使用 C# 读取 Soap 消息

Read Soap Message using C#

提问by delwasaf ewrew

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Head>
    <h:talkId s:mustknow="1" xmlns:h="urn:schemas-test:testgate:hotel:2012-06">
      sfasfasfasfsfsf</h:talkId>
    </s:Head>
  <s:Body>
    <bookHotelResponse xmlns="urn:schemas-test:testgate:hotel:2012-06" xmlns:d="http://someURL" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
      <d:bookingReference>123456</d:bookingReference>
      <d:bookingStatus>successful</d:bookingStatus>
      <d:price xmlns:p="moreURL">
        <d:total>105</d:total>
      </d:price>
    </bookHotelResponse>
  </s:Body>
</s:Envelope>

I am trying to read the above soap message XmlDocumentusing C#:

我正在尝试XmlDocument使用 C#阅读上述肥皂消息：

XmlDocument document = new XmlDocument();
document.LoadXml(soapmessage);  //loading soap message as string
XmlNamespaceManager manager = new XmlNamespaceManager(document.NameTable);

manager.AddNamespace("d", "http://someURL");

XmlNodeList xnList = document.SelectNodes("//bookHotelResponse", manager);
int nodes = xnList.Count;

foreach (XmlNode xn in xnList)
{
    Status = xn["d:bookingStatus"].InnerText;
}

The count is always zero and it is not reading the bookingstatus values.

计数始终为零，并且不读取预订状态值。

BookHotelResponseis in the namespace urn:schemas-test:testgate:hotel:2012-06(the default namespace in the sample xml) so you need to provide that namespace in your queries:

BookHotelResponse位于命名空间urn:schemas-test:testgate:hotel:2012-06（示例 xml 中的默认命名空间）中，因此您需要在查询中提供该命名空间：

XmlDocument document = new XmlDocument(); 
document.LoadXml(soapmessage);  //loading soap message as string 
XmlNamespaceManager manager = new XmlNamespaceManager(document.NameTable); 

manager.AddNamespace("d", "http://someURL"); 
manager.AddNamespace("bhr", "urn:schemas-test:testgate:hotel:2012-06"); 

XmlNodeList xnList = document.SelectNodes("//bhr:bookHotelResponse", manager); 
int nodes = xnList.Count; 

foreach (XmlNode xn in xnList) 
{ 
    Status = xn["d:bookingStatus"].InnerText; 
}

Use LINQ2XML

用 LINQ2XML

To read bookingStatus,do this

要阅读预订状态，请执行此操作

XElement doc = XElement.Load("yourStream.xml");
XNamespace s = "http://schemas.xmlsoap.org/soap/envelope/";//Envelop namespace s
XNamespace bhr="urn:schemas-test:testgate:hotel:2012-06";//bookHotelResponse namespace
XNamespace d="http://someURL";//d namespace

foreach (var itm in doc.Descendants(s + "Body").Descendants(bhr+"bookHotelResponse"))
{
itm.Element(d+"bookingStatus").Value;//your bookingStatus value
}

LINQ2XML is coolthough....:)

不过 LINQ2XML很酷....:)

First you want to create a class to deseralize the xml values into

首先，您要创建一个类来将 xml 值反序列化为

    public class bookHotelResponse {
      public int bookingReference { get; set; }
      public int bookingStatus { get; set; }
   } 

Then you can utilize GetElementsByTagNameto extract the body of the soap request and deseralize the request string into an object.

然后你可以利用GetElementsByTagName来提取soap请求的主体并将请求字符串反序列化为一个对象。

    private static T DeserializeInnerSoapObject<T>(string soapResponse)
    {
        XmlDocument xmlDocument = new XmlDocument();
        xmlDocument.LoadXml(soapResponse);

        var soapBody = xmlDocument.GetElementsByTagName("soap:Body")[0];
        string innerObject = soapBody.InnerXml;

        XmlSerializer deserializer = new XmlSerializer(typeof(T));

        using (StringReader reader = new StringReader(innerObject))
        {
            return (T)deserializer.Deserialize(reader);
        }
    }

As I understand you want to get response from soap service. If so, you don't have to do all this hard work (making call, parsing xml, selecting nodes to get the response value) by yourself... instead you need to Add Service Reference to your project and it will do all the rest work for you, including generating class, making asmx call and so on... Read more about it here https://msdn.microsoft.com/en-us/library/bb628649.aspx

据我了解，您希望得到肥皂服务的响应。如果是这样，您不必自己完成所有这些艰苦的工作（拨打电话、解析 xml、选择节点以获取响应值）...相反，您需要将服务引用添加到您的项目中，它会完成所有的工作为您休息工作，包括生成类，进行 asmx 调用等...在此处阅读更多相关信息https://msdn.microsoft.com/en-us/library/bb628649.aspx

Everything you'll need to do after adding reference is to invoke a class method something like this

添加引用后您需要做的一切就是调用这样的类方法

var latestRates = (new GateSoapClient())?.ExchangeRatesLatest();
return latestRates?.Rates;
