How can I Enumerate an enum in C#?


How can I Enumerate an enum in C#? Here is my current code, and it does not works:

public enum DayOfWeek
{
    Mon,
    Tues,
    Wed,
    Thur,
    Fri,
    Sat,
    Sun
}

public void EnumerateAllDaysOfWeekMethod() 
{
    foreach (DayofWeek dow in DayofWeek) 
    {
       // DoSomething with dow;
    }
}

And gives the following compile-time error, so how to solve it and loop through each day?

You can use GetValues method to iterate through enums, so your code will be

var values = Enum.GetValues(typeof(DayofWeek));

so your complete code will be

foreach(var item in Enum.GetValues(typeof(DayofWeek)))
{
//do something here
}

I have explained all the details of enum  in C# in this article, take a look

Loop using "GetValues" method, here is sample code

foreach (var val in Enum.GetValues(typeof(DayofWeek)))
{
   Console.WriteLine(val);
}

You can also create custom helper functions too:

public static class EnumUtil {
  public static IEnumerable<T> GetValues<T>() {
    return Enum.GetValues(typeof(T)).Cast<T>();
  }
}


//Call it like..
var values = EnumUtil.GetValues<DaysOfWeek>();

 you can also use Enum.GetName(typeof())

public enum Suits
{
    Spades,
    Hearts,
    Clubs,
    Diamonds,
    NumSuits
}

public void PrintAllSuits()
{
    foreach (string name in Enum.GetNames(typeof(Suits)))
    {
        System.Console.WriteLine(name); //Prints Spades, Hearts etc...
    }
}
