I have this issue in VB.Net.
I have a List of type String.
Dim list As New List(Of String)
This list may or may not contain Duplicates.
Now what i want is, lets say the list has values {"10", "10", "10", "11", "11", "12"}
I want to create an Array(2-dimensional)/List which will give me value like this.
(3,10;(2,11);(1,12)
Simple means 10 exists 3 times, 11 exists 2 times and 12 exists 1 time.
Please don't dive me any LINQ
replies as i am using VB.Net 2.0
In .NET 2, you'll have to track this yourself. The simplest way would likely be to build your own Dictionary(Of String, Integer)
to store the counts, and loop manually:
Dim dict = New Dictionary(Of String, Integer)
For Each value in list
If dict.ContainsKey(value) Then
Dim count = dict(value)
dict(value) = count + 1
Else
dict(value) = 1
End If
Next
' dict now contains item/count
For Each kvp in dict
Console.WriteLine("Item {0} has {1} elements", kvp.Key, kvp.Value)
Next
