Gets the object associated with the specified (base class) type.
Item[Type, String]

Gets the object associated with the specified (base class) type. The member parameter specifies the base class member that is overridden.

Gets the object associated with the specified (base class) type.

public:
 property System::Xml::Serialization::SoapAttributes ^ default[Type ^] { System::Xml::Serialization::SoapAttributes ^ get(Type ^ type); };
public System.Xml.Serialization.SoapAttributes? this[Type type] { get; }
public System.Xml.Serialization.SoapAttributes this[Type type] { get; }

Default Public ReadOnly Property Item(type As Type) As SoapAttributes

Parameters

type
Type

The base class Type that is associated with the collection of attributes you want to retrieve.

Property Value

SoapAttributes

A SoapAttributes that represents the collection of overriding attributes.

Examples

The following example creates a SoapAttributeOverrides that is used to override the serialization of an instance of the Group class. The example also uses the Item[] property to retrieve the SoapAttributes that is used to specify how the serialization is being overridden.

Remarks

Use this overload to return a SoapAttributes that contains attributes that override a SoapAttributeAttribute, SoapElementAttribute, SoapIgnoreAttribute, or SoapEnumAttribute. You can also return a SoapAttributes that contains the override of a default value that uses a DefaultValueAttribute.

If the SoapAttributes contains a SoapTypeAttribute, you must use the overload that specifies only the overridden type.
