and tells the server the client must be removed and then does a user list update and logs the exit
            {

                sr.Dispose();
                UI[0].clients.RemoveAt(Client_Index);

                foreach (Client C in UI[0].clients)

                return;
            }
        }
    }

    public void Send_File() 
    {
        string last = "";
        foreach (string kilo in kilos)
        {
            FTP_Connection[0].sw.WriteLine(kilo);
            FTP_Connection[0].sw.Flush();
            //sends all part of the file and the closing compile command for the client
        }
        ftping = false;
        int length = last.Length;
        FTP_Connection[0].ftping = false;

            }
        }
    }

在客户端：
