Hi,
I have arr from type byte = byte[] arr=new byte[4];
I want to insert to the arr select from enum when the number of selection is 4 digits

for example: arr=enumX.y; y=1011;

How can I convert and insert this value (y) to the arr?
I want the arr to look : arr[0]=1,arr[1]=0,arr[2]=1,arr[3]=1

Thanks in advance

Try this solution - your number(y) you can divide by 10 and add result ot the end of byte[].
Good luck)

what? How can this work?

when you divide 1011 by ten you get 101.1. Then you can round to 101 and get value after point(in this case 1) and add it to the end of byte[]. And so on in loop. In this case you need to run loop 4 times.

Not a problem

This how the enum look like:
public enum enumX
{
y=1011,
Z=1001,
}
The problem, is that when I write : var o= enumX.y;
o equal to y and not to 1011...so I can not divide the value...
why? and how can I change that?

You need to get int value from enum? int someIntValue = (int) enumX.y;

Ok, and then I have to divide the number? there is no another way to do this?

Alexander Dymshyts 23-Oct-13 11:28am

what is the problem with this way? What to do next I described in my first comment here)

Member 10304617 23-Oct-13 12:12pm

I do not have problem with this way... I am just looking for something else instead of dividing in loop...I thought that there is a function that does it... but if not I will use this solution...
Thank you!

Maybe you can tell us what you want to achive by this. But chances are high you need something like this:

C#

System.BitConverter.GetBytes(enumX.y);

this functions has some overloads and should give you the single bytes for the common value types (your enum is based on an integer, if you didn't specify another base type the default is int32).

Does this help?

So what you want is to convert the enum values to single digits, and store them into the Byte array? I found a way by converting to a string and parse it as Bytes. maybe you like it?

C#

using System;

namespace EnumValueToDigits
{
    class Program
    {
        public enum SomeEnum
        {
            Y = 1011,
            Z = 1001
        }

        static void Main(string[] args)
        {
            SomeEnum z = SomeEnum.Z;

            byte[] abyZ = EnumDigitsToByteArray(z);

            foreach (byte by in abyZ)
                Console.Write(by);

            Console.ReadKey(false);
        }

        static byte[] EnumDigitsToByteArray(SomeEnum e)
        {
            string strEnumValue = ((int) e).ToString();

            byte[] abyDigits = new byte[strEnumValue.Length];
            for (int i = 0; i < strEnumValue.Length; i++)
            {
                abyDigits[i] = byte.Parse(strEnumValue[i].ToString());
            }
            return abyDigits;
        }
    }
}
