如何在c＃中检查多个switch语句

Question

我需要检查switch语句中的多个语句来进行评估 像

 int a=5; 
 switch(a) 
 { 
     case 4,5:
         console.write("its from 4 to 5);
         break; 
 }

Answer 1

你想这样做：

case 4:
case 5:
//Code goes here.
break;

请记住，虽然C＃不允许摔倒，所以你不能这样做：

    case 4:
    //Do some stuff here
    //fall through to 5
    case 5:
    //Code goes here.
    break;

Answer 2

在c＃中你堆叠案例来做到这一点：

case 4:
case 5:
   //do something
   break;
case 6:
   //do something

等

Answer 3

这允许您为1个值执行多个案例。

int a=5; 
 switch(a) 
 { 
     case 4:
        // Do work here
        goto case 5;
     case 5:
         console.write("its from 4 to 5);
         break; 
 }

或

这是一个案例两个标签。

 switch(a) 
 { 
     case 4:
     case 5:
         console.write("its from 4 to 5);
         break; 
 }

Answer 4

这就是......

 int a=5; 
 switch(a) 
 { 
     case 4:
     case 5:
         console.write("its from 4 to 5);
         break; 
 }
