IDesignerSerializationManager Interface

Provides an interface that can manage design-time serialization.

Namespace:  System.ComponentModel.Design.Serialization
Assembly:  System (in System.dll)

public interface IDesignerSerializationManager : IServiceProvider

A designer can utilize IDesignerSerializationManager to access services useful to managing design-time serialization processes. For example, a class that implements the designer serialization manager can use this interface to create objects, look up types, identify objects, and customize the serialization of particular types.

The following example illustrates how to use IDesignerSerializationManager to serialize and deserialize Code DOM statements.

using System;
using System.CodeDom;
using System.ComponentModel;
using System.ComponentModel.Design;
using System.ComponentModel.Design.Serialization;
using System.Drawing;
using System.Windows.Forms;

namespace CodeDomSerializerSample
    internal class MyCodeDomSerializer : CodeDomSerializer {
        public override object Deserialize(IDesignerSerializationManager manager, object codeObject) {
            // This is how we associate the component with the serializer.
                CodeDomSerializer baseClassSerializer = (CodeDomSerializer)manager.
                GetSerializer(typeof(MyComponent).BaseType, typeof(CodeDomSerializer));

            /* This is the simplest case, in which the class just calls the base class
                to do the work. */ 
            return baseClassSerializer.Deserialize(manager, codeObject);

        public override object Serialize(IDesignerSerializationManager manager, object value) {
            /* Associate the component with the serializer in the same manner as with
                Deserialize */
            CodeDomSerializer baseClassSerializer = (CodeDomSerializer)manager.
                GetSerializer(typeof(MyComponent).BaseType, typeof(CodeDomSerializer));

            object codeObject = baseClassSerializer.Serialize(manager, value);

            /* Anything could be in the codeObject.  This sample operates on a
                CodeStatementCollection. */ 
            if (codeObject is CodeStatementCollection) {
                CodeStatementCollection statements = (CodeStatementCollection)codeObject;

                // The code statement collection is valid, so add a comment.
                string commentText = "This comment was added to this object by a custom serializer.";
                CodeCommentStatement comment = new CodeCommentStatement(commentText);
                statements.Insert(0, comment);
            return codeObject;

    [DesignerSerializer(typeof(MyCodeDomSerializer), typeof(CodeDomSerializer))]
    public class MyComponent : Component {
        private string localProperty = "Component Property Value";
        public string LocalProperty {
            get {
                return localProperty;
            set {
                localProperty = value;
