问题描述
当我使用 xsd.exe 从 xsd 架构生成 c# 类时,我发现这种行为有点奇怪.
When I generate a c# class from a xsd schema with xsd.exe I find this behaivor a bit wierd.
我的元素:
<xs:element name="InvoiceNo" type="xs:integer"/>
生成到:
[System.Xml.Serialization.XmlElementAttribute(DataType="integer", Order=5)]
public string InvoiceNo
{
...
}
为什么该属性没有生成为 int 而不是 string?
Why is that property not generated as an int instead of string?
推荐答案
这种行为是设计使然一个>:
xs:integer
类型被指定为没有大小写的数字受限于它的大小.因此,XML 序列化和验证将其映射到 System.Int32 类型.相反,XML 序列化将 xs:integer
映射到字符串,而验证将其映射到Decimal 类型,远大于.NET 框架
The
xs:integer
type is specified as a number with no upper or lower bound on its size. For this reason, neither XML serialization nor validation map it to the System.Int32 type. Instead, XML serialization maps thexs:integer
to a string while validation maps it to the Decimal type that is much larger than any of the integer types in the .NET Framework
使用 xs:int
,它是一个有符号的 32 位整数,具有 Xsd.exe 将其映射到 System.Int32:
Use xs:int
, which is a signed 32-bit integer, to have Xsd.exe map it to a System.Int32:
<xs:element name="InvoiceNo" type="xs:int" />
这里是 XML 架构定义标准中定义的数据类型的详细列表.
Here's a detailed list of the data types defined in the XML Schema Definition standard.
