如何将字符串转换为枚举? [英] How to convert a string to a enum?

问题描述

我正在尝试在PowerShell中将字符串转换为枚举值，但在任何地方都找不到...

I'm trying to convert a string to a enum value in PowerShell but couldn't find this anywhere...

我得到一个JSON结果，我只想使用定义为字符串的Healthstate.

I'm getting a JSON result, where I only want to consume the Healthstate which is defined as a string.

enum HealthState
{
    Invalid = 0
    Ok = 1
    Warning = 2
    Error = 3
    Unknown = 65535
}
$jsonResult = "Ok"
$HealthStateResultEnum = [Enum]::ToObject([HealthState], $jsonResult) 

谢谢.

推荐答案

您可以简单地将字符串结果转换为Enum类型:

You can simply cast the string result as the Enum type:

$HealthStateResultEnum = [HealthState]$jsonResult

无论 $ jsonResult 包含枚举类型的字符串还是值，这都将起作用.

This will work whether $jsonResult contains a string or value from the enum type.
