Call a method on a dynamic object by name

Question

I'm trying to create a "wrapper" around a dynamic object so I can keep method names on dynamic object matching the names of the methods in the wrapping class.

What I need to do is provide the helper a dynamic object, and the name of the method i want to call on it (via [CallerMemberName]), and the args for the call. I can't figure out how to invoke the call on the dynamic object. How can I do this?

class Program
{
    static void Main(string[] args)
    {
        var dyn = new ClassWithDynamicProperty();
        dyn.SendMessage("test");
        Console.ReadKey();
    }
}

public class ExampleDynamicClass
{
    public void SendMessage(string msg)
    {
        Console.WriteLine(msg);
    }
}

public class ClassWithDynamicProperty
{
    public ClassWithDynamicProperty()
    {
        MyDynObject = new ExampleDynamicClass();
    }

    public dynamic MyDynObject { get; set; }

    public void SendMessage(string theMessage)
    {
        //i want to replace this:
        MyDynObject.SendMessage(theMessage);
        //with this:
        DynamicHelper.CallDynamic(MyDynObject, new object[] { theMessage });
    }
}

public static class DynamicHelper
{
    public static void CallDynamic(dynamic source, object[] args, [CallerMemberName]string methodName = null)
    {
        //source.methodName(args); How can i invoke this?
    }
}

Turns out it's not that hard after all. I didn't know if normal reflection would work with dynamic types. All resources I found for dynamic objects involved overriding TryInvokeMember, which wasn't an option. Here's missing code:

var method = ((object)dynamicObject).GetType().GetMethod(methodName);
method.Invoke(dynamicObject, args);
