Enum problem

deviousdexter · 04-29-2009, 07:41 AM

just a quickie - my head seems to have gone blank

i have an enum

Code:

public class1
{
public enum types
{
  car=1,
  bike =3,
  trailer=5,
  lorry = 11
}
}

i have a value ( say 5) - can i get the string ("trailer") into a text box this way ?

Code:

int value = 5;
textbox1.text = ????   <----- get the word 'trailer' to go to text box please

am i doing this the right way round or is an enum not the way i need to do it.

would i be better with a switch/case statement ?

thanks

You should use a hashtable if you want to do something like that (dictionary in C#). Otherwise just make an enum of type types (in your case), assign it one of its respective enum values, and then call toString().

Code:

enum MyEnum { One, Two, Three }
System.Enum.GetName(typeof(MyEnum), MyEnum.Two);

Code:

int value = 5;
textBox1.Text = ((types)value).ToString(); // should be trailer

Code:

static partial class Extenstions
{
     static public string GetString(this Enum p_enum) {
          return Enum.GetName(p_enum.GetType(), p_enum);
     }
}

Code:

Numbers k = Numbers.One;
Console.WriteLine(k.GetString()); //One

Sorry i thought i had posted back to this thread, must have forgotten the submit button.

both the Theoobe and Magos' solutions were tried and did what i needed - i opted for Magos solution for no particular reason.

Sorry for leaving the thread in flux.
