XmlTextAttribute Class


The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

Indicates to the XmlSerializer that the member must be treated as XML text when the class that contains it is serialized or deserialized.

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


[AttributeUsageAttribute(AttributeTargets::Property | AttributeTargets::Field | AttributeTargets::Parameter | AttributeTargets::ReturnValue)]
public ref class XmlTextAttribute : Attribute


Initializes a new instance of the XmlTextAttribute class.


Initializes a new instance of the XmlTextAttribute class.


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


Gets or sets the type of the member.


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)


This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)


Returns the hash code for this instance.(Inherited from Attribute.)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Creates a shallow copy of the current Object.(Inherited from Object.)


Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute::GetIDsOfNames(Guid%, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute::GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute::Invoke(UInt32, Guid%, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

The XmlTextAttribute belongs to a family of attributes that controls how the XmlSerializer serializes and deserializes an object (through its Serialize and Deserialize methods). For a complete list of similar attributes, see Attributes That Control XML Serialization.

Only one instance of the XmlTextAttribute class can be applied in a class.

You can apply the XmlTextAttribute to public fields and public read/write properties that return primitive and enumeration types.

You can apply the XmlTextAttribute to a field or property that returns an array of strings. You can also apply the attribute to an array of type Object but you must set the Type property to string. In that case, any strings inserted into the array are serialized as XML text.

The XmlTextAttribute can also be applied to a field that returns an XmlNode or an array of XmlNode objects.

By default, the XmlSerializer serializes a class member as an XML element. However, if you apply the XmlTextAttribute to a member, the XmlSerializer translates its value into XML text. This means that the value is encoded into the content of an XML element.

The XML Schema Definition Tool (Xsd.exe) occasionally generates the XmlTextAttribute when creating classes from an XML Schema definition (XSD) file. This occurs when the schema contains a complexType with mixed content; in that case, the corresponding class contains a member that returns a string array to which the XmlTextAttribute is applied. For example, when the Xml Schema Definition tool processes this schema:

<xs:schema attributeFormDefault="qualified" elementFormDefault="qualified" targetNamespace="" 
  <xs:element name="LinkList" type="LinkList" />
  <xs:complexType name="LinkList" mixed="true">
      <xs:element minOccurs="1" maxOccurs="1" name="id" type="xs:int" />
      <xs:element minOccurs="0" maxOccurs="1" name="name" type="xs:string" />
      <xs:element minOccurs="0" maxOccurs="1" name="next" type="LinkList" />

the following class is generated (extra spaces and remarks have been removed):

No code example is currently available or this language may not be supported.
