如何在.NET Core 3.1中以编程方式从WSDL定义文件中提取模式？

问题描述

我有一个如下所述的WSDL文件，通过编程需要使用c＃.net core 3.1和每个架构部分的 targetNamespace 从下面的WSDL中读取架构部分，以将其传递给以下XmlReaderSettings。

XmlReaderSettings settings = new XmlReaderSettings();
settings.Schemas.Add("targetNamespace from Schema1,"schema1");
settings.Schemas.Add("targetNamespace from Schema2,"schema2");
settings.Schemas.Add("targetNamespace from Schema3,"schema3");

更新1 这是我的代码，出现以下错误：W3C XML Schema的根元素应该是，其命名空间应该是'w3.org/2001/XMLSchema'

string xml = File.ReadAllText("SingleWSDL.xml");
StringReader sReader = new StringReader(xml);
XmlReader xReader = XmlReader.Create(sReader);
xReader.ReadToFollowing("schema","schemas.xmlsoap.org/wsdl/");
XmlReaderSettings settings = new XmlReaderSettings();
settings.Schemas.Add("w3.org/2001/XMLSchema",xReader); 
settings.ValidationType = ValidationType.Schema;
XmlReader reader = XmlReader.Create("Test6.xml",settings);
XmlDocument document = new XmlDocument();
document.Load(reader);document.Validate(eventHandler);

解决方法

您缺少带有ReadToFollowing的名称空间：

           string xml = File.ReadAllText("SingleWSDL.xml");
            StringReader sReader = new StringReader(xml);
            XmlReader xReader = XmlReader.Create(sReader);
            xReader.ReadToFollowing("schema","http://schemas.xmlsoap.org/wsdl/");

            XmlReaderSettings settings = new XmlReaderSettings();
            settings.Schemas.Add("w3.org/2001/XMLSchema",xReader);
