本示例演示IF语句的使用,比较两个数值的大小,并输出结果。
using System; namespace a { class Program { public static void Main(string[] args) { string comparison; Console.WriteLine("Enter a number:"); double var1=Convert.ToDouble(Console.ReadLine()); Console.WriteLine("Enter another number:"); double var2=Convert.ToDouble(Console.ReadLine()); if(var1<var2) comparison="less than"; else { if(var1==var2) comparison="equal to"; else comparison="greater than"; } Console.WriteLine("The first number is {0} the second number.",comparison); Console.ReadKey(); } } }
