Question

I have an enumeration for Status for a Task. Some of the statuses are considered obsolete, and I have marked them as obsolete, as seen below:

public enum TaskStatus {     [Description('')]     NotSet = 0,     Pending = 1,     Ready = 2,     Open = 3,     Completed = 4,     Closed = 5,     [Description('On Hold')][Obsolete]     OnHold = 6,     [Obsolete]     Canceled = 7 } 

In my user interface I populate a drop down with values on the enumerations, but I want to ignore ones that are marked as obsolete. How would I got about doing this?

You could write a LINQ-query:

var availableTaks = typeof (TaskStatus).GetFields(BindingFlags.Static | BindingFlags.GetField | BindingFlags.Public)     .Where(f => f.GetCustomAttributes(typeof (ObsoleteAttribute), false).Length == 0); foreach(var task in availableTaks)     Console.WriteLine(task);
