XmlRootAttribute.DataType Property

Definition

Namespace:

System.Xml.Serialization

Assembly:

System.Xml.ReaderWriter.dll

Source:

XmlRootAttribute.cs

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

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

String

An XSD (XML Schema Document) data type.

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 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.

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 World Wide Web Consortium document named XML Schema Part 2: Datatypes.
