XmlRootAttribute.DataType Property

Gets or sets the XSD data type of the XML root element.

Namespace:  System.Xml.Serialization
Assembly:  System.Xml (in System.Xml.dll)

public string DataType { get; set; }

Property Value

Type: System.String
An XSD (XML Schema Document) data type, as defined by the World Wide Web Consortium (www.w3.org) document named "XML Schema: DataTypes".

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 XmlRootAttribute 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 XmlRootAttribute with the DataType set to "date" or "time".

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

NoteNote

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

NoteNote

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 World Wide Web Consortium (www.w3.org) document named "XML Schema Part 2: Datatypes".
