Given two classes, Class1 and Class2, where Class2 is inherited from Class1, and a property Prop1, reading the DeclaringType of the PropertyInfo for Prop1 and comparing it to the full class name of Class2 will help determine whether Prop1 is inherited or not. If Prop1 is inherited, the full class name will not be the same as the the full class name of Class2.

                Class2 class2 = new Class2();
                Type t = class2.GetType();

                PropertyInfo[] pis = t.GetProperties();
                string DeclaringType = pis.DeclaringType.ToString();
                for (int i = 0; i < pis.Length; i++)
                {

                  PropertyInfo pi = (PropertyInfo)pis.GetValue(i); // Walk the property list
                  string DeclaringType = pi.DeclaringType.ToString();
                  if (DeclaringType != t.FullName) {
                      //  pi is referencing a property that is inherited
                  }

                }
