如何避免processContents="；“宽松”；在WCF WSDL中，来自实现IXmlSerializable的类？

我有一个以合同优先的方式编写的wcf服务。由于模式中的某些元素使用属性，因此我必须为此创建自定义序列化（使用

IXmlSerializable

）。下面是模式、类以及wsdl输出中的模式的片段

我的问题是，即使我为我的IXmlSerializable类呈现xsd，模式也不包括在wsdl中。它们只是用

processContents=“lax”

引用。对于我的服务的消费者来说，这似乎是一个问题，因为他们无法使用向导创建客户端

有人遇到过这个问题吗？是否仍有控制wsdl输出以避免这种情况。我在使用消息契约和数据契约时体验到了相同的行为

您正在从GetSchemaFile方法返回一个XmlSchemaComplexType，但是XmlSchemaProviderAttribute方法的契约规定您必须返回XmlQualifiedName。来自MSDN文档的备注部分，用于：

MethodName属性通过反射返回静态方法的名称。必须实现的方法必须采用单个参数，即XmlSchemaSet对象，该方法使用XmlSchema对象填充该对象。该方法还必须返回标识数据类型的XmlQualifiedName对象

---

原因很简单：假设您的模式中有几种类型，它如何知道它所反映的类代表哪一种类型？因此，通过返回一个XmlQualifiedName，实际上就是说这个类映射到这个模式中的这个类型。

谢谢。不知道我怎么会错过那个！不幸的是，当返回限定名称时，元数据端点在错误请求400错误中失败。。。
