Microsoft Silverlight will reach end of support after October 2021. Learn more.

Gets or sets the XML Schema definition (XSD) data type of the XML element generated by the XmlSerializer.

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

Syntax

'Declaration
Public Property DataType As String

public string DataType { get; set; }

Property Value

Type: System.String
An XML Schema data type, as defined by the World Wide Web Consortium (www.w3.org) document, XML Schema Part 2: Datatypes.

Exceptions

Exception	Condition
Exception	The XML Schema data type you have specified cannot be mapped to the.NET data type.

Remarks

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

XSD data type	.NET data type
anyURI	String
base64Binary	Array of Byte objects
boolean	Boolean
byte	SByte
date	DateTime
dateTime	DateTime
decimal	Decimal
double	Double
ENTITY	String
ENTITIES	String
float	Single
gDay	String
gMonth	String
gMonthDay	String
gYear	String
gYearMonth	String
hexBinary	Array of Byte objects
ID	String
IDREF	String
IDREFS	String
int	Int32
integer	String
language	String
long	Int64
Name	String
NCName	String
negativeInteger	String
NMTOKEN	String
NMTOKENS	String
normalizedString	String
nonNegativeInteger	String
nonPositiveInteger	String
NOTATION	String
positiveInteger	String
QName	XmlQualifiedName
duration	String
string	String
short	Int16
time	DateTime
token	String
unsignedByte	Byte
unsignedInt	UInt32
unsignedLong	UInt64
unsignedShort	UInt16

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

For every XML Schema type that is mapped to a string, apply the XmlElementAttribute with its DataType property set to the XML Schema type. This can change the serialization format, not only the schema for the member.

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

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