SoapTypeAttribute Constructor ()

 

Initializes a new instance of the SoapTypeAttribute class.

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

public:
SoapTypeAttribute()

Create a SoapTypeAttribute when overriding the serialization of a type. Assign the object to the SoapType property of a SoapAttributes and add the SoapAttributes to a SoapAttributeOverrides. See the SoapAttributeOverrides class overview for more details about overriding SOAP serialization.

The following example serializes a class named Group. The SoapTypeAttribute is applied to the class with the TypeName set to "SoapGroupType". The SoapTypeAttribute is also overridden, changing the TypeName to "Team". Both versions are serialized, resulting in two files: SoapType.xml and SoapType2.xml.
