How to access a method of a dynamic component?

I have a number of components that implement an interface, for example:

@implements MyInterface@code {    public void MyMethod() { }}

On my page, I add these components dynamically using a ComponentMetadata class, for example:

private class ComponentMetadata{    public Type Type { get; set; }    public IDictionary<string, object> Parameters { get; set; }    public ComponentMetadata(Type type)    {        this.Type = type;    }}

And added as follows:

@{    var c = components.Single(x => x.Type == typeof(MyComponent));}<DynamicComponent Type="@c.Type" Parameters="@c.Parameters" />

Everything works as expected.

Now I would like to call MyMethod on each dynamic component that implements the interface. Is this possible, and if yes, how can I achieve this?
