Type dynamic along with Variables

I wanted to achieve following requirement not by using reflection 

class Customer
{

  public string Name {get;set;}

  public void Show()
  {
  }
}

Main Program
-------------
string propName = "Name"
string functionName  ="Show"

dynamic person = new Customer();
person.propName = "Some Value"
person.functionName()

How do i achieve it ?
