c# - 如何从 SOAP 响应 XML 创建 WCF 消息对象

Question

为了对处理 WCF 响应的类进行单元测试，我使用 Message.ToString() 获取了一个实际的消息响应，这样我就不必实际进行 WCF 调用(因此使其成为集成测试而不是单元测试)。我如何根据来自 Message.ToString() 输出的 SOAP XML 重新构造 Message 对象，或者它甚至可能吗？我不知道哪个 Message.CreateMessage() 重载可以解决这种情况。

这是 Message.ToString() 的结果:

那么，我如何从中构建消息？

Answer 1

如果您有消息的整个信封，则可以使用重载 Message.CreateMessage(XmlDictionaryReader, int, MessageVersion) 创建 Message 对象.使用与此类似的代码在消息的内容上创建一个 XmlDictionaryReader:

var bytes = Encoding.UTF8.GetBytes(theMessageString);
var reader = XmlDictionaryReader.CreateTextReader(bytes, XmlDictionaryReaderQuotas.Max);

现在，您的消息有一些时间戳，已加密并签名。有可能一旦传给WCF，就失效了...
