C# 中的 nested switch 语句函数

nested switch statements -语法

switch语句的语法如下所示:-

switch(ch1) {
   case 'A':
   Console.WriteLine("This A is part of outer switch" );
   
   switch(ch2) {
      case 'A':
         Console.WriteLine("This A is part of inner switch" );
         break;
      case 'B': /* inner B case code */
   }
   break;
   case 'B': /* outer B case code */
}

using System;

namespace DecisionMaking {
   class Program {
      static void Main(string[] args) {
         int a=100;
         int b=200;
         
         switch (a) {
            case 100: 
            Console.WriteLine("This is part of outer switch ");
            
            switch (b) {
               case 200:
               Console.WriteLine("This is part of inner switch ");
               break;
            }
            break;
         }
         Console.WriteLine("Exact value of a is : {0}", a);
         Console.WriteLine("Exact value of b is : {0}", b);
         Console.ReadLine();
      }
   }
} 

编译并执行上述代码时，将生成以下输出-
