比较运算符基本上用于比较两个操作数。
比较运算符基于比较返回真或者假值。
比较运算符使用某些条件语句和循环构造，例如循环，if ..else。

C#比较运算符例子

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace Comparison_Operator

{

    class Program

    {

        static void Main(string[] args)

        {

            int num1, num2;

            //Accepting two inputs from the user

            Console.Write("Enter first number\t");

            num1 = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter second number\t");

            num2 = Convert.ToInt32(Console.ReadLine());

 

            //Processing comparison

            //Check whether num1 is greater than or not

            if (num1 > num2)

            {

                Console.WriteLine("{0} is greater than {1}", num1, num2);

            }

            //Check whether num2 is greater than or not

            else if (num2 > num1)

            {

                Console.WriteLine("{0} is greater than {1}", num2, num1);

            }

            else

            {

                Console.WriteLine("{0} and {1} are equal", num1, num2);

            }

            Console.ReadLine();

        }

    }

}
