How can enums be converted to strings in C#?

In C#, you can convert an enum to a string using the ToString() method.

Here is an example:

enum DaysOfWeek
{
    Monday,
    Tuesday,
    Wednesday,
    Thursday,
    Friday,
    Saturday,
    Sunday
}

class Program
{
    static void Main(string[] args)
    {
        DaysOfWeek day = DaysOfWeek.Monday;
        string dayString = day.ToString();
        Console.WriteLine(dayString); // 输出 "Monday"
        
        Console.ReadLine();
    }
}

In the example above, we defined an Enum called DaysOfWeek, set the day variable to DaysOfWeek.Monday, converted the enum to a string using the ToString() method, assigned the result to the dayString variable, and finally outputted dayString to the console.

Please note that the default ToString() method of an enumeration will return the name of the enumeration. If you require a custom string representation for the enumeration, you can use the [Description] attribute within the enumeration and write a helper method to retrieve the value of that attribute. For more information on how to customize the string representation of an enum using the [Description] attribute, please refer to the relevant documentation.
