All Enum items to string (C#)

How to convert all elements from enum to string?

Assume I have:

public enum LogicOperands {
        None,
        Or,
        And,
        Custom
}

And what I want to archive is something like:

string LogicOperandsStr = LogicOperands.ToString();
// expected result:  "None,Or,And,Custom"

A simple and generic way to convert a enum to something you can interact: 

public static Dictionary<int, string> ToList<T>() where T : struct
{
   return ((IEnumerable<T>)Enum.GetValues(typeof(T))).ToDictionary(item => Convert.ToInt32(item), item => item.ToString());
}

and then:

var enums = EnumHelper.ToList<MyEnum>();

You have to do something like this:

var sbItems = new StringBuilder()
foreach (var item in Enum.GetNames(typeof(LogicOperands)))
{
    if(sbItems.Length>0)
        sbItems.Append(',');
    sbItems.Append(item);
}

Or in Linq:

var list = Enum.GetNames(typeof(LogicOperands)).Aggregate((x,y) => x + "," + y);

Although @Moose's answer is the best, I suggest you cache the value, since you might be using it frequently, but it's 100% unlikely to change during execution -- unless you're modifying and re-compiling the enum. :)

Like so:

public static class LogicOperandsHelper
{
  public static readonly string OperandList = 
    string.Join(",", Enum.GetNames(typeof(LogicOperands)));
}

string LogicOperandsStr 
     = Enum.GetNames(typeof(LogicOoperands)).Aggregate((current, next)=> 
                                                       current + "," + next);

foreach (string value in Enum.GetNames(typeof(LogicOoperands))
{
    str = str + "," + value;
}
