The XmlSerializerAssemblyAttribute type exposes the following members.

Constructors
  NameDescription
Public method XmlSerializerAssemblyAttributeInitializes a new instance of the XmlSerializerAssemblyAttribute class.
Public method XmlSerializerAssemblyAttribute(String)Initializes a new instance of the XmlSerializerAssemblyAttribute class with the specified assembly name.
Public method XmlSerializerAssemblyAttribute(String, String)Initializes a new instance of the XmlSerializerAssemblyAttribute class with the specified assembly name and location of the assembly.

Properties
  NameDescription
Public property AssemblyNameGets or sets the name of the assembly that contains serializers for a specific set of types.
Public property CodeBaseGets or sets the location of the assembly that contains the serializers.
Public property TypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Top
Methods
  NameDescription
Public method EqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Public method GetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public method GetTypeGets the Type of the current instance. (Inherited from Object.)
Public method IsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public method MatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public method ToStringReturns a string that represents the current object. (Inherited from Object.)

Explicit Interface Implementations
  NameDescription
Explicit interface implemetation Private method _AttributeGetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeGetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeGetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetation Private method _AttributeInvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

Remarks

Use the XmlSerializerAssemblyAttribute to increase the performance of a Web service client application.

A typical method of using this attribute is as follows:

  1. Create a client proxy for a Web service.

  2. Open the machine.config file.

  3. Under the system.diagnostics element, add a value under the <switches> element to keep the compiled files:

    <system.diagnostics>
       <switches>
          <add name="XmlSerialization.Compilation" value="4"/>
       </switches>
    </system.diagnostics>
  4. Compile the proxy.

  5. Run the proxy application.

  6. Open a command window and navigate to the \Temp directory used by the XmlSerializer to cache files.

    cd %temp%
  7. Find the last file created using the dir command with the /OD switch.

    dir *.vb /OD 
  8. Compile the file into an assembly. Name the assembly.

  9. Edit the original proxy code by applying the XmlSerializerAssemblyAttribute to the class. Specify the assembly name, as shown in the following C# code.

    [XmlSerializerAssemblyAttribute(AssemblyName="hello.serializer")]
    public class Hello: System.Web.Services.Protocols.SoapHttpClientProtocol {
       // Proxy code not shown.
    }
<XmlSerializerAssemblyAttribute(AssemblyName:="hello.serializer")> _
Public Class Hello
Implements System.Web.Services.Protocols.SoapHttpClientProtocol 
   ' Proxy code not shown.
End Class
