C# 如何发送2个xml请求soap？

我有一个包含两个XML字符串的列表，下面是C代码：

字符串sb=”“；
List LISTGAME=新列表（）；
sb=（“在代码中应用循环以逐个发送请求。如果wsdl不允许，则不能同时发送两个请求

在wsdl中检查您的请求消息格式，它是否将请求作为您在代码中定义的字符串列表

对于列表中的每个字符串，重复以下代码

HttpWebRequest req = (HttpWebRequest)WebRequest.Create("urlofmy.asmx");

请求标题添加（“SOAPAction”、“URLSOAAPAction”）；
req.ContentType=“text/xml；字符集=\”utf-8\”；
req.Accept=“text/xml”；
请求方法=“POST”

对于每个xml请求，您还将得到多个响应

还有一件事，您可以从wsdl粘贴您的请求消息结构。可能是您可以在单个请求消息中发送多个rquest（取决于您的wsdl请求消息结构）

编辑代码：

string sb = "";
List<string> listGamme = new List<string>();
sb = ("<?xml....") ;//1st listGamme
listGamme.Add(sb);
sb = ("<?xml..."); //2nd listGamme
listGamme.Add(sb);

foreach (string gamme in listGamme)
                        {
    HttpWebRequest req = (HttpWebRequest)WebRequest.Create("urlofmy.asmx");
    req.Headers.Add("SOAPAction", "URLSOAPACTION");
    req.ContentType = "text/xml;charset=\"utf-8\"";
    req.Accept = "text/xml";
    req.Method = "POST";


            using (Stream stm = req.GetRequestStream())
            {

                using (StreamWriter stmw = new StreamWriter(stm))
                {

                             stmw.Write(gamme); 

                 }

            }

    WebResponse response = req.GetResponse();
    StreamReader srreader = new StreamReader(response.GetResponseStream());
}

字符串sb=”“；
List LISTGAME=新列表（）；
sb=（“如何应用循环来逐个发送请求？我得到了这个消息系统。ArgumentException:流不可写请将您的wsdl粘贴到这里。我只需要它的请求消息结构。有什么原因不能简单地使用“添加服务引用”？请参阅
