How to connect to local socket in c #?

Question

I am trying to adapt this python code that I found to connect to the Dropbox daemon:

def connect(self, cmd_socket="~/.dropbox/command_socket", iface_socket="~/.dropbox/iface_socket"): "Connects to the Dropbox command_socket, returns True if it was successfull." self.iface_sck = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM) self.sck = socket.socket(socket.AF_UNIX, socket.SOCK_STREAM) try: self.sck.connect(os.path.expanduser(cmd_socket)) # try to connect self.iface_sck.connect(os.path.expanduser(iface_socket)) except: self.connected = False return False else: # went smooth self.connected = True return True 

Here is what I still have:

 public bool Connect (int port) { return Connect ("~/.dropbox/command_socket", "~/.dropbox/iface_socket", port); } public bool Connect (string cmdSocket, string ifaceSocket, int port) { IfaceSocket = new Socket (AddressFamily.Unix, SocketType.Stream, ProtocolType.IP); CmdSocket = new Socket (AddressFamily.Unix, SocketType.Stream, ProtocolType.IP); try { // ExpandUser replaces a leading "/~" with the user home directory IPAddress [] CmdIPs = Dns.GetHostAddresses (ExpandUser (cmdSocket)); CmdSocket.Connect (CmdIPs [0], port); IPAddress [] IfaceIPs = Dns.GetHostAddresses (ExpandUser (ifaceSocket)); IfaceSocket.Connect (IfaceIPs [0], port); } catch (Exception e) { // Debug Console.WriteLine (e); Connected = false; return false; } Connected = true; return true; } 

This compiles fine, but when I try to run it, I get a System.Net.Sockets.SocketException: No such host is known . I assume this is because cmdSocket and ifaceSocket are paths, not IP addresses. Python seems to handle this automatically, how do I do this in C #? This is my first foray into socket programming, so please indicate any obvious errors.

You need to use Mono.Unix.UnixEndPoint from Mono.Posix.dll instead of IPEndPoint. Everything else is the same. See an example of how XSP uses it here .
