How can I cast int to enum?

Question

How can an int be cast to an enum in C#?

Answer 1

The following is a slightly better extension method:

public static string ToEnumString(this int enumValue)
{
    var enumString = enumValue.ToString();
    if (Enum.IsDefined(typeof(TEnum), enumValue))
    {
        enumString = ((TEnum) Enum.ToObject(typeof (TEnum), enumValue)).ToString();
    }
    return enumString;
}
