问题:  
----------------------------------------------------
当执行上面函数后, 再执行另外一个相似函数, 会抛异常当执行上面函数后, sleep下，再执行另外一个相似函数, 不会抛异常直接执行另外一个相似函数, 不会抛异常
------------------------------------------------------我感觉就是上面代码有问题,  谁帮我看看

Answer 1

当执行上面函数后, 再执行另外一个相似函数, 会抛异常当执行上面函数后, sleep下，再执行另外一个相似函数, 不会抛异常直接执行另外一个相似函数, 不会抛异常看样子应该是资源访问冲突了，你说的另外一个相似函数贴出来看看吧

Answer 2

CLog.WriteLog("CaptchaDeal start");这句

Answer 3

       //返回 0 成功注册 1 帐户错误 2 网络不通 3 验证码错误 4登陆次数过多 
        public int RegPost(ref TAccountInfo tAccountInfo)
        {            CLog.WriteLog("RegPost start");            string url = "http://***";            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
            request.Method = "POST";
            request.ContentType = "application/x-www-form-urlencoded";
            request.Headers.Add("Accept-Language", "zh-CN");            request.ServicePoint.Expect100Continue = false;
            request.CookieContainer = m_cookieContainer;            //填充要post的内容
            string strPostData = "***";            byte[] bytesToPost = Encoding.ASCII.GetBytes(strPostData);
            request.ContentLength = bytesToPost.Length;
            //request.AllowAutoRedirect = false;            Stream requestStream = null;            try
            {
                requestStream = request.GetRequestStream();
                requestStream.Write(bytesToPost, 0, bytesToPost.Length);
            }
            catch
            {
                if (requestStream != null)
                {
                    requestStream.Dispose();
                }
                request.Abort();                CLog.WriteLog("RegPost end 1");                return 2;
            }            requestStream.Close();            int nStatus = 0;            try
            {
                HttpWebResponse response = (HttpWebResponse)request.GetResponse();                nStatus = response.StatusCode.GetHashCode();                Stream responseStream = response.GetResponseStream();                StreamReader readStream = new StreamReader(responseStream, System.Text.Encoding.UTF8);
                string page = readStream.ReadToEnd();
                response.Close();                CLog.WriteLog("RegPost end 2");                //如果登陆失败,分析原因
                //分析结果
                if (IsYZMWrong(ref  page))
                {
                    return 3;// 验证码错误      
                }
                else if (IsLoginSuccess(ref  page))//成功
                {
                    return 0;
                }
                else
                {
                    return 1;// 帐户密码错误
                }
            }
            catch
            {
                CLog.WriteLog("RegPost end 3");
              
                request.Abort();
                return 2;
            }
        }
贴了, 另外调试情况下也没有问题

Answer 4

response和responseStream的声明放在try外边，在catch中判断是否为null，不为null就关闭

Answer 5

当执行上面函数后, 再执行另外一个相似函数, 会抛异常 //CLog.WriteLog("RegPost end 3"); 当执行上面函数后, sleep下，再执行另外一个相似函数, 不会抛异常//CLog.WriteLog("RegPost end 2");
直接执行另外一个相似函数, 不会抛异常//CLog.WriteLog("RegPost end 2");

Answer 6

我刚才测试一下，没有抱错。我不知道你的函数有多相似，我改变了URL

Answer 7

catch(Exception ex)
{
CLog.WriteLog(ex.ToString());
}
看看到底是什么错呢………………
