具有一个Int类型的多个案例的枚举，如何按其rawValue打印案例名称？
class Foo {
var number: Int = 0; private set
fun increment() {
++number;
}
}
我正在通过rawValue访问枚举：
public enum TestEnum : UInt16{
case ONE = 0x6E71
case TWO = 0x0002
case THREE = 0x0000
}
现在，我还想在十六进制值之后打印“一”。
我知道问题：How to get the name of enumeration value in Swift? 但这有所不同，因为我想通过案例原始值而不是枚举值本身来确定案例名称。
所需的输出：
命令类型= 0x6E71，一个

由于枚举类型不是<div class="widget-stencilbar-livescore"
data-module="stencilbar/livescore"
>
<div class="widget-stencilbar-livescore__header">
<h1 class="widget-stencilbar-livescore__title">
{{ $headline }}
</h1>
@include('widgets.switch.index', [
'default' => trans('widgets/stencilbar/livescore/index.competitions'),
'alt' => trans('widgets/stencilbar/livescore/index.kickoff')
])
</div>
<div class="widget-stencilbar-livescore__icons">
<div class="widget-stencilbar-livescore__icon
widget-stencilbar-livescore__icon--live-now"

<label class="widget-stencilbar-livescore__icon-label">
<input type="checkbox"

autocomplete="off"
data-ga-label="Canli"

</div>，因此无法获得String那样的案例名称，因此您需要添加一种方法以自己返回它……
String答案 1 :(得分：1)
您可以从其rawValue创建一个枚举值，并使用within try-block
Exception in thread "main" java.io.IOException: Stream Closed
at java.base/java.io.FileOutputStream.writeBytes(Native Method)
at java.base/java.io.FileOutputStream.write(FileOutputStream.java:342)
at Main.demoMethod(Main.java:24)
at Main.main(Main.java:12)
获取其大小写字符串。
