如何在c＃中檢查多個switch語句

Question

我需要檢查switch語句中的多個語句來評估

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

Answer 1

你想做：

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

請記住，雖然C＃不允許通過，所以你不能這樣做：

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

Answer 2

在c＃中你堆棧的情況是這樣的：

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

等等

Answer 3

這允許您為1個值執行多個案例。

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

要么

這是一個案例兩個標簽。

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

Answer 4

這是怎么回事..

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