ArrayFromEnumInit.cs

// Remember: This is a very simple example. enum's with gaps will not work as expected ... 
enum JobStatsIdx
{
  None = 0,
  First = 1,
  Second = 2,
  Third = First | Second,
  Eight = 8,
  Nine = 9
};

// Array initialization Without LINQ
int[] jobStatsIdxStartValues = Array.ConvertAll(new int[Enum.GetNames(typeof(JobStatsIdx)).Length], v => 0);
// With LINQ
Enumerable.Repeat(0, Enum.GetNames(typeof(JobStatsIdx)).Length).ToArray()
  
 Result:
Array[0] = 0;
Array[1] = 0;
Array[2] = 0;
Array[3] = 0;
Array[4] = 0; // wrong Must be index 8
Array[5] = 0; // wrong Must be index 9
