Question

我尝试使用ControlDesigner创建自定义控件。我找到了一种在http://code.msdn.microsoft.com/WinFormsCustomCtrl使用带有ClientProfile的ControlDesinger的方法，但是要使用这个方法，想要使用的项目必须手动添加Control的Design-Project dll。

是否可以将Design-Project dll作为嵌入式资源添加到我的控件中，或者是否有办法自动将Design-Project dll添加到想要使用我的控件的项目中？

项目控制：

namespace NControl
{
    [Designer("NDesign.MyControlDesigner, NDesign")]
    public class MyControl : Control
    {
        static MyControl()
        {
            TypeDescriptor.AddProvider(new DynamicDesignerProvider(TypeDescriptor.GetProvider(typeof(object))), typeof(object));
        }
    }

    internal sealed class DynamicDesignerProvider : TypeDescriptionProvider
    {
        internal DynamicDesignerProvider(TypeDescriptionProvider parent) : base(parent) { }

        public override ICustomTypeDescriptor GetTypeDescriptor(Type objectType, object instance)
        {
            if (objectType.Assembly == typeof(MyControl).Assembly)
            {
                IComponent component = instance as IComponent;
                if (component != null && component.Site != null)
                {
                    return new DesignerAttributeTypeDescriptor(base.GetTypeDescriptor(objectType, instance), component);
                }
            }
            return base.GetTypeDescriptor(objectType, instance);
        }
    }

    internal sealed class DesignerAttributeTypeDescriptor : CustomTypeDescriptor
    {
        IServiceProvider _provider;

        internal DesignerAttributeTypeDescriptor(ICustomTypeDescriptor parent, IComponent component)
            : base(parent)
        {
            if (component != null)
            {
                _provider = component.Site;
            }
        }

        public override AttributeCollection GetAttributes()
        {
            AttributeCollection ac = base.GetAttributes();
            List<Attribute> attrs = new List<Attribute>();
            foreach (Attribute attr in ac)
            {
                DesignerAttribute dattr = attr as DesignerAttribute;
                if (dattr != null && dattr.DesignerBaseTypeName.StartsWith("System.ComponentModel.Design.IDesigner"))
                {
                    ITypeResolutionService trs = null;
                    if (_provider != null)
                    {
                        trs = (ITypeResolutionService)_provider.GetService(typeof(ITypeResolutionService));
                    }

                    if (trs != null && trs.GetType(dattr.DesignerTypeName) == null)
                    {
                        DesignerAttribute da = new DesignerAttribute("System.Windows.Forms.Design.ControlDesigner, System.Design");
                        attrs.Add(da);
                        continue;
                    }
                }

                attrs.Add(attr);
            }
            return new AttributeCollection(attrs.ToArray());
        }
    }
}

项目设计：

namespace NDesign
{
    public class MyControlDesigner : ParentControlDesigner
    {
        // My DesignCode
    }
}

我认为这篇文章（http://msdn.microsoft.com/en-us/library/ee849818.aspx）会有所帮助。

C＃：ControlDesigner DLL作为嵌入式资源，有可能吗？
