问题描述

我很困惑如何在开关中限制穿透。例如

以下作品:


string switch_test =" a" ;;

开关(switch_test)

{

case" a":

case" b":

case" c":

doSomething(a);

休息;

}


但以下不起作用:

string switch_test =" a" ;;

switch(switch_test)

{

case" a":

if(< some test>)

break;

case" b":

case" c":

doSomething(a);

}

为什么会这样?

I''m confused as to how fallthrough is limited in switch. For example
the following works:

string switch_test = "a";
switch (switch_test)
{
case "a":
case "b":
case "c":
doSomething(a);
break;
}

but the following does not work:
string switch_test = "a";
switch (switch_test)
{
case "a":
if (<some test>)
break;
case "b":
case "c":
doSomething(a);
}
why is that?
