我目前正在尝试编写TCP客户端/服务器应用程序。我觉得自己做得很差，因为我对C＃（来自Java）很陌生。
我的客户有这段代码：
public static void SendPlejeFamilieObjekt(PlejeFamilie pfamilie)
{
try
{
InitConnection();
if (_isConnected)
{
_sWriter.WriteLine("SEND_PLEJEFAMILIE");
if (_sReader.ReadLine().Equals("AUTH_GIVEN"))
{
#region Send Plejefamilie Objekt
_sWriter.WriteLine(pfamilie.CPRKvinde);
_sWriter.WriteLine(pfamilie.CPRMand);
_sWriter.WriteLine(pfamilie.NavnKvinde);
_sWriter.WriteLine(pfamilie.NavnMand);
_sWriter.WriteLine(pfamilie.Addresse);
_sWriter.WriteLine(pfamilie.MobilKvinde);
_sWriter.WriteLine(pfamilie.MobilMand);
_sWriter.WriteLine(pfamilie.HjemmeTelefon);
_sWriter.WriteLine(pfamilie.StillingKvinde);
_sWriter.WriteLine(pfamilie.StillingMand);
_sWriter.WriteLine(pfamilie.EmailKvinde);
_sWriter.WriteLine(pfamilie.EmailMand);
_sWriter.WriteLine(pfamilie.EmailFaelles);
_sWriter.WriteLine(pfamilie.GodkendtDato.ToShortDateString());
_sWriter.WriteLine(pfamilie.PlejeForaeldreUdd);
_sWriter.WriteLine(pfamilie.AntalKurserIAar);
_sWriter.WriteLine(pfamilie.AntalBoernGodkendt);
_sWriter.WriteLine(pfamilie.Vilkaar);
_sWriter.WriteLine(pfamilie.Status);
#endregion Send Plejefamilie Objekt
}
}
}
finally
{
EndConnection();
}
}
它一直用于发送“SEND_PLEJEFAMILIE”。我通过打印到控制台检查了这一点。
现在在我的服务器代码中，它看起来像这样：
private static void HandleClient(object obj)
{
TcpClient client = (TcpClient)obj;
Console.WriteLine("Handling client: {0}", client.Client.LocalEndPoint.ToString());
StreamWriter sWriter = new StreamWriter(client.GetStream(), Encoding.ASCII);
StreamReader sReader = new StreamReader(client.GetStream(), Encoding.ASCII);
Console.WriteLine("Streams Acquired");
bool bClientConnected = client.Connected;
Console.WriteLine("bClientConnected {0}", bClientConnected.ToString());
String sData = sReader.ReadLine();
List<String> list;
List<Note> nList;
List<Note> nList2;
while (bClientConnected)
{
Console.WriteLine(sData);
switch (sData)
{
#region Modtag Plejefamilie
case "SEND_PLEJEFAMILIE":
Console.WriteLine("Receiving PlejeFamilie");
sWriter.WriteLine("AUTH_GIVEN");
sWriter.Flush();
Console.WriteLine("AUTH_GIVEN");
list = new List<String>();
while (!(sData = sReader.ReadLine()).Equals("END"))
{
list.Add(sData);
}
ServerPlejeFamilie spf = new ServerPlejeFamilie();
spf.Info = list;
pfStack.Push(spf);
Console.WriteLine("Received {0}", spf.Info[0]);
break;
程序在此行代码后停止运行：Console.WriteLine("bClientConnected {0}", bClientConnected.ToString());
我无法弄清楚原因。 以下是这两个类的所有代码，以备不时之需：

答案 0 :(得分：0)
尝试添加_sWriter.Flush（）;在_sWriter.WriteLine之后（“SEND_PLEJEFAMILIE”）;在客户端代码中。
