Remarks

You can implement a custom CodeDomSerializer to control the generation of component initialization code for a type of component at design time.

To implement a custom CodeDomSerializer for a type, you must:

  1. Define a class that derives from CodeDomSerializer.

  2. Implement method overrides for serialization or deserialization methods. (See the information below for details.)

  3. Associate your custom CodeDomSerializer implementation with a type of component using a DesignerSerializerAttribute.

To implement a serialization method for generating configuration code for a component:

  1. Within a class that derives from CodeDomSerializer, override an appropriate serialization or deserialization method of the base class.

  2. If you want the default serializer to generate code statements that perform the default component configuration, you must obtain and call the base serializer for the component. To obtain the base serializer for the component, call the GetSerializer method of the IDesignerSerializationManager passed to your method override. Pass the GetSerializer method the type of the component to serialize the configuration of, along with the base type of serializer you are requesting, which is CodeDomSerializer. Call the method of the same name you are overriding on the base serializer, using the IDesignerSerializationManager and object passed to your method override. If you are implementing the Serialize method, the Serialize method of the base serializer will return an object. The type of this object depends on the type of base serializer which depends on the type of component you are serializing the values of. If you are implementing the SerializeEvents, SerializeProperties, or SerializePropertiesToResources method, you must create a new CodeStatementCollection to contain the generated code statements, and pass it to the method.

  3. If you have called a base serializer method, you will have a CodeStatementCollection that contains the statements to generate to initialize the component. Otherwise you should create a CodeStatementCollection. You can add CodeStatement objects representing statements to generate in the component configuration code to this collection.

  4. Return the CodeStatementCollection that represents the source code to generate to configure the component.
