微信退款时报错(ThreadAbortException)

在微信退款时会报错,但是只是偶尔会报错,报错日志如下:

2019-05-17 15:03:15.755 ERROR HttpService: Thread - caught ThreadAbortException - resetting.
2019-05-17 15:03:15.772 ERROR Exception message: {0}: 正在中止线程。
2019-05-17 15:03:15.789 DEBUG WxPayApi: Refund response :
2019-05-17 15:03:15.806 ERROR WxPayAPI.WxPayData: 将空的xml串转换为WxPayData不合法!

查看源码,发现是WxPayAPI.HttpService.Post方法报错,方法源码如下:

public static string Post(string xml, string url, bool isUseCert, int timeout)
        {
            System.GC.Collect();//垃圾回收,回收没有正常关闭的http连接
 
            string result = "";//返回结果
 
            HttpWebRequest request = null;
            HttpWebResponse response = null;
            Stream reqStream = null;
 
            try
            {
                //设置最大连接数
                ServicePointManager.DefaultConnectionLimit = 200;
                //设置https验证方式
                if (url.StartsWith("https", StringComparison.OrdinalIgnoreCase))
                {
                    ServicePointManager.ServerCertificateValidationCallback =
                            new RemoteCertificateValidationCallback(CheckValidationResult);
                }
 
                /***************************************************************
                * 下面设置HttpWebRequest的相关属性
                * ************************************************************/
                request = (HttpWebRequest)WebRequest.Create(url);
                request.UserAgent = USER_AGENT;
 
                request.Method = "POST";
                request.Timeout = timeout * 1000;
 
                //设置代理服务器
                //WebProxy proxy = new WebProxy();                          //定义一个网关对象
                //proxy.Address = new Uri(WxPayConfig.PROXY_URL);              //网关服务器端口:端口
                //request.Proxy = proxy;
 
                //设置POST的数据类型和长度
                request.ContentType = "text/xml";
                byte[] data = System.Text.Encoding.UTF8.GetBytes(xml);
                request.ContentLength = data.Length;
 
                //是否使用证书
                if (isUseCert)
                {
                    string path = HttpContext.Current.Request.PhysicalApplicationPath;
                    X509Certificate2 cert = new X509Certificate2(path + WxPayConfig.SSLCERT_PATH, WxPayConfig.SSLCERT_PASSWORD);
                    request.ClientCertificates.Add(cert);
                    Log.Debug("WxPayApi", "PostXml used cert");
                }
 
                //往服务器写入数据
                reqStream = request.GetRequestStream();
                reqStream.Write(data, 0, data.Length);
                reqStream.Close();
 
                //获取服务端返回
                response = (HttpWebResponse)request.GetResponse();
 
                //获取服务端返回数据
                StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
                result = sr.ReadToEnd().Trim();
                sr.Close();
            }
            catch (System.Threading.ThreadAbortException e)
            {
                Log.Error("HttpService", "Thread - caught ThreadAbortException - resetting.");
                Log.Error("Exception message: {0}", e.Message);
                System.Threading.Thread.ResetAbort();
            }
            catch (WebException e)
            {
                Log.Error("HttpService", e.ToString());
                if (e.Status == WebExceptionStatus.ProtocolError)
                {
                    Log.Error("HttpService", "StatusCode : " + ((HttpWebResponse)e.Response).StatusCode);
                    Log.Error("HttpService", "StatusDescription : " + ((HttpWebResponse)e.Response).StatusDescription);
                }
                throw new WxPayException(e.ToString());
            }
            catch (Exception e)
            {
                Log.Error("HttpService", e.ToString());
                throw new WxPayException(e.ToString());
            }
            finally
            {
                //关闭连接和流
                if (response != null)
                {
                    response.Close();
                }
                if(request != null)
                {
                    request.Abort();
                }
            }
            return result;
        }

在网上看了一下,应该是并发访问出的问题,各位大佬是否有好的优化方法来解决呢?
