How to perform LINQ query over Enum?

Question

Below is my Enumerator List:

public enum StatusEnum
{
    Open = 1,
    Rejected = 2,
    Accepted = 3,
    Started = 4,
    Completed = 5,
    Canc         


        

Answer 1

Steps:

• Get the enum values and cast the results to the type of the enum
• Sort the enum values by their integer values (otherwise they sort naturally by unsigned magnitude)
• Take the first 4

Code:

return Enum.GetValues(typeof(Activity.StatusEnum))
.Cast()
.OrderBy(se =>(int)se)
.Take(4);

Output:

Open Rejected Accepted Started
