Question

我有两个枚举

public enum YogabandEventDuration
{
    [Display(Name = "30 min")]
    ThirtyMinutes = 30,
    [Display(Name = "45 min")]
    FortyFiveMinutes = 45,
    [Display(Name = "60 min")]
    SixtyMinutes = 60,
    [Display(Name = "75 min")]
    SeventyFiveMinutes = 75,
    [Display(Name = "90 min")]
    NinetyMinutes = 90
}

public enum PrivatePrice
{
    [Display(Name = "$8.95")]
    ThirtyMinute = 895,
    [Display(Name = "$14.95")]
    FortyFiveMinute = 1495,
    [Display(Name = "$19.95")]
    SixtyMinute = 1495,
    [Display(Name = "$24.95")]
    SeventyFiveMinute = 2495,
    [Display(Name = "$27.95")]
    NinetyMinute = 2795
}

有没有办法将每个枚举中的值一对一匹配，以便我可以像这样进行搜索

var theClassPrice = GetPrice(YogabandEventDuration);

传递ThirtyMinutes将返回895

Answer 1

按照@SteveJ的建议，我个人会采用类似的方法

var privateSession = new Dictionary<Session, double>()
{
   { Session.ThirtyMinute, 8.95},
   { Session.FortyFiveMinute, 14.95 },
   { Session.SixtyMinute, 19.95  },
   { Session.SeventyFiveMinute, 24.95 },
   { Session.NinetyMinute, 27.95 }
};

然后使用一个枚举作为会话时间

public enum Session
{
    ThirtyMinute,
    FortyFiveMinute,
    SixtyMinute,
    SeventyFiveMinute,
    NinetyMinute
}

Answer 2

即使这确实很奇怪：您可以parse一个字符串来获取等于枚举的值。

var time = YogabandEventDuration.ThrityMinutes.ToString();
var price = Enum.Parse(typeof(PrivatePrice), time );
var intValue = (int)price;

为您提供一个简单的功能：

private int GetPrice(YogabandEventDuration duration) {
    return (int)Enum.Parse(typeof(PrivatePrice), duration.ToString());
}

合并集合中的两个枚举以获取值之一
