在MyClass上创建一个暴露SubClass.Property的属性。像这样：

Create a property on MyClass that exposes the SubClass.Property. Like so:

public class MyClass
{
   private SubClass _mySubClass;

   public MyClass(SubClass subClass)
   {
      _mySubClass = subClass;
   }

   public PropertyType Property
   {
      get { return _subClass.Property;}
   }   
}
