调用远端接口，向远端接口写入一个xml文件（loginLog为xml的字符串）。关键方法如下：
public object InsertAuditLog(string loginLog) { //Wsdlxml(loginLog)返回wsdl的xml byte[] bs = Encoding.UTF8.GetBytes(Wsdlxml(loginLog)); HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://10.109.209.90:21010/gather/services/AioxPort"); myRequest.Method = "POST"; myRequest.ContentType = "text/xml; charset=utf-8"; //mediate为调用方法 myRequest.Headers.Add("SOAPAction", "http://tempuri.org/mediate"); myRequest.ContentLength = bs.Length; //Console.WriteLine("完成准备工作"); using (Stream reqStream = myRequest.GetRequestStream()) { reqStream.Write(bs, 0, bs.Length); } using (HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse()) { StreamReader sr = new StreamReader(myResponse.GetResponseStream(), Encoding.UTF8); return sr.ReadToEnd(); //Console.WriteLine("反馈结果" + responseString); } //Console.WriteLine("完成调用接口"); }
自己项目中的完整应用代码如下（备忘）：

try { InsertAuditLog(loginLog); string updateSql = string.Format(@"update CC_LOGIN_HISTORY set tag=1 where ID={0}", Convert.ToInt32(dr["ID"].ToString())); ExecuteNonQuery(updateSql);//修改已写入4a登录日志 } catch { } //if (i > 1) //{ // loginLogList = null;

} using (HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse()) { StreamReader sr = new StreamReader(myResponse.GetResponseStream(), Encoding.UTF8); var rs = sr.ReadToEnd(); return rs;
