基础：继承之Object类型的int 重点看CompareTo

   1:   static void ObjectFunctionality() {

   2:              int a = 12;

   3:              Console.WriteLine("=> System.Object Functionality:");

   4:              Console.WriteLine("12.GetHashCode()={0}",a.GetHashCode());

   5:              Console.WriteLine("12.Equals(23)={0}",a.Equals(23));

   6:              Console.WriteLine("12.GetType()={0}",a.GetType());

   7:              Console.WriteLine("12.GetTypeCode()={0}",a.GetTypeCode());

   8:              Console.WriteLine("12.ToString()={0}",a.ToString());

   9:              Console.WriteLine("12.CompareTo(11)={0}",a.CompareTo(11));

  10:              Console.WriteLine("12.CompareTo(23)={0}", a.CompareTo(23));

  11:              Console.WriteLine("12.CompareTo(12)={0}", a.CompareTo(12));

  12:          }

    结果：

         

 

数值数据类型的成员：

   1:     static void DataTypeFunctionality() {

   2:              Console.WriteLine("Max of int:{0}",int.MaxValue);

   3:              Console.WriteLine("Min of int:{0}",int.MinValue);

   4:              Console.WriteLine("Max of double:{0}",double.MaxValue);

   5:              Console.WriteLine("Min of double:{0}",double.MinValue);

   6:              Console.WriteLine("double.PositiveInfinity,double的正无穷大:{0}",double.PositiveInfinity);

   7:              Console.WriteLine("double的负无穷:{0}",double.NegativeInfinity);

   8:              Console.WriteLine("大于零的最大double的值",double.Epsilon);

   9:   

  10:          }

结果：
