XmlAttributeAttribute.DataType Property

Definition

Gets or sets the XSD data type of the XML attribute generated by the XmlSerializer.

public:
 property System::String ^ DataType { System::String ^ get(); void set(System::String ^ value); };
public string DataType { get; set; }
member this.DataType : string with get, set
Public Property DataType As String

Property Value

An XSD (XML Schema Document) data type.

Examples

The following example applies the XmlAttributeAttribute to two members, and sets the DataType property set to different values.

public ref class Group
{
public:

   [XmlAttributeAttribute(DataType="string")]
   String^ Name;

   [XmlAttributeAttribute(DataType="base64Binary")]
   array<Byte>^Hex64Code;
};
public class Group{
   [XmlAttribute(DataType = "string")]
   public string Name;
    
   [XmlAttribute (DataType = "base64Binary")]
   public byte[] Hex64Code;
}
public class Group
    <XmlAttribute(DataType := "string")> _
    public Name As string 

    <XmlAttribute (DataType := "base64Binary")> _
    public Hex64Code () As byte 
End Class

Remarks

The following table lists the XSD simple data types with their.NET equivalents.

For the XSD base64Binary and hexBinary data types, use an array of Byte structures, and apply a XmlArrayItemAttribute with the DataType property set to "base64Binary" or "hexBinary", as appropriate. For the XSD time and date data types, use the DateTime type and apply the XmlAttributeAttribute with the DataType set to "date" or "time".

For every XSD type that is mapped to a string, apply the XmlAttributeAttribute with its DataType property set to the XSD type. However, this does not change the serialization format, only the schema for the member.

Note

The property is case-sensitive, so you must set it exactly to one of the XSD data types.

Note

Passing binary data as an XML element is more efficient than passing it as an XML attribute.

For more information about XML data types, see the XML Schema Part 2: DataTypes document from the World Wide Web Consortium.
