Space between words in enum type?

[mrdance]

Is the following possible in any way?

public enum Country {
"United Kingdom" = 1
}

With such syntax there is no way using enum but using a Hashtable could be a solution of what you search:

Hashtable ht = new Hashtable();
ht.Add("United Kingdom",1);
ht.Add("Brazil", 25);
ht.Add("USA",19);
ht.Add(1,"United Kingdom");
ht.Add(25,"Brazil");
ht.Add(19,"USA");
object val=null;
object key=null;
if (ht.ContainsKey("United Kingdom"))
{
	val = ht["United Kingdom"];
}
if (ht.ContainsValue(19))
{
	key = ht[19];
}

Thanks but I want the contents to be displayed at designtime.

Use an underscore instead of a space, then.

With Enum you will have restriction, you can't have free text format.
So if you need exactly what you need as a text description for the option which can have spaces and special characters you must use class inherited from UITypeEditor:
Here is a complete code:

        /// <summary>
        /// Specifies the _Format for displaying and printing numbers, dates, times, and text.
        /// </summary>
        [Bindable(true), Category("Text"), DefaultValue(""), Editor(typeof(FormatEnum), typeof(UITypeEditor)), 
        Description("Specifies the _Format for displaying and printing numbers, dates, times, and text.")]
        public string Format
        {
            get{return this._Format;}
            set
            {
                if (this._Format != value)
                {
                    this._Format = value;
                    //this.Mask = ReplaceFormatCharacters(value);
                }
            }
        }


    #region enum designer
    /// <summary>
    /// Klasa vo koja se menuva propertyto vo sloboden tekst
    /// </summary>
    public class FormatEnum : UITypeEditor
    {
        private IWindowsFormsEditorService edSvc = null;
//        private ToolTip tooltipControl;
        private ListBox lst;
        private string[] formats = {"Only Text", "Only numeric"};
