XmlSerializerVersionAttribute Class


Signifies that the code was generated by the serialization infrastructure and can be reused for increased performance, when this attribute is applied to an assembly.

public ref class XmlSerializerVersionAttribute sealed : Attribute
public sealed class XmlSerializerVersionAttribute : Attribute
type XmlSerializerVersionAttribute = class
    inherit Attribute
Public NotInheritable Class XmlSerializerVersionAttribute
Inherits Attribute


The .NET Framework XML serialization infrastructure dynamically generates derivations of XmlSerializer that are optimized to serialize user-defined types. The serializers are stored in assemblies that can be reused for efficient serialization.

The XmlSerializerVersionAttribute attribute stores version information about the parent assembly for which a set of serializers is generated. Later, when the XmlSerializer constructor is called, the infrastructure attempts to locate the pre-generated assembly. If the infrastructure finds an assembly with a matching name, the assembly is loaded and the infrastructure checks XmlSerializerVersionAttribute for a match between the found assembly's version and the current version of the parent assembly. If the version does not match, the found assembly is not used. Instead, a temporary assembly is generated for the serialization.



Initializes a new instance of the XmlSerializerVersionAttribute class.


Initializes a new instance of the XmlSerializerVersionAttribute class for the specified type.



Gets or sets the common language runtime (CLR) namespace of the assembly.


Gets or sets the identity of the parent assembly.


Gets or sets the type that the serializer operates on.


When implemented in a derived class, gets a unique identifier for this Attribute.

(Inherited from Attribute)

Gets or sets the assembly's version number.



Returns a value that indicates whether this instance is equal to a specified object.

(Inherited from Attribute)

Returns the hash code for this instance.

(Inherited from Attribute)
