注解

Detail可以使用接受Detail值的类构造函数之一设置 属性。

属性 Detail 用于提供与 SOAP 请求的 元素相关的 Body 特定于应用程序的错误详细信息。 根据 SOAP 规范，如果由于 SOAP 请求的 元素而无法处理 Body 客户端请求而发生错误， Detail 则必须设置 属性。 如果 SOAP 请求的标头条目中发生错误，则必须引发 ， SoapHeaderException以便在 SOAP 标头中返回错误详细信息。 如果由于 元素的 Body 处理而未发生错误，则 Detail 不得设置 属性。

在为 Detail 属性生成 时XmlNode，Name可以使用 的 DetailElementName 和 Namespace 属性来确保与 SOAP 规范的一致性。

detail 元素的所有直接子元素称为详细信息条目，每个详细信息项在 detail 元素中编码为独立元素。
