注解

下表列出了具有 their.NET 等效项的 XML 架构简单数据类型。

对于 XML 架构base64Binary和hexBinary数据类型，请使用结构数组Byte，并根据需要将SoapAttributeAttribute DataType集应用于“base64Binary”或“hexBinary”。对于 XML 架构time和date数据类型，请使用该DateTime类型，并将集DataType应用于SoapAttributeAttribute“date”或“time”。

对于映射到字符串的每个 XML 架构数据类型，请 SoapAttributeAttribute 将其 DataType 属性设置为 XML 架构数据类型。请注意，这不会更改序列化格式，仅更改成员的架构。

备注

该属性区分大小写，因此必须将其完全设置为 XML 架构数据类型之一。

备注

将二进制数据作为 XML 元素传递效率更高，然后将其作为 XML 属性传递。

有关 XML 架构数据类型的详细信息，请参阅名为 XML 架构第 2 部分的万维联盟文档：数据类型] (https://www.w3.org/TR/xmlschema-2/)。
