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.

System.Object
  System.Attribute
    System.Xml.Serialization.XmlSerializerVersionAttribute

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

[AttributeUsageAttribute(AttributeTargets.Assembly)]
public sealed class XmlSerializerVersionAttribute : Attribute

The XmlSerializerVersionAttribute type exposes the following members.

  NameDescription
Public methodXmlSerializerVersionAttribute()Initializes a new instance of the XmlSerializerVersionAttribute class.
Public methodXmlSerializerVersionAttribute(Type)Initializes a new instance of the XmlSerializerVersionAttribute class for the specified type.

  NameDescription
Public propertyNamespaceGets or sets the common language runtime (CLR) namespace of the assembly.
Public propertyParentAssemblyIdGets or sets the identity of the parent assembly.
Public propertyTypeGets or sets the type that the serializer operates on.
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Public propertyVersionGets or sets the assembly's version number.

  NameDescription
Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

  NameDescription
Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides access to properties and methods exposed by an object. (Inherited from 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.
