下面是服務器端代碼：

// Learn more about F# at http://fsharp.net // See the 'F# Tutorial' project for more help. open System.Net.Sockets open System.Net open System.IO open System open System.Collections.Generictype System.Net.Sockets.TcpListener withmember this.AsyncAcceptTcpClient() =Async.FromBeginEnd(this.BeginAcceptTcpClient,this.EndAcceptTcpClient)type Server() =classmember this.Start() = let tcpListener = new TcpListener(System.Net.IPAddress.Loopback, 4242)tcpListener.Start()while(true) doif(tcpListener.Pending()) then let proc =async{trylet! client = tcpListener.AsyncAcceptTcpClient()let strPipe = client.GetStream()let strReader = new StreamReader(strPipe)let strWriter = new StreamWriter(strPipe)while(true) do let buffer = Array.create 216 0uylet read = strPipe.Read(buffer,0,216)let allText = System.Text.Encoding.UTF8.GetString(buffer,0,read)printfn "Recieve from client: %s" (allText)strWriter.Write("Got From Server:")allText |> strWriter.WriteLinestrWriter.Flush()with _ -> printfn "丟失連接，重新連接吧"}proc |> Async.Startend [<EntryPoint>] let main argv = (new Server()).Start()0 // return an integer exit code

客戶端代碼：

?更新一下， 支持異步運行。 多個Form同時運行。 下個版本實現多個之間交流。。
