C# 中的 SOAP 请求和响应
本文关键字：求和 响应 请求 SOAP 中的 | 更新日期: 2023-09-27 18:32:53
我为Soap XML请求编写了c#代码，我已经验证了生成XML类的代码。
我的问题是如何使用 c# 代码发送请求和接收响应。
请善待我的简单或基本错误，因为我是 XML 的新手，但您的帮助将不胜感激。

请告诉我如何使用上面的代码发送请求并接收来自WCF服务的响应。
即使我添加了 wsdl 引用，但我不知道如何在下面的行中传递 XmlElement[]。
serviceReference.getDetail(ref XmlElement[] Any(;
下面是引用类中的一个方法。

@CodeCaster我尝试了您的代码： var documentToSend = new XmlDocument((; 待办事项：添加您喜欢
的所有元素 using (XmlTextWriter xmlRequestWriter = new XmlTextWriter(@"C：/Unipass/Request.xml"， Encoding.UTF8(( { xmlRequestWriter.WriteStartDocument((; xmlRequestWriter.WriteStartElement("ce：message"(; xmlRequestWriter.WriteEndElement((; xmlRequestWriter.WriteEndDocument((; xmlRequestWriter.Flush((; documentToSend.Save(xmlRequestWriter(; 创建一个将根消息节点作为唯一元素的数组。 var xmlToSend = new XmlElement[] { documentToSend.DocumentElement };xmlToSend = null
}可能是我做错了，你能告诉我为什么 xmlToSend 为空吗？
您似乎正在手动编写代码以将消息序列化为 SOAP/XML。SOAP 请求示例是一个实际的实例文档，而不是 WSDL，是吗？这是 WCF 为您执行的操作之一 - 您不需要生成自己的 SOAP 消息。
在 WCF 中，您专注于要传输的对象类型和要支持的操作。然后，WCF 会为您完成 SOAP 序列化的所有繁重工作。这确实是WCF的重点。
很难从示例 SOAP 消息中破译您到底要做什么，因此我建议查看一个简单的 WCF 示例之一，例如从此处开始
http://msdn.microsoft.com/en-us/library/vstudio/ms751514(v=vs.90(.aspx
使用 wsHttpBinding 或 basicHttpBinding 启动并运行一个简单的绑定(这些是 WCF 中的 SOAP 绑定(。然后使用 Fiddler 或类似方法捕获 HTTP 请求，并查看 WCF 在 SOAP 信封生成方面为您做了什么。
然后，您应该能够将其转换为您自己的案例。
鉴于生成的方法签名getDetailRequest(System.Xml.XmlElement[] Any)，WCF 的代理生成器似乎无法从提供的 WSDL/XSD 创建类。像 SoapUI 这样的工具对 WSDL 有什么看法？
解决此问题的一种方法是手动生成消息，这只是<ce:message>..</ce:message>块。调用服务方法时，WCF 会将其包装在适当的 SOAP 信封中。
你必须在XmlDocument类中玩一玩，但我认为这样的事情可以做到：
// Create an XmlDocument and fill it
var documentToSend = new XmlDocument();
// TODO: add all elements you like
// Create an array with the root message node as only element.
var xmlToSend = new XmlElement[] { documentToSend.DocumentElement };
// Call the service.
var response = serviceReference.getDetail(xmlToSend);
另一种方法是在 C# 中手动重新创建请求类，并在发送请求时将其实例填充并序列化为 XML。最终的方法是修复 XML，以便添加服务引用 (SvcUtil( 可以从服务的元数据生成类。
至于您的编辑，您不是将 XML 元素写入documentToSend，而是将它们写入您的文件。
