为了方便跟踪服务器端代码，可以通过写日志的形式查找问题。

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
 
namespace kongqx
{
    class LogClass
    {
         /**//// <summary>
         /// 写入日志文件
         /// </summary>
         /// <param name="input"></param>
         public void WriteLogFile(string input)
        {
            /**/
            ///指定日志文件的目录
            string fname = Directory.GetCurrentDirectory() + "\\LogFile.txt";
            /**/
            ///定义文件信息对象
 
            FileInfo finfo = new FileInfo(fname);
 
            if (!finfo.Exists)
            {
                FileStream fs;
                fs = File.Create(fname);
                fs.Close();
                finfo = new FileInfo(fname);
            }
 
            /**/
            ///判断文件是否存在以及是否大于2K
            if (finfo.Length > 1024 * 1024 * 10)
            {
                /**/
                ///文件超过10MB则重命名
                File.Move(Directory.GetCurrentDirectory() + "\\LogFile.txt", Directory.GetCurrentDirectory() + DateTime.Now.TimeOfDay + "\\LogFile.txt");
                /**/
                ///删除该文件
                //finfo.Delete();
            }
            //finfo.AppendText();
            /**/
            ///创建只写文件流
 
            using (FileStream fs = finfo.OpenWrite())
            {
                /**/
                ///根据上面创建的文件流创建写数据流
                StreamWriter w = new StreamWriter(fs);
 
                /**/
                ///设置写数据流的起始位置为文件流的末尾
                w.BaseStream.Seek(0, SeekOrigin.End);
 
                /**/
                ///写入“Log Entry : ”
                w.Write("\n\rLog Entry : ");
 
                /**/
                ///写入当前系统时间并换行
                w.Write("{0} {1} \n\r", DateTime.Now.ToLongTimeString(),
                    DateTime.Now.ToLongDateString());
 
                /**/
                ///写入日志内容并换行
                w.Write(input + "\n\r");
 
                /**/
                ///写入------------------------------------“并换行
                w.Write("------------------------------------\n\r");
 
                /**/
                ///清空缓冲区内容，并把缓冲区内容写入基础流
                w.Flush();
 
                /**/
                ///关闭写数据流
                w.Close();
            }
             
        }
    }
}
