C# 数字枚举值作为字符串

问题描述

我有以下枚举:

public enum Urgency {
    VeryHigh = 1,
    High     = 2,
    Routine  = 4
}

我可以像这样获取枚举值"作为字符串:

((int)Urgency.Routine).ToString() // returns "4"

注意:这不同于:

Urgency.Routine.ToString() // returns "Routine"
(int)Urgency.Routine       // returns 4

有没有一种方法可以创建扩展类或静态实用程序类，以提供一些语法糖?:)

Is there a way I can create an extension class, or a static utliity class, that would provide some syntactical sugar? :)

推荐答案

你应该能够使用 Enums ToString 方法的重载给它一个格式字符串，这会将枚举的值作为字符串打印出来.

You should just be able to use the overloads of Enums ToString method to give it a format string, this will print out the value of the enum as a string.

public static class Program
{
    static void Main(string[] args)
    {
        var val = Urgency.High;
        Console.WriteLine(val.ToString("D"));
    }
}

public enum Urgency
{
    VeryHigh = 1,
    High = 2,
    Low = 4
}
