XmlElementAttribute::Type Property

 

Gets or sets the object type used to represent the XML element.

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

public:
property Type^ Type {
	Type^ get();
	void set(Type^ value);
}

Property Value

Type: System::Type^

The Type of the member.

Use the Type property to specify a derived type for a field or property.

If a field or property returns an ArrayList, you can apply multiple instances of the XmlElementAttribute to the member. For each instance, set the Type property to a type of object that can be inserted into the array.

The following example uses the Type property to specify a derived object for an XmlElementAttribute. The example also applies three instances of the XmlElementAttribute to a field that returns an ArrayList. Each instance specifies a type allowed in the field.
