是用winfrom做的测试，大家如果想用asp教程。net也是一样的，把我的方法复制到你的web页面的cs代码下就ok了。

好了我们的分析到这里就算是结束了，

在这里我再给大空补充一个关于调用带有证书的网站的调用 方法

因为带证书的都是在要验证证书文件的，我们在这里直接让他在本地回调验证，这样的话就要吧重写方法了，下在看一下回调的方法吧

//回调验证证书问题

        public bool checkvalidationresult(object sender, x509certificate certificate, x509chain chain, sslpolicyerrors errors)
        {   // 总是接受   
            return true;
        }

其它很简单只要在 我们上面的方法geturltohtml（）中加入几行代码就行了，修改后的方法

///

        /// 传入url返回网页的html代码
        ///

        /// url
        ///
        public string geturltohtml(string url)
        {
            stringbuilder content = new stringbuilder();
            try
            {
                // 与指定url创建http请求
                servicepointmanager.servercertificatevalidationcallback = new system.net.security.remotecertificatevalidationcallback(checkvalidationresult);//验证

                httpwebrequest request = (httpwebrequest)webrequest.create(url);
                request.keepalive = false;
                request.useragent = "mozilla/4.0 (compatible; msie 7.0; windows nt 6.1; trident/5.0; slcc2; .net clr 2.0.50727; .net clr 3.5.30729; .net clr 3.0.30729; media center pc 6.0; infopath.2; ms-rtc lm 8; .net4.0c; .net4.0e)";
                request.method = "get";
                request.accept = "*/*";

                //创建证书文件
                x509certificate objx509 = new x509certificate(application.startuppath + "123.cer");

                //添加到请求里
                request.clientcertificates.add(objx509);

                httpwebresponse response = (httpwebresponse)request.getresponse();
                // 获取对应http请求的响应
                // 获取响应流
                stream responsestream = response.getresponsestream();
                // 对接响应流(以"gbk"字符集)
                streamreader sreader = new streamreader(responsestream, encoding.getencoding("gbk"));
                // 开始读取数据
                char[] sreaderbuffer = new char[256];
                int count = sreader.read(sreaderbuffer, 0, 256);
                while (count > 0)
                {
                    string tempstr = new string(sreaderbuffer, 0, count);
                    content.append(tempstr);
                    count = sreader.read(sreaderbuffer, 0, 256);
                }
                // 读取结束
                sreader.close();
            }
            catch (exception)
            {
                content = new stringbuilder("runtime error");
            }

            return content.tostring();

        }
