C# enum to string auto-conversion?

问题

Is it possible to have the compiler automatically convert my Enum values to strings so I can avoid explicitly calling the ToString method every time. Here's an example of what I'd like to do:

enum Rank { A, B, C }

Rank myRank = Rank.A;
string myString = Rank.A; // Error: Cannot implicitly convert type 'Rank' to 'string'
string myString2 = Rank.A.ToString(); // OK: but is extra work

回答1:

No. An enum is it's own type, if you want to convert it to something else, you have to do some work.

However, depending on what you're doing with it, some tasks will call ToString() on it automatically for you. For example, you can do:

Console.Writeline(Rank.A);

回答2:

You are not probably looking for enums itself, but a list of string constant. It can fit your needs better in some scenarios.

Use this instead:

public static class Rank
{
   public const string A = "A";
   public const string B = "B";
   public const string C = "C";
}

回答3:

No, but at least you can do things with enums that will call their ToString() methods when you might need to use their string value, e.g.:

Console.WriteLine(Rank.A); //prints "A".

回答4:

The correct syntax should be

myRank.ToString("F");

回答5:

[Caution, hack] Unsure as to whether this is nasty, to me it seems a reasonable compromise.

var myEnumAsString = MyEnum+""; Console.WriteLine(myEnumAsString); //MyEnum

This will force implicit ToString()
