csharpprogrammingserver side programming
使用 C# 中的 CompareTo() 方法比较两个枚举。
该方法返回以下任意值 −
- 小于零:源值小于目标值
- 零:源值等于目标值
- 大于零:源值大于目标值
示例
using System;
class Program {
enum Products { HardDrive = 0, PenDrive = 4, Keyboard = 8 };
static void Main() {
Products prod1 = Products.HardDrive;
Products prod2 = Products.PenDrive;
Products prod3 = Products.Keyboard;
Console.WriteLine("Stock for {0} is more than {1}?", prod3, prod2);
Console.WriteLine( "{0}{1}",prod3.CompareTo(prod2) > 0 ? "Yes" : "No", Environment.NewLine );
}
}
输出
Stock for Keyboard is more than PenDrive? Yes
