Syntax

In C#Nested ifThe syntax of the statement:

if( boolean_expression 1)
{
   /* 当布尔表达式 1 为真时执行 */
   if(boolean_expression 2)
   {
      /* 当布尔表达式 2 为真时执行 */
   }

Example

Example

using System;

namespace DecisionMaking
{
   
    class Program
    {
        static void Main(string[] args)
        {

            //* Local variable definitions */
            int a = 100;
            int b = 200;

            /* Check boolean condition */
            if (a == 100)
            {
                /* If the condition is true, then check the condition below */
                if (b == 200)
                {
                    /* If the condition is true, output the following statement */
                    Console.WriteLine("The value of a is 100, and the value of b is 200");
                }
            }
            Console.WriteLine("The exact value of a is {0}", a);
            Console.WriteLine("The exact value of b is {0}", b);
            Console.ReadLine();
        }
    }
}

When the above code is compiled and executed, it produces the following result:

a 的值是 100，且 b 的值是 200
a 的准确值是 100
b 的准确值是 200
