When I generate ac# class from a xsd schema with xsd.exe I find this behaivor a bit wierd.
My element:
<xs:element name="InvoiceNo" type="xs:integer"/>
is generated to:
[System.Xml.Serialization.XmlElementAttribute(DataType="integer", Order=5)]
public string InvoiceNo
{
...
}
Why is that property not generated as an int instead of string ?
This behavior is by design :
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
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" />
Here's a detailed list of the data types defined in the XML Schema Definition standard.
