socket服务端异步通信

willyouasd 2010-07-09 11:21:42

源代码如下：
客户端接入的时候，
单步调试能进入while（true），步进到reset，但是却不调用listenOK那个回调方法
求助

namespace d_webListener
{
public class d_webListener
{
private Thread serverRun;
private String ip = "";

sw.Write(s);
sw.Flush();
sw.Close();

s = s.Insert(s.IndexOf("HTTP/1.1") - 1, "\r\n");
xm.createFileInMem();
xm.addNodeInMem("FUND_ACCOUNT", "102045459");

cc1.creatStruct(xm.doc().Length, xm.doc().Length, 400, 'M', 0);
