# Mode of list of numbers - VB [closed]

I have an array of numbers created by the user, the array is sorted and I can find the Average, Median, Max, Min, Lowest -> Highest, Highest -> Lowest. Now I just need to find the mode. Here is the code I made that works if there is only 1 Mode, I need to make it work to find 3 modes .. I.e. if the array was [1,1,1,2,2,2,3,3,3,5,6] then the mode would be 1 , 2 , 3

    Dim countermode As Integer
Dim w, s, r, i, p, tempmode As Integer
p = 1
Sort(marks)

For w = (x - 1) To 0 Step -1

p += 1

For s = (x - p) To 0 Step -1
r = marks(w)
i = marks(s)

If i = r Then
countermode += 1
tempmode = marks(w)
End If
Next

Next

lblmode.Text = tempmode

what is mode? it is related to the sorting logic. – paritosh Dec 21 '12 at 16:09
@paritosh - Mode is the subset of numbers which appears the most frequently within a set. – Bobson Dec 21 '12 at 16:20
A wonderful write-up on just this functionality in Linq can be found here: LinqMode – dgp Feb 6 '13 at 15:28

In C#:

var list = arr.GroupBy(x => x)
.Select(x => new { Count = x.Count(), Value = x.Key })
.GroupBy(x => x.Count)
.OrderByDescending(x => x.Key)
.First()
.ToList();


Automatically converted to VB.NET:

Dim list = arr.GroupBy(Function(x) x) _
.[Select](Function(x) New With { _
Key .Count = x.Count(), _
Key .Value = x.Key _
}) _
.GroupBy(Function(x) x.Count) _
.OrderByDescending(Function(x) x.Key) _
.First() _
.ToList()


You might want to make it more idiomatic.

Fascinating, +1 for the C# code, -1 for the VB code, that stuff is just plain horrible to look at and should not be. – konijn Dec 21 '12 at 16:09
As I said, it was an automatic conversion. I didn't learn to work with LINQ until after I switched to c#, so I couldn't tell you what it should look like. – Bobson Dec 21 '12 at 16:16
Edited to make it look cleaner, at the very least. – Bobson Dec 21 '12 at 16:18
