C# WCF客户端asp.net core3.1中的XML响应分析异常

我使用

connected service

功能将一个soap wcf web服务连接到我的asp.net core 3.1，并生成

Reference.cs

文件，但每当我尝试调用一个wcf web服务方法时，我都会遇到xml解析错误。我没有控制wcf web服务，因此无法更改响应xml

以下是完整的堆栈跟踪：

我不确定这里的问题是什么，所以我尝试将我认为与此问题有关的大部分内容包括在内

---

我试图更改几个属性和参数，但得到的最佳结果是一个空的输出对象。这是生成错误的类和xml属性的错误吗？如何修复解析过程？

这可能是WCF服务的问题，您可以尝试使用.net framework调用此服务。@DingPeng我也怀疑，但我在.net framework中也得到了相同的结果。那么这应该是服务器端问题，您需要检查服务器端。您也可以尝试使用通道工厂调用服务。@DingPeng我最终使用了

ClientMessageInspectors

，并在反序列化之前手动解析和更改回复XML消息。
