Converting enum numeric value to ASCII in byte?

[TMattC]

So, I have an enum and want to get the ASCII code of the numeric value of a certain enum value. For example if I have the enum value STANDARD (=1), I want to get the ASCII code for '1' (49) in a byte variable. I cant seem to figure out how to do. Anyone?

enum PackageType : byte { STANDARD=1, REQUEST=2, ANSWER=3 }

PackageType type = PackageType.STANDARD;
byte b = (byte)type; // This results in b==1, I want the ASCII (49)

How about make STANDARD=49 ? Other options include applying an attribute to the member: [System.ComponentModel.DescriptionAttribute('1')] STANDARD=1 http://msdn.microsoft.com/en-us/library/system.componentmodel.descriptionattribute(v=vs.110).aspx[^]

((int)type).ToString();

Or, if you want just the first character:

((int)type).ToString()[0];

The difficult we do right away... ...the impossible takes slightly longer.

[PIEBALDconsult]

Or type.ToString("D")

"How about make STANDARD=49 ?" Well, I guess it´s time to call it a night. Lol I´ll make STANDARD=49.

Well if you can change you enum you could do this:

enum PackageType
{
Standard = '1',
Request = '2',
Answer = '3'
}

And that's job done. If not, just add 48 to 'b'.

Yet another option would be a conversion function as follows:

enum PackageType : byte { STANDARD, REQUEST, ANSWER }

static readonly byte[] PackageTypeValues = { (byte)'1', (byte)'2', (byte)'3' };

byte PackageTypeToByte( PackageType packageType )
{
return PackageTypeValues[(byte)packageType];
}

This has the advantage of separating the enumeration values from their display tokens, allowing you to change one without changing the other. The disadvantage is that they can become unsynchronized...

Yet another possibility:

public enum ByteEnum
{
FortyNine = (byte)'1',
Fifty = (byte)'2',
FiftyOne = (byte)'3'
}

// (int) ByteEnum.Fifty => 50

I keep thinking you want something other than an Enum here (a Struct ?), but I am not quite sure what that "other" might be.

«I'm asked why doesn't C# implement feature X all the time. The answer's always the same: because no one ever designed, specified, implemented, tested, documented, shipped that feature. All six of those things are necessary to make a feature happen. They all cost huge amounts of time, effort and money.» Eric Lippert, Microsoft, 2009

byte[] result = Encoding.ASCII.GetBytes(PackageType.STANDARD.ToString());
