Derived collection property not serialized in designer

I have class which derives from a collection which has a property MyString, i.e.



  public class CollectionItem
{
public bool MyBoolean { get; set; }

public int MyInteger { get; set; }
}

public class MyCollection : List<CollectionItem>
{
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
public string MyString { get; set; }

public MyCollection()
{
MyString = "Hello";
}
}


This collection is part of a simple DummyControl, i.e.



  public class DummyControl : System.Windows.Forms.Control
{
protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
e.Graphics.FillRectangle(System.Drawing.Brushes.Yellow, e.ClipRectangle);
}

public DummyControl()
{
MyCollection = new MyCollection();

for (int i = 0; i < 3; i++)
{
CollectionItem item = new CollectionItem();
item.MyInteger = i;
item.MyBoolean = i > 1;
MyCollection.Add(item);
}
}

[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public MyCollection MyCollection { get; set; }
}


When I put this DummyControl on a Windows Form, everything is serialized as expected to the Form Designer except the MyString property - this is what I get:



  // 
// dummyControl1
//
this.dummyControl1.Location = new System.Drawing.Point(66, 62);
collectionItem1.MyBoolean = false;
collectionItem1.MyInteger = 0;
collectionItem2.MyBoolean = false;
collectionItem2.MyInteger = 1;
collectionItem3.MyBoolean = true;
collectionItem3.MyInteger = 2;
this.dummyControl1.MyCollection.Add(collectionItem1);
this.dummyControl1.MyCollection.Add(collectionItem2);
this.dummyControl1.MyCollection.Add(collectionItem3);
this.dummyControl1.Name = "dummyControl1";
this.dummyControl1.Size = new System.Drawing.Size(338, 266);
this.dummyControl1.TabIndex = 0;
this.dummyControl1.Text = "dummyControl1";


Can anybody please tell me what more I have to do in order to have the MyString property serialized to the Form Designer?

          Default CodeDom collection serializer doesn't serialize properties of the collection. You can create a custom serializer by deriving from CodeDomSerializer. Then register the custom serializer for your class:



          [DesignerSerializer(typeof(MyCollectionSerializer), typeof(CodeDomSerializer))]
          public class MyCollection : List<CollectionItem>


          MyCollectionSerializer



          This serializer serializes MyString property of MyCollection:



          using System.CodeDom;
          using System.ComponentModel;
          using System.ComponentModel.Design.Serialization;
          public class MyCollectionSerializer : CodeDomSerializer
          {
          public override object Serialize(IDesignerSerializationManager manager, object value)
          {
          var baseSerializer = (CodeDomSerializer)manager.GetSerializer(
          typeof(MyCollection).BaseType, typeof(CodeDomSerializer));
          var statements = (CodeStatementCollection)baseSerializer.Serialize(manager, value);
          var property = TypeDescriptor.GetProperties(value)[nameof(MyCollection.MyString)];
          if (property.ShouldSerializeValue(value))
          {
          var targetObject = base.GetExpression(manager, value);
          var cpre = new CodePropertyReferenceExpression(targetObject, property.Name);
          var cpe = new CodePrimitiveExpression(property.GetValue(value));
          var cas = new CodeAssignStatement(cpre, cpe);
          statements.Add(cas);
          }
          return statements;
          }
          }


          Then MyString property will be serialized as well:



          // 
          // dummyControl1
          //
          ...
          this.dummyControl1.MyCollection.Add(collectionItem1);
          this.dummyControl1.MyCollection.Add(collectionItem2);
          this.dummyControl1.MyCollection.Add(collectionItem3);
          this.dummyControl1.MyCollection.MyString = "Hello";
          ...

          var cpe = new CodePrimitiveExpression(property.GetValue(value));
          var cas = new CodeAssignStatement(cpre, cpe);
          statements.Add(cas);
          }
          return statements;
          }
          }


          Then MyString property will be serialized as well:



          // 
          // dummyControl1
          //
          ...
          this.dummyControl1.MyCollection.Add(collectionItem1);
          this.dummyControl1.MyCollection.Add(collectionItem2);
          this.dummyControl1.MyCollection.Add(collectionItem3);
          this.dummyControl1.MyCollection.MyString = "Hello";
          ...

          Default CodeDom collection serializer doesn't serialize properties of the collection. You can create a custom serializer by deriving from CodeDomSerializer. Then register the custom serializer for your class:



          [DesignerSerializer(typeof(MyCollectionSerializer), typeof(CodeDomSerializer))]
          public class MyCollection : List<CollectionItem>


          MyCollectionSerializer



          This serializer serializes MyString property of MyCollection:



          using System.CodeDom;
          using System.ComponentModel;
          using System.ComponentModel.Design.Serialization;
          public class MyCollectionSerializer : CodeDomSerializer
          {
          public override object Serialize(IDesignerSerializationManager manager, object value)
          {
          var baseSerializer = (CodeDomSerializer)manager.GetSerializer(
          typeof(MyCollection).BaseType, typeof(CodeDomSerializer));
          var statements = (CodeStatementCollection)baseSerializer.Serialize(manager, value);
          var property = TypeDescriptor.GetProperties(value)[nameof(MyCollection.MyString)];
          if (property.ShouldSerializeValue(value))
          {
          var targetObject = base.GetExpression(manager, value);
          var cpre = new CodePropertyReferenceExpression(targetObject, property.Name);
          var cpe = new CodePrimitiveExpression(property.GetValue(value));
          var cas = new CodeAssignStatement(cpre, cpe);
          statements.Add(cas);
          }
          return statements;
          }
          }


          Then MyString property will be serialized as well:



          // 
          // dummyControl1
          //
          ...
          this.dummyControl1.MyCollection.Add(collectionItem1);
          this.dummyControl1.MyCollection.Add(collectionItem2);
          this.dummyControl1.MyCollection.Add(collectionItem3);
          this.dummyControl1.MyCollection.MyString = "Hello";
          ...
