Say we have a UI and in this UI we have a dropdown. This dropdown is filled with the translated values of an enum.
Bow, we have the possibility to sort by the int-value of the enum, by the name of the enum, and by the translated name of the enum.
But what if we want a different sorting than the 3 mentioned above. how to handle such a requirement?
Implement your own IComparer
:
using System;
using System.Collections.Generic;
namespace test {
class Program {
enum X {
one,
two,
three,
four
}
class XCompare : IComparer<X> {
public int Compare(X x, X y) {
// TBA: your criteria here
return x.ToString().Length - y.ToString().Length;
}
}
static void Main(string[] args) {
List<X> xs = new List<X>((X[])Enum.GetValues(typeof(X)));
xs.Sort(new XCompare());
foreach (X x in xs) {
Console.WriteLine(x);
}
}
}
}
